Why Is Champion Diesel Oil Blue?

There are so many varieties of blue: Ultramarine, Cobalt Blue, Indigo, Navy Blue, Prussian Blue, Electric Blue and Cerulean just to. name a few. 

Blue has been an important color in art since ancient times. For thousand of years the ancient Egyptians produced a blue pigment using calcium copper silicate that is considered the first synthetic pigment. 

Surveys show that blue is the color most commonly associated with security, trust, and loyalty. And it’s chosen by a majority of both men and women around the world as their favorite color. 

Champion dyes its Blue Flame Diesel Engine Oils for several reasons. The robust chemical formula is unique and provides an industry-leading performance to meet the needs of both older and next generation heavy-duty engines, thus providing users the security of knowing that the blue oil is protecting them. The blue color also allows the quick-lube, fleet, or end-user to have absolute assurance and trust that no substitute engine oil is being installed. Also, Blue Flame creates a loyalty from followers that always ask for the “Blue Oil”.

 

“Champion Blue Flame Diesel Oils will forever be recognizable and have a distinctive appearance”, said Karl Dedolph, director of racing and performance products at Champion Brands, LLC. “It’s a huge plus when someone doesn’t even have to see the label to know it’s a Blue Flame product – the color alone is enough to identify the diesel engine oil. The dye is chemically balanced when it is blended and does not create any kind of lubricant issue or problem with additives or base stock.”

 

“The blue dye doesn’t leave a residue in the engine. In fact, the oil over time will turn and look black in color. It’s actually soot, which the diesel engine produces in much higher levels than gasoline motors. The soot enters the oil pan from the combustion chamber due to the gap in the piston rings. The black color, which is very common, doesn’t mean the oil has a problem,” added Dedolph.

 

Blue Flame Diesel Engine Oils are formulated with workhorse high-zinc performance additives, superior protection, advanced polymer technology, and high TBN, supported by a carrier blend of synthetic fluids.

 

In addition, Blue Flame Diesel Engine Oils deliver unmatched high temperature film strength and lubricity protection, with the muscle to combat oil shear and maximize sustained cylinder compression. They also inhibit oxidation, corrosive acids, sludge and varnish build-up.

 

These oils keep your engines going longer by reducing soot-induced engine wear, controlling abrasive soot contamination and preventing high temperature corrosion, even while allowing for improved fuel economy and lower total cost of ownership. They are proven to increase engine horse power and torque.

Champion Blue Flame Diesel Engine Oils are purpose built for extreme protection and performance. https://www.championbrands.com/diesel-engine-oils/

Next time you need oil for your Cummins, Powerstroke or Duramax, ask for that “Blue Oil,” Champion Blue Flame Diesel Engine Oil. 

The Silverado Trail Boss Steps Up to Diesel

Silverado Trail Boss now available in diesel.

Some people might be surprised at how long the Chevy Silverado half-ton went without a diesel engine. When you go to performance diesel competitions, the Big 3 are always well represented. But for a while the diesel option was absent in recent years. So it was that in 2020 that the Silverado stepped up its game with a turbo diesel inline six.

At the time, automotive columnist Len Ingrassia wrote last year, "The new turbo diesel inline six cylinder promotes high fuel economy, performance and a plethora of configurations to match your pocketbook and penchant for creature comforts." 

We find it interesting that GM is now adding a diesel option to the Chevy Silverado Trail Boss. As reported earlier this year, GM has its sights set on going all electric by the middle of this century. Needless to say, they obviously do not want to abandoned the diesel enthusiasts among us. Hence, GM Authority last week announced this new move for the 2022 Chevy Silverado 1500 Limited LT Trail Boss.

According to a story by Caleb Jacobs in The Drive, the Trail Boss is currently considered the most off-road capable truck in Chevy's half-ton lineup. 

Jacobs notes that "the 3.0-liter Duramax diesel inline-six that hasn't been available on the Trail Boss to this point, and it'd be great to pair that 4x4 prowess with nearly 30 mpg on the road. Now, it seems like General Motors will make it happen."

The 3.0-liter Duramax produces 277 horsepower and 460 pound-feet of torque. That's equal to GM's potent 6.2-liter gas V8. The V8 can't compete on fuel economy though. Off road in 4x4 mode, Duramax numbers are 25 mpg. Running down the highway you get 29 mpg.

We applaud the move, especially since Ford is discontinuing its half-ton diesel after this month. Ram will no doubt pick up the slack with its EcoDiesel V6-powered half-ton trucks, including the Rebel 1500.

Special thanks to the industry journalists who work at keeping us informed of all the latest developments in our industry as they happen.

Diesel Motorsports: Most Fun You Can Get in a Weekend

Great story by Jeff Zurschmeide on the PRI website. Diesel motorsports is far from dead, and is even growing. The article, titled Shake, Rattle & Roll, describes how diesel motorsports have become a powerful niche market that is drawing in more people every year.

The author begins by making the same observation I've made over many years of going to races. Most racers use a diesel powered vehicle to pull their race car to the track which is gas powered. Today, diesel is no longer for tow vehicles. There is a huge, enthusiastic diesel motorsports culture. This diesel world includes engine builders, aftermarket providers and sanctioning bodies as well as the sponsors and businesses that provide products for the racers. Altogether it's a great show for the fans. 

Zurschmeide notes that drag strips are the primary venues for diesel racing, with a strong second being presence at pulling competitions. Diesel has also found some surprising success in sports car racing as when Audi proved that a diesel-powered car could compete at the highest levels. In 2006-2008 Audi’s TDI prototypes won the prestigious 24 Hours of Le Mans three years in a row.

That last bit about Le Mans is no laughing matter. Audi and other automakers have developed some powerful diesel power plants, as we noted recently regarding Daimler's powerful new diesel engine for their Mercedes Benz.

That having been said, the mass market for diesel motorsports in America still remains almost entirely limited to straight-line power contests. For now.

Trucks are King in the diesel motorsports scene, which is a grassroots movement driven by an appreciation for power. This need for power is what drives engine builders to satisfy the hunger. Cummins, Duramax and Power Stroke are the main foundations, but innovative builders augment these engines to maximize their capabilities. 

The full article goes much deeper. Check it out by following the first link below.

Featured Diesel-Powered Vehicle of the Week: Wade Moody's Rail Dragster

Duramax Diesel to the Max

For the past several Mondays we've been featuring various head-turning diesels to start our week. So far we've been highlighting vehicles highlighted by CarBuzz in a 2019 article titled Cool and Crazy Diesel Powered cars. Today the spotlight is on Wade Moody's rail dragster. 

If you have an eye-popping or heart-stopping diesel truck you'd like to see featured here, tell us about it so we can share it. 

Wade Moody who has created a lot of buzz indeed. By the time he was 32 he had been racing half his life. For sure, diesel engines seem to be part of his DNA. According to Diesel World, Moody turned to diesel drag racers in 2006 with a 4WD Cummins-powered Dodge Ram, competing in the Pro Street class. After winning a few championships at that level, he acquired an S-10 drag truck and moved into the Pro Stock class.

The truck had a powerful Duramax engine, which he fine tuned into another top dog racing machine. This truck powered him to championships in 2011, 2012 and 2013. A crash in 2014 put an end to this truck's reign as fastest diesel drag truck.

Despite this setback, Moody was fortunate in that the engine and Turbo 400 tranny survived. Once transferred into a new frame, he had the fastest Duramax-powered dragster in the known world. 

It was a three month build but fitting the Duramax into the rails proved to be a worthy ambition. By the end of 2015 the machine was doing test passes and the new configuration being readied for war. Even before it had all been worked out they were making passes of 7.02 seconds or 195.48 mph. None of these passes were under full power as they wanted to ensure things were tight. The were anticipating good things in 2016 and indeed achieved them.

With more refinement they became the first common rail diesel dragster to get down into the 6's with a first place win at the Midwest Truck Nationals. Time: 6.997 seconds @ 192.8 mph.

In July 2016 Brian Wagner of DragZine wrote a story about this achievement with additional details about the engine and the dragster. Wagner describes the ways in which Moody and his team squeezed out more power based on things they learned. Moody gave credit to his tuners John Jordan and Kroy Willis, "and all of the awesome products from the rest of our supporters that make it possible to go faster each season."

Check out this YouTube video in which Wade Moody talks about
all the details that went into this build.

The target they were aiming for was "Fastest Diesel in the World," a title owned by Jared Jones. His record pass of 225 mph a couple years earlier.  

Here are some links to the sources for this story and a pass on Moody's Facebook page.

Fastest Diesel Passes of 2020

Front end of the Firepunk Diesel S10

2020 was an unusual year for many reasons, from the global pandemic to social turbulence in many cities. Hard to believe, but there was no SEMA Show, no PRI, no Diesel Power Challenge. Things were so bad that Diesel World labelled it The Year of Cancelled Events.

People were bored, anxious, overworked, and many were unemployed. Nevertheless, there were still many exciting moments for the highlight reels for 2020. As we look in the rearview mirror we see new records set and a lot worth talking about, which is what Diesel World has done for us in this article by Mike McGlothlin titled Fastest Passes of 2020.

McGlothlin begins by noting that 2020 was actually a huge year for drag racing because drivers and teams stayed focused. They didn't allow what was going on around us to distract them from their aims, which is probably good advice for all of us who have dreams and goals. As a result, there were numerous records broken in 2020 and promising prospects for 2021.

After a condensed summary of 2020 we get photos and details about the main stories, beginning with the Quickest Diesel Dragster in the World, Scheid Diesel's billet-block, compound turbo, P-pumped Cummins-powered Spitzer chassis rail. Track conditions were perfect at October's PDRA and the Scheid team was ready. Boom... Elapsed Time on the 1/8th mile run, 4.04 seconds.  New record. 184 mph. Driver: Jared Jones.

It's gratifying when it all comes together. The record Jones broke had been set only 7 months earlier by John Robinson, a 4.101 second pass that screeched to 181 mph. One can expect these two drivers will be very conscious of one another as they push the envelope in 2021. The goal for each will be to break into the 3s. No doubt they can almost taste it.

A new car on the scene in 2020 was Jeremy Wagler's Duramax dragster. This diesel, too, is quick, and made real progress in its first season. This will be another driver and car to pay attention to going into 2021.

* * * *

In the diesel truck category the big dog to watch these past several years has been Firepunk Diesel out of Ohio. The Pro Mod S10 has been setting records all along, and the sacrifices they've made have been rewarded with many trophies and achievements along the way. The Diesel World story shared the impressive numbers they produced in October, but failed to note their Cummins-powered breaktrhough into the 3s that later took place in Florida. You can read about that here. Engine builder Lavon Miller and driver Larson Miller will remain in the forefront of what's happening wherever they go in 2021.

* * * *

When you scroll through McGlothlin's article you'll find diesel-powered Corvettes, pickups, dragsters and pro street vehicles with Duramax, Cummins and Power Stroke engines. Racing is one of the ways engine manufacturers explore the cutting edge of what's possible in engineering technology. 

You's also find the drivers and teams to watch in 2021.

Heart-Stopping Power: Gale Banks' 1200-HP Tri_Charged Duramax

When it comes to motorheads, the hunger for power seems near universal. According to Wikipedia, hot rodding was birthed in Southern California in the late 1930s. People raced modified cars on dry lake beds northeast of L.A. with rules established by organizations like the Southern California Timing Association (SCTA). Unofficial street racing took place anywhere where you had more than a handful of teens and a stretch of straight, flat road.  

Most of these teens grew up and moved on, pursuing careers, supporting families. Then there were the others for whom the experience of speed and power ignited a passion that became the fuel that powered their careers. One of these  boys with an aptitude for mechanics was Gale Banks, now president of Gale Banks Engineering. Three parts engineer, one part "mad scientist", Banks has spent a half century tinkering with technology, keenly focused on improving the internal combustion engine. His special interest has been diesel engines.

To give you an idea of just how far Gale Banks is willing to go to extend the capabilities of diesel engines, Greg Acosta wrote this story for EngineLabs.com: More Power With Less Boost: Banks 1,200-HP Tri-Charged Duramax.

One of the things that makes this article so significant is that the author is not only writing about a briilliant engine builder at the height of his powers, we're encountering the rare transparency of a man who is sharing everything openly. Banks has been part of a world where secrets are the norm. Competition means finding an edge, not sharing your edge. 

The Duramax engine Banks has been incrementally improving is suitably named "Mad Max". It's something he's been focused on and fine tuning for two-and-a-half years. In this article we don't just read details about the power this setup can achieve. In addition, Banks provides a breakdown of what all the readouts mean, and what the dyno data really means. As Acosta puts it, "In a world where data is hoarded and protected like the gold in Fort Knox, Banks is freely sharing not only his findings, but explaining the findings as well."

For Banks, one of the key metrics is Manifold Air Density (MAD). Since it's a Duramax he's been playing with, could this acronym be the secret to why he calls this engine a Mad Max?

Acosta writes, Using his preferred metric of Manifold Air Density, Banks breaks down the amount of air he needs to reach his 1,200-horsepower goal, and how, exactly, it will be measured on the dyno. “Manifold Air Density is the best indication of the engine’s power potential. You can forget about boost pressure, because it’s part of the MAD calculation. Manifold Air Density is the bottom line,” says Banks.

The engine was originally built for a Monster Truck. If you'veever wondered what those monsters had under the hood, this story will peak your interest on that level, too. The photos draw you in, but the details are what make this a valuable article to be bookmarked by any serious gearhead seeking to learn how to make dyno adjustments for maximum diesel power.

A Duramax-Powered '67 Camaro. Is This For Real?

Here's another fun story from Artie Maupin, this time writing for Chevy Hardcore. It's titled Maxed Out: Dustin Hamm’s Duramax-Powered ’67 Chevrolet Camaro. It's a story drenched in detail with plenty of photos worth more than a thousand words each.

Those of us who lived through the muscle car era little realized how short lived that period of automotive history would last. Mustang, Charger, Barracuda, Road Runner, Camaro.... These were the cars dreams were made of. What caught our eye initially when this article posted a few days back was the unusual step of dropping a Duramax Diesel engine into a '67 Camaro. But when you read the story, it gets even better. This is a story about commitment.

The owner of the car is Dustin Hamm whose parents took ownership of the car in 1970, using it throughout the 70's as a street racer. Eventually, this became Dustin's baby to nurture and transform, and transform it he did, as Maupin writes, "Fast forward to now, it is plumbed and powered with a 6.6-liter LBZ Duramax engine making gobs of horsepower and torque. Crazy idea, right? Here is how it all went down."

When Dustin acquired the car it had been sitting since 1980, outside. That sentence alone says much. This was 2005, and the youth thought it might make a nice high school graduation project for the following year. 25 years is a long time for a car to sit, though, as he would eventually find out.

 

Hamm initially dropped in a 600-horsepower World Products Motown 454ci small-block engine, rebuilding the four-speed to handle it. “After this, I was hooked on horsepower,” Hamm said.  

As much fun as it was to have a powerful machine, he began thinking it could be even more fun having a great looking powerful machine, and in October 2006 he made up his mind to completely redo the car. Because he worked at a body shop he'd learned enough to tackle a project like this, he believed.

 

Step one is removing the paint, bondo and rust with an acid dip. Things proved to be far worse than he imagined once this first step was taken.

 

Meanwhile, he began looking around on Craigslist for a powerplant and tranny. This is where he found the 6.6-liter LBZ Duramax and a suitable transmission.

Maupin digs up details of the restoration that may not have even considered. Fabricating a rear chassis, cutting out the stock floor and replacing it as well as differentials, suspension, new floor, wheel tabs and, yes, a roll cage. This was definitely a serious endeavor and it took years. Dripping in the engine is what he called "the fun part." It took dozens of attempts to get the fitment right.

  

Each step resulted in the discovery of additional issues. For example, with that heavy new engine bearing down on the front end, the oil pan was almost touching the ground. They dealt with it, of course, but they are the problems you run into when "doing something that nobody else has done."

Once the engine was installed and bodywork set, it was time to attend to the paint job, a radiant Viper Red. The finish was a labor of love, and executed with such perfection that he got a promotion to lead paint technician and paint shop manager.

There's still more to the story, and you can see photos of the later stages here as well. Check it out here. Kudos to Artie Maupin for having captured Hamm's passion in print and sharing it at Chevy Hardcore.

2021 Chev Silverado Diesel Makes a Splash in Argentina

On January 1, GM Authority kicked off the year with a story about a 2021 Chevrolet Silverado that was unveiled in Argentina a few days before in Cariló Park. The Silverado 1500 is a diesel-powered gem, and as you can from the photo here it is dressed in silver so luscious it appears to be liquid.

Deivis Centeno, the author of the story, shared how this was a pretty big surprise when the Silverado was unveiled at the end of year event a couple days earlier. The silver LTZ is equipped with a Duramax turbo-diesel 3.0L LM2 inline-six engine that generates 281 hp and 457 pound-feet of torque.

Argentina has more than 14 million cars and trucks on the road, more than any other Latin or South American country other than Brazil and Mexico. It's understandable that GM is seeking to find the right vehicles to match customer needs in that country. The Silverado is part of this effort. 

The top five brands in Argentina are Volkswagen, Toyota, Renault, Chevrolet and Ford. The two American automakers are neck and neck. GM has made a commitment to zero in on what Argentinians are looking for. 8% of the people there live in rural communities where agriculture remains strong. Ford is the leader in pickup truck sales, which is why GM is eager to win hearts with the Silverado.

Centeno states, "The automaker announced that it will continue analyzing its target audience’s preferences and fine-tune the most appropriate offer for the 2021 Chevrolet Silverado in the Argentine market. As a result, it’s possible that some versions of the pickup featuring the 5.3L L84 V8 engine, with 355 horsepower and 383 pound-feet of torque, will also be available in Argentina."

The Silverado is expected to go on sale during the first half of this year. It's summer in this Southern hemisphere country at the Southernmost tip of South America. GM has chosen an exotic location to display its offerings, at a place called the Chevrolet Forest Walk, a 28,000 sq. foot area in the middle of a forest. Pretty cool digs.

GM, we wish you well in your efforts there.

Performance Diesel Podcasts for Your Listening Pleasure

There was a time when your only options for what to watch on television were what the networks produced and fed you. With the exception of ham radio enthusiasts, radio content was also created for delivery via the airwaves and you listened to what they generated. With the advent of cable television your choices were broadened, but also you were still limited.

Then the Internet came and the monopoly of the networks was broken forever. Nearly anyone could be a content producer or develop a show to share on YouTube, Vimeo or other platforms. In fact, 500 hours of new content is being uploaded to YouTube every minute. This amounts to 720,000 hours of content each day. Imagine how big Google's hard drives are to hold all that information.

Two decades ago the concept of RSS feeds was emerging and Podcasting began to emerge as a viable force. Podcasters are similar to radio programs except they use audio files that can be played on the listener's devices. Just as there are millions of people uploading videos to YouTube and Facebook, so too there are currently 850,000 podcasters who have produced over 30 million podcast episodes.

Many podcasters produce a series in which a host or hosts interview guests on a theme or cover news around a related topic. It should come as no surprise then that there are literally hundreds of podcasts for diesel enthusiasts. 

One way to find channels you like is simply to Google it.  Here's a popular one called Diesel Performance Podcast. DPP has been archiving shows since 2015. Recent topics include:

Over-Fueling Causes Black Smoke

Modifying a Cummins, Powerstroke or Duramax diesel engine with some sort of OBD-II plug-in or computer-controlled engine management system is one of the simplest ways to improve power for diesel racing and pulling. It’s really not that complicated. You don’t have to take the diesel engine apart, and the modifications cost far less than what’s required to get similar power gains as, for example, from a gasoline-powered motor. 

Because diesels “throttle-push” the amount of fuel injected into the engine rather than limiting the amount of air entering the engine, notable power gains can be achieved by just increasing the amount of fuel delivered. All that’s required is the aforementioned electronics box to alter the signals from the onboard computer that controls the timing and length of the fuel injector pulse and the fuel pressure. There are all sorts of diesel tuner boxes on the market that promise plenty of big power.  

While you can make more power with more fuel, if you don’t do it right, exhaust gas temperatures can go out of sight. This can spell eventual death for the diesel engine or turbocharger. Many diesel racers and pullers are unfortunately unaware of such potential engine damage. They love to increase power and are willing to assume some ownership of the risk, and that’s just what you do when you over-fuel a diesel. 

It is only after getting more airflow into, and out of, a diesel engine that max-power can be achieved safely.  These enhancements include a bigger or less restrictive intake path, inducting cooler air, bigger valves or different camshaft timing, a less restrictive exhaust system, increasing cylinder head flow through porting, turbocharging, or supercharging.

It’s no secret that max-power increases happen when you control both fuel and the airflow. If you don’t burn the extra fuel, then you’re increasing the exhaust gas temperature of a diesel engine  If the exhaust temperature isn’t too excessive, and if it occurs for only for a matter of a few seconds at a time, most diesel engines can withstand the abuse without incurring permanent damage, but there is always that risk.  

The telltale sign of over-fueling and lack of a balanced air flow strategy is excessive thick black smoke coming out of the exhaust pipe.

Did the Millennium Falcon use OBD-II?

“You’ve never heard of the Millennium Falcon? It’s the ship that made the Kessel Run in less than 12 parsecs,” exclaimed Han Solo, starship pilot. We’re sure they had OBD-II. If dashboard’s ‘check engine’ light came on, Han Solo would have known what to do.

For years vehicle manufacturers have fitted on-board diagnostic (OBD) systems that provide codes to help identify specific issues. You can find the most recent diesel powertrain codes for Duramax, Powerstroke, and Cummins in the right column of this blog. (See the button Diesel Technical Bulletins.)  

But what are these systems and what do these codes mean? Put simply, an OBD system, or on-board diagnostic system, is an on-board computer fitted to your diesel engine that monitors the performance of your truck, including its powertrain, ignition, gearbox and emissions system.

When the truck’s on-board diagnostics system identifies a problem with the vehicle’s performance, it turns on a dashboard warning light and registers a code that identifies the issue.

This engine code, called a Diagnostic Trouble Code (DTC), is stored in the OBD-II system and can only be accessed by connecting a scan, or diagnostic tool into the OBD-II diagnostic socket and reading the DTC off the display of the scanner.

This light is to let you know that a possible fault has developed in the engine management system or another function and may require attention. When you see this appear, check your handbook for instructions on what action to take for your make and model of vehicle.

Diagnostic Trouble Codes, also known as engine fault codes, are five-digit codes that identify a particular problem in the car. These codes are displayed on the scanning tool when it’s connected to the OBD system.

The five-digit DTC includes one letter usually followed by four numbers (e.g. P1234). Each individual combination of letters and numbers relates to a specific problem within the car, whether a generic issue or a manufacturer-specific error.

A DTC won’t tell you which specific part of your car needs fixing or replacing, but it will tell you -- or your mechanic -- what you need to test in order to diagnose the issue. Within the five-digit DTC, one of four letters (P, B, C, U) always comes first and relates to the part of the car that has the issue: P - powertrain, B - body, C - chassis, and U - network.

The second digit (either 0 or 1) relates to whether it’s a general issue (0) or a manufacturer specific problem (1), while the third corresponds to the specific system with the issue, such as the ignition, and can be either a number or letter. The final two digits are numbers that relate to the specific fault description, and there is no pre-approved key to help decode these final two digits.
