New Diesel Engine Oil Technologies Lead To Improved Performance and Efficiency

Since the mid-1970s the U.S. government has taken on the role of setting standards for fuel efficiency and reduction of emissions. In 1975 Congress implemented Corporate Average Fuel Economy (CAFE) standards, which has been a driver for much of the change that has occurred in engine design during the past five decades. The trigger at that time was the OPEC oil embargo that caused shortages and a spike in fuel prices, so the initial standards were more focused on fuel consumption.

Efforts to reduce emissions gradually increased in importance in subsequent decades. Along with engine design improvements it became apparent that more advanced lubricants were needed to achieve the goals being required by the National Highway Transportation Safety Administration (NHTSA) and the Environmental Protection Agency (EPA)

Near the end of July Fleet Owner magazine published a story about emissions efficiency related to new diesel engine oil technologies. The aim of this story is to help fleet owners and managers understand the new formulations being introduced to satisfy global fuel economy targets. What follows are some highlights from this article.

An engine oil's main task is to reduce friction and ensure that moving parts are kept from coming in contact with one another. (This latter function is why film strength is increasingly important.) Oil is also necessary to transfer heat away from the engine and remove impurities and debris that might collect on critical parts.

With the technical advances taking place in diesel engine, driven by the need for greater efficiency, the lubricants are experiencing greater stress. Not only must they perform under harsher conditions for longer oil-drain intervals, they must do so in the presence of biofuels, without compromising protection.

In recent decades we've seen the introduction of significantly thinner oils for automobiles. It's been recognized that there are also gains to be made in the heavy duty truck market by means of lower-viscosity oils. How far can one go without compromising engine durability?

The rest of this article presents the results of field trials by Shell pertaining to fuel economy in Class 8 trucks. The data they have analyzed is drawn from 39 million miles of testing with CK-4 and FA-4 technologies. (See: Understanding CK-4 and FA-4) 

The first benefit is that lengthened oil drain intervals can result in major oil savings for fleets due to fewer oil changes. Using a higher quality oil, as opposed to one meeting minimum standards, drain intervals would nearly double and oil usage nearly cut in half.

A higher quality diesel engine oil is more impervious to oil breakdown, which makes longer oil drain intervals possible. The majority of these oils use synthetic or hybrid basestocks. The article details Shell's tiered offerings for the various engine types. You can find the Champion Brand diesel oils for your application here.

This Custom-Designed Diesel-Powered Land Rover Served Britain's Prince Philip Well

With our editors on vacation, we're re-posting a few of our favorite stories from the previous year. This story, published this spring, caught a lot of eyeballs. 

Funerals are a pretty big deal when it comes to the rich and famous. This is especially so when royalty is involved That is why we saw news stories from nearly every angle regarding the the funeral of Prince Philip, Duke of Edinburgh. Most of these were articles about the life of Philip, of course, but also articles detailing the history of royal funerals through the decades, the dress code for such funerals, the things that are different from normal because of the pandemic, decisions made that may be unexpected, guest lists and other details that must be attended to.

And then there is the story of Prince Philip's custom-designed diesel-powered Land Rover that will serve as his hearse. 

I've heard of people building their own coffins, but this is the first time I've ever heard about a personally-designed hearse. It is a Land Rover that the prince has been tweaking for 16 or 18 years, depending on which news source your read. Either way, it's actually quite a story.

The Duke driving a Land Rover with the Queen in 1955.

It's well known that people who love Land Rovers really love them. They're dedicated. When Prince Philip began to consider his mortality, and all the fanfare that goes along with royal funerals, he simultaneously began sowing the seeds for a no-frills funeral, starting with the hearse itself. "Just stick me in the back of a Land Rover and driver me to Windsor," he purportedly told the Queen.

Specific decisions made by Prince Philip include the military green paint job, the open top rear, and special rubber grips on silver metal pins to hold the coffin in place. The vehicle itself is a Land Rover Defender TD5 130 chassis cab vehicle. Revealed Thursday for the first time, it generated much publicity on it own. 

According to Sky News, the Prince began the project in 2003 when he turned 82, working directly with Land Rover to get what he wanted. The selection of a 4-wheel drive Defender is intriguing. The Defender, introduced in the 1980s, was in 1998 fitted with a new 2.5-liter, five-cylinder inline turbodiesel engine badged the Td5, which replaced the Tdi in order to meet Euro III emissions regulations. Called either a straight five or an inline five, the cylinders are aligned in a row. It's both compact and efficient, using electronic control systems to produce 122 hp at 4850 rpm.  

There's symbolism in the selection of this vehicle. It's not ostentatious. It's sturdy and utilitarian, a functional vehicle for the common man. The Duke of Edinburgh was so enamored by the idea of using the Land Rover as a hearse that he made two backups in case something went wrong with the first during the intervening years from concept to this moment in time.

Throwback Thursday: Towing Insights We All Can Use

With our editors on vacation, we're re-posting a few of our favorite stories from the previous year. This story was published this past November.

One of the primary features of diesel engines--besides the fact that they last longer--is the power they generate for towing. Open your eyes and look around. What kinds of engines are doing all the work? It's diesel. 

So, whether you're towing horses to the county fair or hauling a bulldozer to a job site, your truck is likely a diesel powered machine.  

Having the right engine isn't the only thing you need to know about towing. While checking out the Diesel Power Products website yesterday I found this article on towing that was chock full of useful information for people who tow. Having written about towing in the past, I found it to be a fairly thorough discussion of issues you need to concern yourself with. These include:

Attaching the Load

Stopping the Load

Supporting the Load

Securing the Load

Balancing the Load

and Moving the Load

Years ago I heard a story about a bulldozer that slid off the back of a flatbed and killed two people because it wasn't properly secured. This is not an experience you want to have. When I was young I saw an inexperienced driver flip her car while towing a small house trailer. I was with my uncle who was a volunteer fireman and rescue squad worker. We were first on the scene and helped avert a bigger tragedy. 

If you ever do any towing, or plan to, this helpful article on The Basics of Towing with Your Diesel is informative and worth bookmarking.

Champion Blue Flame Diesel Engine Oil Recommended for Limited-Edition Shelby F-250 Super Baja Pick-Up

With our editors on vacation, we're re-posting a few of our favorite stories from the previous year. This story appeared in March.

In February the story broke about the new Shelby F-250 Super Baja Limited. It was a fun story because for many, this is what dreams are made of. The name alone is iconic, in part because of its celebrated history. It's not every day that you see a car designer featured on the silver screen. (Ford v. Ferrari) Then again, the Shelby story really does at times appear to be bigger than life.

So it with special enthusiasm that I read yesterday's news headline: 

Champion Blue Flame Diesel Engine Oil Recommended for Limited-Edition Shelby F-250 Super Baja Pick-Up 

Here's the rest of the story.

Champion Oil, a global leader in performance diesel engine oil now celebrating its 65th anniversary, announced that Shelby American is recommending Blue Flame Diesel Engine Oil  for its new Ford Shelby F-250 Super Baja, a Limited-Edition off-roading pick-up truck. 

“We deigned the Shelby F-250 Super Baja pickup to perform under extreme conditions, both on and off-road," said Gary Patterson, president of Shelby American. “With 6.7-liter V8 Power Stroke Turbo Diesel churning out 475-horsepower and 1,050 pound-feet of torque, the truck can really fly. For such an aggressive application, we recommend using Champion’s Blue Flame 15w40 CK4/SN Performance Diesel Engine Oil."  

Built for Shelby in Elkhart, Indiana, by Tuscany Motor Co., and in Las Vegas by the Shelby American team, the trucks will be sold at select Ford dealers in the U.S. Each will be documented in the official Shelby Registry. Production will be limited to only 250 vehicles.

Spotlight on the 1000hp Turbo Diesel Audi Quattro

With our editors are on vacation, we're re-posting a few of our favorite stories from the previous year. This story appeared in February

The name Audi is synonymous with quality. And why not? Throughout its history the company has epitomized German engineering. 

This week, Grand Tour Nation published an article by Alex Harrington about an Audi Quattro that makes over a thousand horsepower from its turbo-diesel engine. The story is accompanied by video footage that makes your mouth water. 

The Audi Quattro emerged from the road rally era. It made its first appearance at the 1980 German Motor Show in March of that year with production continuing through 1991. Right from the start the Quattro began winning rallies and races around the world, establishing itself a major force at the time. One item that contributed to its success was a rules change that allowed the use of four-wheel drive in competition racing. In part it seems to be a matter of being in the right place at the right time. 

Harrington begins his account of the car with a tip of the hat to that history.

The Audi Quattro was, and still is, a hero of the Group B Rally era. It used one of the first AWD systems to be used in anything other than off-roading, and that made it one hell of a force to be reckoned with on the stages. The thing is, this means these Quattros are extremely expensive, so many fans have resorted to buying the lower specced variants and modding them. This restomod from LCE Performance found in Markdorf, Germany, is the perfect example of this, and it’s been done very, very well.

Harrington himself comes out of a racing background, hence his interest in a the Quattro seems only natural. The story includes video, more focused on the feeling of the vehicle than words about it. You hear the whirr as the machine rips past the camera, going through the paces.

Under the hood you'll find a network of aftermarket intakes, orchestrated "to improve the amount of air that can be sucked into the turbo-charged five-cylinder engine." 

Here's a pair of sentences that speak volumes:

With 49lbs of boost, it hit 1,081 horsepower. Thankfully, it features a Quattro AWD system to maintain traction when putting those horses to the tarmac.

The power plant is a 2.5-litre turbo diesel from an Audi A6. This vehicle has more than power, though. It's got style.

Making a Splash in the Marine Market: Diesel Outboards Catch Our Attention

This week our editors are on vacation, so we're posting our favorite stories worth repeating from the previous year. This is a story that got a surprising amount of traction when it ran in January.

Just because half the lakes in the country are covered with ice doesn't mean we can't think about the upcoming boating season. Eric Haun, editor of Marine News, wrote an interesting article last summer in Marine Link titled "Making the Case for Diesel Outboards." In it he shares insights about transitions taking place in the marine arena.

Haun begins by pointing out how more and more professionals are switching away from inboard motors to outboards on small military craft, workboats, patrol boats another others kinds of vessels that were historically inboard engine powered. This gives the boats several advantages including easier access to maintenance, quicker replacement and the extra space available inside the boat.

At this point the discussion turns to diesel outboards, which have advantages of their own, one of the foremost being fuel safety. The author writes, Compared to gasoline, diesel is a less flammable fuel and therefore much safer to work with in all working environments. In addition, with diesel engines the combustion of fuel takes place due to the heat generated by the compression of fuel and air inside the cylinder. Compression ignition is safer than petroleum being ignited by a spark plug, or any other spark.

One of Haun's sources was OXE Marine, a Sweden-based diesel outboard manufacturer. According to Myron Mahendra, CEO of OXE Marine, “Many vessels are hindered by regulations to carry petrol onboard if fire safe containment is not provided. The use of petrol is, therefore, a challenge for any vessel with tenders.”

He also spoke with U.K.-based Cox Powertrain, which makes diesel outboards as well. Cox noted that NATO has been pushing a single fuel idea, with the aim of maximizing equipment interoperability by using a single fuel option. This is one of the drivers behind the CXO300 diesel outboard Cox Powertrain has developed.

The end result here is that rescue vessels, naval and military vessels can refuel at the mother ship without being burdened with the hazard of highly volatile gasoline.

"Another benefit associated with diesel is efficiency," writes Haun. "Both Cox and OXE point to significant fuel savings compared to gas. Cox claims its 300-horsepower CXO300 offers roughly 30% fuel savings compared to its gasoline equivalent, while Mahendra says the 300-horsepower OXE 300, due to enter production shortly, uses up to 42% less fuel than a comparable gasoline outboard."

This fuel efficiency results in greater operational range so boats can stay out on the water longer.

Diesel outboards also have the usual advantages of diesel engines, including endurance, torque and flexibility. Though the price advantage goes to gas-powered outboards, one can make up the difference by comparing the life cycle costs of each and in most applications this would be fairly even.

Stories We Liked -- Are You Still Hearing These Common Myths About Diesel?

This week our editors are on vacation, so we're posting our favorite stories worth repeating from the previous year.

One of the things every Internet junky knows is that there is a lot of information out there in cyberspace, as well as misinformation. On this blog our theme is always Diesel, and by that we don't mean Vin. On this topic there are new stories every day. There's also a massive backlog of archived stories that are still relevant. 

Here's a 2019 story from Hot Cars that caught my eye and is still totally relevant. The article by Goran Radanovic is titled 25 Myths About Diesel Engines That Simply Aren't True.

Radanovic begins with a little history of diesel engines and their development. The significant feature of this power plant design is the manner in which it generates combustion. Ignition is caused by the elevated temperature generated in the cylinder by mechanical compression, which results in the ignition of the fuel. It's a brilliantly simple concept based on an understanding of basic scientific principles. 

Despite their proven track record of more than a century of service, a number of myths have grown up regarding diesel power. The author actually cites 25 here. I'll note a few of them and then send you directly to the source at Hot Cars.

1. Myth: Diesels are the largest cause of air pollution.

When you see that black smoke billow you do have to wonder how this isn't true. But the reality is, there have been great strides taken to clean up diesel. The industry has come a long, long way. Remember how much black smoke steel mills spewed a century ago? You don't see any of that today, and these engines now a different from olden times.What I find interesting is that there is such as thing as being too quiet. I vaguely recall reading last year that the EV cars are so quiet they are dangerous for blind people who can't hear them coming. 

2. Myth: Diesels are loud.

That, too, has changed. "Common-rail technology made diesel engines almost as quiet as gas engines," he writes. 

3. Myth: Finding diesel fuel at the pump is impossible.

Not sure why anyone would buy this myth. The infrastructure for diesel is everywhere. I will tell you what IS true. You're not going to have as easy of a time finding charging stations for your Tesla. At leas t not yet.

4. Myth: Diesel engines are only good for towing.

Towing is just one of the advantages of diesel engine technology. Reliability and longevity are additional benefits.

5. Myth: You can't tune a diesel engine. 

This seems strange. If you've ever witnessed or been part of a dyno competition you can see that it's all about tuning for maximum power. According to Radanovic, "The truth is that diesel engines have withstood better tuning than gasoline engines."
