Car & Driver Puts 2021 Chevy Suburban Diesel to the Test but You May Have to Wait to Get One

A week ago Car & Driver published an enticing review of the 2021 Chevrolet Suburban. The story, titled Tested: 2021 Chevrolet Suburban Diesel Should Be the Default Choice, gave a mouth-watering review of the 2021 Suburban, went so far as to suggest that all Suburbans should be powered by the diesel Duramax 3.0 engine. 

Automotive journalist Ezra Dyer describes how "the 3.0-liter six is perfectly adapted to Suburban duty. Its 460 pound-feet of torque arrive at only 1500 rpm, imbuing the 6272-pound behemoth with an air of nonchalant muscularity in real-world driving."

The diesel Suburban is not a race car, and you wouldn't expect it to be with a 277-hp engine, but it does jump from zero to sixty in a quick 8.4 seconds, and adequate pace for merging into traffic.

For Dyer, one of the high points on this SUV is its stability. It's smooth. "With that luxurious 134-inch wheelbase and four-wheel independent suspension, the Suburban glides imperiously down interstates, whether perched on its base steel springs or the optional air suspension with magnetic ride control," he writes of the full-sized SUV. 

The noise volume on this car -- or lack of it -- is noteworthy. When cruising along at 70 mph, the volume is equivalent to a Lexus ES350. And of the noise you do hear, most of it is wind and tires, with only a mild hum coming from the straight-six on the other side of the firewall.

When it came to the low points of this story, there really wasn't much to say. The Suburban gets decent numbers when it comes to city and highway driving. And the diesel can tow around four tons if need be. Other "low points" read like high points, with the only real gripe being that the diesel Duramax is not the default engine and you have to request it. 

You can read the full story here. There are lots of photos.

And now the bad news. If you are one of those who was sufficiently enticed into considering this as your next purchase, hold your horses. The Fast Lane Truck (TFLTruck.com) just broke the news that GM is temporarily stopping production of the 3.0 Duramax Diesel Inline-6 engine due to a parts shortage.

These Covid-era supply shortages are more than annoying. Chip shortages have caused the automakers plenty of headaches already this year. Over the weekend GM confirmed that this will impact the Chevy Silverado 1500, GMC Sierra 1500, Chevy Tahoe, Chevy Suburban, GMC Yukon and Cadillac Escalade.

Fortunately it's only a temporary setback. They promise to resume production as soon as possible.   

A Tribute to Diesel Farm Trucks and Their Kin

Photo by Matt Palmer on Unsplash

Here's an interesting article about Farm Trucks that was originally published in the Idaho edition of Ag Proud. The article by Allen Schaeffer, Executive Director of the Diesel Technology Forum is packed with information about this very specific application of diesel technology. The DTF is a not-for-profit organization dedicated to raising awareness about the importance of diesel engines, fuel and technology. The article is titled simply "What is a farm truck?"

Now you'd think everyone would know this, but when you read a little further you'll see that nothing is really as simple as it seems, especially when you get into legal matters and governmental explanations. 

Wikipedia describes a farm truck as "a vehicle designated for agricultural use, and may include anything from small pickup truck or even vehicles fashioned out of old parts, to class 8 eighteen-wheeler trucks."

Mr. Schaeffer's definition is more detailed: "According to the U.S. DOT Federal Motor Carrier Safety Administration (FMCSA)a farm vehicle is one that is: registered in a state with a license plate that identifies it as a farm vehicle … transporting agricultural products, livestock, farm machinery or supplies to or from a farm, and is not used in for-hire motor carrier operations."

The next sentence amplifies the initial definition. "Some states in the United States have a special registration for farm trucks that includes restrictions such as distance the vehicle may travel from the farm." This is where it gets complicated because some states have restrictions that others do not. There are also licensing issues. That is, certain vehicles require a Commercial Drivers License (CDL) in some situations and in others you do not.

In 1900, when the nation was 60 per cent rural, trucks didn't exist yet. Horses did all the grunt work of bringing produce to market. Today, all the horsepower come from under the hood. 

"The most iconic farm truck of course is the pickup truck: half-ton, full-size, extended bed, crew cab, dually, fifth wheel – the list of options and configurations is near endless," he writes. And for the past few decades the Ford F-150 has been the leader of the pack.

Just how much of a leader Ford has been was revealed in a Great American Truck Survey involved 2000 truck owners. Here are some facts that you'll enjoy if you are a loyal Ford fan.

--More than 3,000 TV shows mention Ford trucks.
--Over 180 songs also mention Ford trucks.
--79% said they would give up alcohol for an entire year rather than give up their truck.
--15% have tattoos that reference a truck or their favorite brand.

Farm trucks usually arrive on the farm after undergoing wear and tear by a previous owner or two. Because these vehicles are used seasonally, they often don't accumulate as many miles as daily drivers. Schaeffer spends time explaining that despite limited season use farm trucks still require maintenance. Brakes, filters, fuel systems all need attention. The importance of fuel stabilizers and cold-weather additives can't be ignored either.

The article goes into detail regarding the tendency to overload trailers and truck beds when bringing in the sheaves, or whatever else you're harvesting. Be careful. Old equipment can suffer in those situations. A groaning engine is one thing, breaking a belt is much bigger issue. Having a tire go flat while carrying a heavy load across the middle of nowhere is something you just don't want to do. In fact, the author experienced that situation himself once. It wouldn't surprise me to learn that he's been warning farmers ever since, as he did here.

Diesel enthusiasts, he notes, received some uplifting news entering the 2021 season. It is the first year that all of the big three manufacturers offered a diesel engine option on all full-size pickup trucks. Pickups are today's workhorses for farmers, no question about it.

His closing statement shows how much the author is a real truck guy. "The FT/farm truck designation has real meaning – both to those behind the wheel and those in the motor vehicle enforcement world. But one thing is for sure, we all love (and need) our trucks, farm or otherwise."

First Impressions: Whacked Out Diesel Rat Rod

See full screen photo and videos at The Drive.

A rat rod is a custom car with a deliberately worn-down, unfinished appearance, typically lacking paint, showing rust, and made from cheap or cast-off parts. In the rat rod scene the cars are as unique as snowflakes, each reflecting the eccentricities of its owner. That's what makes the rat pack so much fun. 

One other common denominator in this automotive genre: every vehicle has a story. 

Last week Caleb Jacobs of The Drive posted a story about a very cool Chevy drag truck named Burnie.  The name itself is a story, which we'll return to shortly. 

The truck's own, Robert Berry, has his sights set on becoming the fastest 2-wheel drive, street legal diesel truck in the world. Yes, that's an ambitious goal, but he's clearly marking a path to get there, learning the ins and outs of nitrous, and all the other tricks he can from others who have been in active pursuit of diesel drag records. 

The opening line in Caleb Jacobs' story on Burnie is clever. "Old trucks should never die—they should just be repurposed," he writes, and then admonishes us each to do our part to keep cool old trucks from being turned into scrap.

The aim of this story, besides highlighting features of a very cool truck, is to dissect what it takes to create a top-notch record-breaking drag truck. The world, Jacobs says, needs more eight-second trucks. Here is what Berry Builds has done with Burnie.

The power plant is a 5.9-liter Cummins built by Industrial Injection, a diesel shop located in Utah with a gold star reputation. "It runs a compound turbo setup with an 88-millimeter Garrett GT55 on one side and a BorgWarner 7378 on the other, helping it pull 1,283 horsepower on a dyno without nitrous." That's a pretty solid foundation as a starting point, but add in the Nitrous Express system with 46-136 and you've got a screamer. "Pair that with Burnie's dual FASS Fuel CP3 delivery systems," Jacobs adds, "and it's getting plenty of sauce to fly down the strip."

The name Burnie has a double meaning. Drag racers love doing the burn-out thing. Builders, however, dislike it when things catch fire inside the truck. Evidently there were rats nests in the truck that caught fire when Berry Builds first started working on it. (Remember, this was a 1945 Chev that must have had a stretch of downtime before its resurrection and renovation.)

One of the main obstacles to achieving record-setting paces on the track is traction. This rod has a Moser M88 rear end with 45-spline axles designed to harness the power which has been channeled through a Goerend-built 48RE tranny. Even so, they've had trouble getting their 17-inch-wide Hoosier drag slicks to hook up. Sigh. 

Burnie had a "best time" of 8.90 seconds at Tulsa Raceway. Jacobs says the time could have been better had the windshield not been sprayed with fuel while rocketing down the track. 

It's noteworthy that Burnie is street legal. Every effort is being made to get the truck down into the 7s, but whether successful or not, this rod is guaranteed to turn heads wherever it goes.

Diesel Inspection: National Brake Safety Week

I'm not sure how these things get started but it seems like there are plenty of them. National Pollinator Week celebrates the work of bees. National Dog Week, the last week in September, celebrates man's best friend. 

This week is Brake Safety Week, emphasizing the importance of brake systems and components during roadside inspections across North America. Here's a press release from Champion Brands followed by a link to a Fleet Owner story about this important topic. 

This Week is Brake Safety Week

You may want to take time to check your vehicle. The Commercial Vehicle Safety Alliance's annual Brake Safety Week is in full swing. It’s when law enforcement inspectors across North America will be looking for any commercial motor vehicles found to have brake-related violations that might place them out of service.  

During last fall's brake inspection blitz, more than 5,100 commercial vehicles were placed out of service because of brake-related violations. In addition, brake system and brake adjustment violations accounted for more vehicle violations than any other vehicle violation category, accounting for 38.6% of all vehicle out-of-service conditions. 

What can you expect if pulled over for inspection?

Law enforcement officers checking brake systems will look for:

• Loose or missing parts
• Air or hydraulic fluid leaks
• Trouble-indicator lights on the dash, including antilock brakes
• Worn linings, pads, drums, or rotors
• Mismatched air chamber sizes across axles
• Warning device functionality (such as antilock braking system indicator lights)
• Proper brake adjustment
• Brake hoses and tubing condition 
• Measure pushrod stroke to ensure brakes are properly adjusted.

“While you are at it, it’s a good idea to either top up or flush your brake fluid,” suggested Karl Dedolph at Champion Oil.  “Brake fluid is an important component in any hydraulic braking system. The fluid is subjected to hundreds of pounds of pressure but also needs to lubricate rubber components in the master cylinder, wheel cylinders, calipers, and hoses. In addition, brake fluid has corrosion inhibitors that keep the bores of hydraulic cylinders from rusting and pitting.”

 

“Most of today’s brake fluids are made of polyalkylene glycol, which is hygroscopic, meaning it absorbs moisture. The absorption of water prevents “pooling” of the absorbed water in the brake system, where corrosive acids can form and make the components deteriorate.  Water in a brake system will also cause fluids to freeze or boil faster.”

 

“Champion DOT 3 Brake Fluid is typically recommended for cars and trucks prior to the mid-1990s, but DOT 3 brake fluids still makeup a large portion of service fills in newer vehicles. DOT 3 brake fluid has a dry boiling point of 490 degrees, which is fine for brake systems with large brake drums and thick disc brake rotors, where brake heat can be easily dispersed. It has a viscosity of roughly 1500cSt at -40 F. Exceeds the specifications of Federal Motor Vehicle Safety Standard #116 and SAE J1703 for DOT 3 brake fluids.”

“Champion DOT 4 Brake Fluid is recommended for most disk brake vehicles and is also a poly-glycol base. DOT 4 has a boiling point of 494 degrees F., and it is rated at a viscosity of 1800cSt at -40 F. This DOT 4 brake fluid differs from DOT 3 due to the ability it has to chemically scavenge water, reducing the rate at which performance deteriorates when the fluid is exposed to humidity in service. Exceeds the specifications of Federal Motor Vehicle Safety Standard #116 and SAE J1704 for DOT 4 brake fluids," added Dedolph.

The Four Key Lubrication Tactics to Extend Diesel Engine Life

Model diesel engine. Luc Viatour, Wikimedia Commons

One of the benefits diesel engines offer over gasoline engines is longer service life. That being said, it's useful to know that there are steps you can take to get the maximum life from your engine before it needs its first overhaul. Here are some things you can do drawn from an article in Machinery Lubrication titled "Lubrication Tactics to Address Diesel Engine Life."

The article is essentially a practical outline of matters to address in answer to the question, “Are there any specific lubrication tactics that can help extend the service life (overhaul interval) of a diesel engine?”

The answer is yes, and the author proceeds to outline the four "rights" of lubricant application: 
The Right Lubricant
The Right Amount
The Right Component/Machine
The Right Change Interval.

It's a clever way to think about lubrication and it applies to all things that need lubrication, whether in the form of oil or grease. In this case we're talking about oils for diesel engines.

The first action suggested is to select a high-performance oil, rather than the one with the lowest price. This can be synthetic or mineral de[ending on the engine's requirements. 

Engines are designed to hold a specified oil level, so using the right amount of oil is important. This oil should not be mixed with other products, the author states. The specified oil is designed for a purpose. Its effectiveness can be altered through mixing with assembly lube or other products.

Because lubes age over time and during service life, they need to be replaced from time to time. This article notes that the "when" for changing oil should be not based on a time period or mileage limit. Rather, oil should be changed when it is ready to be changed.

To know the "when" you can perform oil analysis or utilize online sensors. This kind of monitoring will help you optimize the oil's use which still protecting the engine.

After explaining the four "rights" we are reminded of the need for proper filtration so that the oil is free of contamination, whether solid of liquid. The author suggests that the oil should be filtered before being put in the engine, and maintained in this condition using high-quality filters.

Many people use by-pass filters which take a portion of the oil out of circulation to continuously filter more slowly and more effectively before reintroducing to the oil stream. Premium air filters are also recommended because a majority of debris that gets into the oil is sucked in through the air.

Periodic oil analysis is the most effective way to monitor contaminants in the oil, whether fuel, glycol or soot, as well as other particulate matter. By this means you'll know when corrective actions need to be taken.

Because water contamination can be an issue in many machines the author recommends keeping your lubricants dry. They should also be kept cool, because the higher the operating temperature the shorter the lubricant life. For maximum service life, pay attention to operating temps.

If you're really looking for the most out of your engine life and lubricant performance, the article notes the importance of several additional variables: good training for your maintenance personnel, good procedures, the right tools, communication and team alignment. You may  even consider a pre-lube system. And last, but not least, use a high quality fuel and a periodic engine flush.

If it seems like a lot to consider, it's good to know what is possible.  This is the "white glove" treatment, if you know what I mean.  Read the original story here.

Why Does Engine Oil Break Down

Rumors of a Diesel Tundra and Other Toyota News

The 2022 Toyota Tundra: Ready to Rumble

They say we're not supposed to believe everything we hear. Nevertheless, there are times when rumors have a sticky quality that makes them hard to simply ignore. One of the hot ones creating buzz this summer has to do with the possibility that Toyota will be producing a diesel Tundra for the U.S. market. This morning we'll explore this idea a little bit.

At the end of July CarBuzz published a story titled Toyota Ready To Reveal A Diesel Tundra? Sebastian Cenzo's story doesn't say outright that this is happening. The subhead reads, "We have a suspicion that a diesel Tundra is in the works."

How well founded is this suspicion? Though Toyota sells no diesel-powered vehicles in the U.S., it seemed suspicious to some when Toyota posted a video about how a diesel engine works. In fact, this video -- How Does A Diesel Engine Work? -- is one of the best I've ever seen with regard to the difference between a gasoline and diesel engine.

The CarBuzz reasoning goes like this. Toyota has been posting a lot of images and information about the Tundra, showing off all its new features, stoking demand for this beefy pickup. The only thing they had not revealed is what kind of engine options it will have. And then the video comes out regarding how diesel engines work. Is this just happenstance?

On August 16 Tom Quimby of Equipment World picked up the thread. His story goes even further. It's titled, Viral Toyota video has fans hoping for a diesel Tundra, Tacoma. Quimby goes even further than Cenzo, suggesting that we might see more than just a Tundra powered by diesel. He begins his piece with this:

A recent diesel engine video released by Toyota on its YouTube site has gone viral and has fans hoping that the automaker will bring an oil burner to the U.S. and make it available in the Tundra, Tacoma and 4Runner.

It apparent that these speculations are based on rumor since there has not, as yet, been any official announcement. Fans of Toyota quality are simply connecting a few dots, and hoping they're accurately reading the tea leaves.

The Equipment World piece notes that the Toyota has been slowly rolling out the Tundra "reveals" since May. Powertrain speculation has been simmering for some time. It will be a pretty special moment when Toyota lifts the hood.

In early July Tim Esterdahl recorded his hunches in a story for Pickup Truck Talk. His story makes note of the patent filed in July 2020 for a new iForce Max engine.

As early as June we saw the First Official Look at the 2022 Tundra. Lots of details were included in this story at TFL Truck (The Fast Lane). It's a muscular look for sure. Nothing timid here. Despite all the details, it remained unclear as to whether this truck ran on diesel power.

Which brings us to today's latest Toyota news. The  Wall Street Journal announced that Toyota is cutting production in Japan by 40% in September and 40-60% in North America this month because of the global semiconductor shortage. For and GM have been indicated their plants will experience more downtime as well at several factories. 

One thing is certain in these uncertain times: you can never tell for sure what will be next. 

Here's the Toyota video that ignited our imaginations: Engines 101
