Personally, I think choosing the best is a more difficult task than identifying the worst. We may have built in biases regarding which features are of greater value to us personally. As we've written about before, it depends a lot on what you're using your truck for.
On the other hand, picking the worst is much easier. Why? Because the bad trucks, like those selected by Riley, the author of this piece, have a reputation. We're not talking about "Friday trucks" or "Monday trucks" where assembly workers are distracted or foggy. We're talking about bad engineering.
The one positive about some problems is that it gives aftermarket engineers an opportunity to create fixes for some of these mistakes. Not all design flaws are that easy to resolve however. Which leads to our story.
The title of the piece is 8 Best Diesel Trucks You Can Buy & 4 of the Worst.
The article begins with the basic reasons why people buy diesel trucks. First, they're workhorses. If you're towing a boat, ATVs, a camper trailer or hauling bricks, you know the importance of having equipment that's up for the task.
Riley's concise description of the benefits of diesel is worth memorizing. Diesel engines "get better fuel economy, are often easy to modify with aftermarket parts, and, when properly maintained, will basically run forever. This makes them a great deal if you are looking for a used truck."
All this is a plus for diesels, but there's a minus, too. A well maintained, low-mileage vehicle can cost a pretty penny. That's OK with some of the best trucks, and totally not OK if you select a clunker.
That is why this article was written, to help us avoid purchasing a truck that has little more value than a lawn ornament.
The Autowise article begins with the 8 champion selections, then flashes warning signs regarding the losers. I will discuss the worst first, and list the 8 trucks they have labelled "the best."
THE WORST
Here are the four diesel trucks that this article recommends you avoid. Sadly, these trucks that have helped give diesel a bad name in some circles.
Chevy & GMC C/K 5.7L (1978-1981)
Older folk are familiar with the Oldsmobile debacle in which GM dropped a 5.7L diesel engine into an Olds. It went down in history as one very bad decision. Ironically, GM took this same engine and decided maybe it would work in a pickup. Two wrongs don't make a right. One problem was that this particular engine was a gas 5.7L converted into a diesel. There were other problems as well, Riley writes. Ultimately, the only thing going for this truck is the vintage look. Buyer beware.
Chevy & GMC C/K 6.2L (1982-1993)
GM learned some lessons by this point in time and decided to exit the diesel engine building business. They turned to a neighbor, Detroit Diesel, to undertake this task. Unfortunately, what they delivered was a 6.2L engine that looked like it should have power because of its size. Such was not the case. The 130 horsepower it delivered is only 40 hp more than today's Smart Car. The other problem this engine had was a tendency to leak oil from the rear main seal. Not good. To fix this issue required removing the tranny, and you can be sure that was neither easy nor cheap.
Chevy & GMC C/K 6.5L (1994-2001)
You'd think by '94 GM would have this diesel business figured out, but no. The turbocharged Detroit-built 6.5L had a new set of problems. It was also behind the curve with regards to its indirect injection and couldn't compete with the Cummins and Powerstroke engines of the same time period, engines with 50% more power. Add to this the mechanical issues and your best best is to avoid them altogether. Riley says, "Get a Duramax."
Ford Super Duty 6.0L Turbo(2003-2007)
The article tags this engine as "by far the worst modern diesel engine." The engine was so bad that there were legal battles between Ford and Navistar (the parent company of the Powerstroke.) The list of problems this engine had includes head gasket issues and catastrophic fuel system failures. To make matter worse, to do some of these repairs required removing the cab in order to access the parts. Yikes. Riley recommends avoiding this one as well and find a 7.3L Powerstroke. You will be much happier.
