Thanks to the rising costs of (decent) diesel fuel and the high cost of (decent) diesel-specific replacement parts and fluids, modern diesel vehicles can actually end up being quite a bit more expensive to maintain than similar gasoline-powered vehicles. Ouch!

That said, while most gas engines are intended to last at least 200,000 miles on average, a diesel truck that is well-maintained can potentially last 350,000 to 500,000 miles. Those used mainly for highway driving and carrying minimal loads will typically get closer to the top-end of the range.

Gas Trucks – Resale Value. Because diesel trucks last longer than gas trucks, they depreciate at a slower rate. That means their resale value is generally higher than gas trucks.
