10 Most Reliable Diesel Pickup Trucks You Can Buy Used

Gasoline-powered trucks have been a mainstay in the market, while diesel trucks have been looked down upon. But diesel trucks are becoming more popular by the day, because of the numerous advantages they offer. For one, diesel trucks tend to have higher fuel efficiency than their gasoline counterparts, since diesel contains more energy per gallon than diesel. Diesel pickups are about 20% more thermally efficient than gasoline, so they tend to have higher power and torque figures.



Furthermore, diesel pickups are usually more reliable and longer-lasting than gasoline. Since diesel engines are usually gear-driven, the possibility of components failing is quite low. Diesel engines are often constructed with heavy-duty materials that can withstand wear and strain. So, if you are in the market for a diesel truck built like a tank, you will find this article very helpful.
