Now lets talk about pros and cons of diesel engines or diesel trucks. Some of the pros about a diesel truck is that they are very efficient and most of them on a good day get about 25-30 miles to the gallon. Diesels also can deliver as much or more fuel economy than traditional gasoline-electric hybrids, depending on the models involved and whatever rapidly developing automotive technology achieves. Diesel fuel is one of the most efficient and energy dense fuels available today. Because it contains more usable energy than gasoline, it delivers better fuel economy. Diesels have no spark plugs or distributors. Therefore, they never need ignition tune-ups. Also diesel engines are built more ruggedly to withstand higher compression. They usually go much longer than gas-powered vehicles before they require major repairs. Mercedes-Benz holds the longevity record with several vehicles clocking more than 900,000 miles on their original engines! You may not want to hang onto the same vehicle for 900,000 miles, but longevity and dependability like that can sure help with trade-in and resale values. Most if not all diesels last a lot longer then a gas motor just because of the way they are built. These trucks are made to run for close to 500,000+ miles just because of how they are made and how they can make power and how they run.
Some cons about diesel engines. Diesel fuel used to be cheaper than gasoline, it now often costs the same amount or more. Diesel fuel is also used for commercial trucks, home and industrial generators, and heating oil, so as demand for diesel passenger vehicles grows, the price of diesel fuel is likely to continue to rise because of competition from those other users. Although diesel fuel used to be cheaper than gasoline, it now often costs the same amount or more. Diesel fuel is also used for commercial trucks, home and industrial generators, and heating oil, so as demand for diesel passenger vehicles grows, the price of diesel fuel is likely to continue to rise because of competition from those other users. Diesels still need regular maintenance to keep them running. You have to change the oil and the air, oil, and fuel filters. Cleaner diesel fuels no longer require you to bleed excess water out of the system, but many vehicles still have water separators that need to be emptied manually. Without you maintaining your truck it could end up not good, either your motor would blow or something else bad.
