Does diesel engine require more maintenance?
Since diesel engines tend to have a longer lifespan than their gas counterparts, they may benefit from more frequent cleaning. After all, when a vehicle navigates longer distances and more challenging tasks, dirt and dust have more opportunities to collect on its engine.
Why do diesel engines last longer than gas engines?
Another reason diesel engines last longer than gas engines is due to the fuel that they burn. Diesel fuel is a type of distillate fuel that is essentially produced from crude oil, which gives diesel engines slower cylinder wear than gasoline engines. … The leaner air to fuel ratio helps cool the EGT’s.
Are diesel engines reliable?
Pro: Diesel Engines Are Known for Reliability and Longevity
Because they run at lower revolutions per minute (RPM), diesel engines wear down more slowly than gasoline engines. They’re also built tougher with thicker cylinder walls and sturdier parts, including the valves, pistons and crankshaft.
