They typically deliver 25 to 30 percent better fuel economy than similarly performing gasoline engines. … PRO: 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.
Are diesel engines more expensive to maintain?
Diesel maintenance is cheaper overall, since diesel engines have fewer problems than gas engines; but diesels are more expensive when they need repairs. Diesel maintenance generally will not cost you more than for a gasoline powered version, depending upon the type of diesel car that you have.
Are diesel engines more efficient than gas?
Diesel Engines. One of the most important differences between gas and diesel engines is the thermal efficiency of diesel engines, or the work that can be expected to be produced by the fuel put into the engine. A diesel engine is about 20% more thermal efficient than a gas engine.
What is considered high mileage for a diesel?
Generally speaking, diesel trucks are sold with higher mileage than the typical used vehicle. It is not uncommon to see a used diesel truck for sale with over 200,000 miles on it. Granted, diesel engines typically have better reliability than a gasoline equivalent, but high mileage remains a concern.
Do diesels need to be driven hard?

Why you shouldn’t buy a diesel car?
Although diesel-engined cars emit more particulates than petrol ones, their CO2 emissions are generally lower. It’s also important to note that older diesels have far higher particulates and CO2 emissions than newer ones and that the European Union has been tightening up on emissions since 1992.
What is the average life of a diesel engine?
But diesel engines can continuously run for an impressive 1,000,000-1,500,000 miles before needing any major work. In fact, a well-maintained diesel engine can be on the road for 30 years or more.

Why do diesel engines cost more?
The heat of the compressed air lights the fuel, explains Raman. So, the high operating temperature ensures that the diesel enjoys premium treatment when it comes to component quality. Along with expensive components, most oil burners also come fitted with turbochargers and this increases the overall price as well.
Why diesel engines have more mileage?
Petrol vs Diesel Mileage
The mileage of the diesel engine is more than that of a Petrol engine. A diesel engine does not need a spark plug and thus has higher compression. This makes the diesel engine utilise more fuel as compared to a petrol engine.
