It’s normal for your car’s gasoline engine to run for around 200,000 miles before it needs a serious overhaul, or you need a new vehicle. But diesel engines can continuously run for an impressive 1,000,000-1,500,000 miles before needing any major work.

Why are gas engines better than diesel?

Diesel fuel simply packs more energy in every gallon than gas fuel, which makes it more economical overall. Diesel engines are still more efficient than gas engines, but less so for those who are mostly engaged in city driving. For most U.S. consumers, diesel fuel and gas fuel cost about the same.

Can you put diesel oil in a gas car?

Why diesel engines have more torque?

The higher turbo boost pressure, high compression ratio, and greater heat content of the fuel all add to the generation of cylinder pressure that is substantially higher than in gasoline engines too, but it is this continued injection of fuel that really makes the big torque numbers for diesels.

Is it bad to drive a diesel short distances?

Also known as “diesel car city driving”, you want to avoid doing this. Driving at low speeds and short distances clogs up your Diesel Particulate Filter (DPF) quickly. The effect of this is much slower if you have a high annual mileage (think 10,000+ miles per year) or drive mainly on motorways.
