There's a reason that ships, trains, semis, tanks, big generators, bulldozers, crains, farm equipment.............. ALWAYS have diesel engines in them. They tried putting gas engines in semis in the 70's and 80's and it was a disaster. Diesel engines have to be made more stout because of compression and have much better eternal components and have fewer moving parts. To have a diesel car in Europe with a million miles on it is a pretty normal thing, in the states it's rare to find a gas engine with a million miles. Think about it!
