The only reason why diesels cost more is because they are engines that are designed to last three times longer then a gasoline, so they are built heavier. They only cost more if something breaks down like a fuel pump. It also cost more for an oil change, but you can go up to sixteen thousand miles before you change the oil on a Caterpillar engine for example. While a gasoline engine you have to change the oil at least every six thousand miles. Spark plugs, rotor, distributor cap and wires at least once at one hundred thousand miles. Diesel does not have any of that junk.
I have sixty thousand miles on my diesel engine now and the only problem I had was a Huei lift pump that was still under warranty.
I will still take a diesel over a gasoline engine any day and I have had both.
