Kerry hit some good points.

I'll add in that Diesels require more oil capacity due to keeping the turbo lubricated. They also use the engine oil to drive up the fuel pressure at the injectors (powerstroke fords see around 2000psi of fuel pressure at the injectors) The added capcity also assist in the oil taking longer to breakdown which in turn makes the suggested oil change mileage intervals extend to 7500 miles
