the oil change statement always makes me LOL, with a gas motor most people do an oil change every 3-4k miles and it takes 5-6 quarts and a filter. with my 5.9 cummins I was doing a oil change every 10k and that is 12 quarts and a filter so how is it more expensive, and the oil analysis showed the oil was still good to use so I could have pushed it longer.
I think the same thing, but it's not worth arguing it anymore.
