Change your oil how you wish. We lab the oil on all our trucks. We just found out we had an injector going out due to oil analysis.
Diesel and gasoline engines are two completely separate technologies and do not provide data that is useful for the purpose of oil change interval comparisons, not to mention your trucks see mostly highway miles, there is no way a diesel Peterbilt traveling cross country compares to a gasoline-driven quarter ton pickup truck that sees all stop-and-go city driving, not to mention lawn mowers.

You can't run synthetic for 85,000 miles in no quarter ton gasser and I don't care who you are, it will most likely cause engine damage over time and at the very least performance losses that will cost you in terms of fuel economy alone.

And in terms of hours, we were talking gasoline-powered lawn mowers.
