If I only drove 600 mi in 6 months though, I'd sell the truck and get a bicycle!
Filters do not need pre filling either. Another myth.
Any of you ever had a vehicle or equipment that the oil filter was mounted horizontal on?
How'd ya get that one full, or half full, or any significant amount of oil in it without it running out?
I agree with you the 6 month thing is bogus, but they manual states "under no circumstances shall the interval exceed 6 months". Don't know what that's all about but sounds like a good way to get out of a warranty situation.
I also agree on the need to prefill the filter; not necessary IMO.
Soot and ash in the oil create acid plus there is some condensation forming. The oil doesnt go bad it started getting a low PH
