(But then I also don't put big miles on it either, as I only have ~8K miles in 1.5 years from brand new.)
IF it had more capacity (like 6+ quarts), I
might be tempted.
Yeah, I have a 6qt sump. Hyundai specs conventional for 7,500 miles intervals in my 3.8. I do 6,000 just because it is all short city trips and I flog the poor girl like rental.
For my fleet, Fords get 5,000OCI and GM/Chrysler gets 7,500. No DI issues. The Fords are shorter because of the turbos and often they have a lot more hours than miles. So I will have 400 hours by the time I hit 5K miles. Lots of idling/low-speed use. The GM/Chrysler have a lot more highway use.
