Hi eric !

It's a good question,i think it all depends on your perception about if your believe high mileage oil formulas really do the job it was design for;I recall driving my little GEO tracker with more the 100R & used regular oil & never had any issues.

All high mileage oil products just says it's design for the high mileage cars,but doesn't certainly explains whats differs from the regular oil products & they all cost the same price so i don't get it

I guess expert advice is the way to go to clear any doubts
