When should I go synthetic

[STOCKMACH104]

I got 2500 miles on it now . Just wondering when some of you fellow Mach owners switched over to synthetic

[MACHMAN]

i went to royal purple at 3000 miles, you should be fine @ 2500. but after reading alot about oils, mobil 1 sounds just as good and half the price.

I use mobil 1 myself, no complaints here.

Which? 0w20 or 5w30 Which one is best @ my current milege @ 2500 or should go with conventional till I hit 5000 miles. :cool:

Which one is best @ my current milege @ 2500 or should go with conventional till I hit 5000 miles. :cool:You can switch now, I would use 5w-30 Mobil 1. The 5w-20 and 0w-20 or only for mileage purposes and do not protect as well.
