Hi guy's, just wondering what ppl think about this subject.
Fully synthetic oil is as far as i know the best oil for your car, what i'd like to know is if Mobile 1 is worth the extra $10-$15 over the other synthetic oil's like shell. With non-synthetic oil's you'd change your oil every 5-10k k's is that right? Is an oil like Mobile 1, good for more than that, say 15-20k k's?
Also what fuel do most of you use? Should i use premium all the time is it worth it, i heard it will give you a few extra K's per tank if highway driving so you would make your money back, which i don't drive highway but not stopping and starting all the time either, plus it's good for your injectors i think? BP i noticed has premium & some other advanced premium or something with 98% octane, it was $1.12 as opposed to $0.99 for ULP, what do you guy's suggest. I drive a 94 Fairmont Ghia BTW. Thank's guy's.
