what motor oil company do you guys go with? have you actually seen actual proof of one motor oil company being better than the other? full syntec or regular? i heard that mobil 1 was good, but how would it do against other motor oil companis like castrol, and vavoline? i mean seriously, when it comes to over the counter oil that you can get at a local auto store, i think most of them are gonna have the same results if it has that api stamp of approval on it. some people stick with one company cause they think its slightly better than other companies, or because they say its better for their make, and model of car, but i seriously dont think it matters that much. anyone have their opinions, or proofs on this?
