What all do you guys know about this stuff? Although not very popular, everyone you ask says it's hard to beat, and I know a few people myself that have excellent luck with it. Just wondering your opinions......

 

I only use Mobil 1 in my car.

 

i dont use it in my car, but have to in my work truck since my cheap boss will only buy that. i dont care for it. co-worker swears by it, but seems too thin, no matter what weight he buys. truck doesnt act right with it, but as soon as i pay for almost any other oil, runs fine. maybe just me tho.
