<< Amsoil v. Mobil 1 thread?  >>
That was my tread, but for the for some reason i can't find it in the arcived messages :|
But anyways for the most part, the conclusion was, Mobil 1 and Amsiol are pretty much the best sythetics  that you can get.  Right now, I'm using Mobil 1 in my 2001 Sunfire w/ 5 speed.  I could acually "feel" the difference in the car after I changed for a synthetic.  Mobil 1 you can go around 5k to 6k per change.  I think I may be changing to Amsoil though, I'm go'in to be starting co op(hopefully) and I'll be putting a crapload more miles on the car, and you can go somewhere up to 25,000 miles per oil change but you have to change your filter after the 12k mark.  
In my opinion, if you have a little extra money and really wanna take care of your engine, go for Mobil 1 or Amsoil.  The feedback that I got from my thread and talking to 5 or 6 mechanics, go for the Amsoil or Mobil 1.  Which one you choose is pretty much personal preference.  With the better "feel" that I got from my car, I'm definately not going back.
