oil change question
Mobil 1 5W30 is not the greatest oil for the LS1; it is too thin for a 30wt, and the LS1 really prefers a thicker oil.
Run a search on 'german castrol' or Amsoil European forumla, or even Redline 5w30 (thicker 30wt than the M1 5w30)
If you live near an Autozone, chances are they carry Castrol Syntec 0W-30. Awesome oil, and best for this car.
