azquadz Posted June 27, 2008 Report Share Posted June 27, 2008 I know this question has been asked before but I couldn't seem to find the topic. Which oil are you guys using in your SGTs? 5W-20 which is stamped on the oil fill cap or 5W-30 which is displayed on the Shelby decal on the underside of the hood?
