Rear Seat Delete Builder
I got my GTO on wed. Do they come with synthetic oil or regular?
The rings on the LS1/LS6 motors have proven to seat better with conventional oil. Waiting to switch to synthetic until after they begin to wear in will give you the best performance and longest engine life.CSiJason said:You should run the oil it comes with for the first few thousand miles or so. It helps promote a little wear which is necessary for quick break in of the engine. Or at the best, switch to semi-synthetic after about 1000 miles.
