Hey people just my .02 cents. but I have been jaround cars for a while and working on my own, even built a few of my own. and as far as I'm concerned synthetic oil should not be used until after at least the 1st oil change. (I wait until about 9000 miles to switch over.!) The reason I do this is because synthetic oil has such a great lubricating function that it does not allow the rings and some other parts to break in correctly. this is what i've read and been tolld numerious times. Just a heads up and it is only a suggestion! the car came with non-synthetic so it wouldn't hurt to leave it that way for a little while longer anyway!
