i decided to switch from regular mobil to mobil 1 synthetic. my car has 106,000 miles, this is the first oil change it has seen with synthetic oil. The car idles a bit smoother, but i dont think the affects will talk place on the first change. My basic question is, is a car too old or does ever have too much mileage on it to begin using a synthetic oil?????? +----------------------------------------------------------------------+ To unsubscribe, put "unsubscribe" (by itself) in the subject and send to [EMAIL PROTECTED] or use the form at http://www.sentra.net/sml
