[QUOTE="Racer X, post: 334258, member: 1934"] 5,000 miles here. Some Syn oil manufacturers recommend the same change intervals as conventional oil unless an extra filtration system is installed. Read the label etc. about that. With that said, you have the input of other forum members already. :thumbup: Racer Product research and development consultant to the automotive industry.
