Hi guys! I've searched this and other forums and found some relative info for other years and motors, but nothing specific to MY year and motor. It's time for an oil change. I've owned my '96 4.6L LX for almost one year. The oil change/tune-up was first thing when I got her... regular gasoline-engine motor oil. While calling around for the best oil-change deal today, I heard about something new to me... a combo regular/synthetic blend oil change. I have already tried to learn about the difference between the two and know synthetic is supposedly better for high-mileage cars. Also learned that you can't just "switch" from regular to synthetic, or at least you SHOULDN'T. Also learned some new cars come out of the factory using synthetic. My questions are these: 1) With 196K miles, should I be using synthetic? If so... 2) How do I safely make the switch?
