I was thinking about making the switch from my typical Chevron Supreme 10W-30 to a full synthetic equivalent for the remainder of the life of my engine. What do people think of running full synthetic in this engine? Does it seem to help the engine run better or has anybody noticed that their oil stays cleaner longer? I have a 92 XJ with 209,000 miles and it does not leak oil.
