i switched to synthetic about two years ago in my 95 se and i will never use conventional oil again. i noticed that the engine ran quieter and the temp gauge use to be between the "n" and the "o" in normal, and now i am lucky if it gets to the "n." that and an increase in gas mileage convinced me to stay with synthetic. i would recommend this to everyone. peace.

95 contour se, lots of mods.
