How often do you change synthetic oils?
How often do you guys change synthetic oil. I have a '89 SC with 31,000 miles on her. I'm using Mobil 1 full synthetic 5w30 oil. I know regular oil changes at 3,000 miles, but synthetic oils in the Super Coupe can you go 4 - 5 -6,000 miles on the same oil? I've heard mechanics saying you can leave the synthetics oils in longer. Will this harm the Supercharger at all? How many miles should I leave it in? Thanks Rick
