How do I know if I have oil sludge
I just bought a 98 Trep with 88k which runs well, and is generally beautiful. I have envied you guys with your treps since the G1's. Anyway how can I check if I have oil sludge and if I do can I do something to fix it before it becomes a problem. I am starting to use Mobil one synthetic with a premium filter. Any suggestions will be appreciated.
P.S. This site is a great find.
