I know that over 120 degrees constant use oil become usless but I'm wondering how I go about (or more importantly cost) of testing the oil in my engine. Does anyone know who does tests and what the results would tell me?
Just thinkintg I'd be interested to see the restults of my cars oil after just a few thousnad miles of hard driving.
