Hello, I didn’t find anything on the subject with the SuFu, so I’m going to open a new thread. How long does a Porsche engine and transmission (especially Turbo, GT 2, GT 3) stop running on the race track with good maintenance? How often should you change the oils on the race track? I’m already aware that there are probably both extremes, but some may have some experiences. MfG! Packaget
