Does anyone use an oil flush before doing oil change?
#76
Now you guys have me worried. My 2011 Carrera S sees a lot of track days and is a DD. I change my own oil and use Motul 8100 X-Cess which I buy by the case. I had my car at the dealer for some other services, and while there, let them change the oil and they used Mobil 1. I ran that longer than I should have based upon my own standards and then changed it using Motul. I sent the Mobil 1 to Blackstone for analysis and the report came back saying everything was good other than a trace of fuel most likely from normal driving. I've been at the track 5 days with the Motul and haven't seen any problems so maybe I'm just lucky. I'll might look into using a different oil after my supply of Motul is gone.
