Mobil super 2000 semi syth 10w-40 ran my forged on it for 7odd years for over 10k miles. Any time the engine is apart i check it all through and its uber mint inside!! Best oil to use imo. fully is to thin for these old engines imo.
Needs a turbo soon me thinks ;) just a basic td04 set up or ct9 hybrid maybe and tbh agree about them handeling better grants donkey gives my levin a damn good run for its money tbh!
