Good stuff, had a pretty bad oil leak on my 08 Audi A6 caused by hardening of the o-rings on the VVT. Replaced those and added this on the oil change to be extra safe. Completely stopped the leak and honestly felt like it drives a bit better too. Will probably just use this on every oil change from now on.
