I'll run it until the oil life monitor hits zero (which is always around 7000 miles) so I should have my first UOA by around October or November.
Notice anything with it?
I only drove it about 15 miles since I changed the oil and I honestly don't notice a difference from Platinum at all. The engine is just as smooth as before, still has the slight valvetrain tick that all LS1 engines have and throttle response is the same.
