That is the key and only UOA will tell you if your oil is working. It took me 8 months and 3 diferent oils before I found one that actually works well in my motor.
[IMG]Chrysler, Ford and Dodge, in a MATTER OF FACT the Dodge racing team uses Motor Silk for three years now as does many NASCAR teams.[/IMG]
I believe this to be a blatant lie. Valvoline SynPower does smooth out the motor and quiet your valves and is the only aditive I would use. That said in my car M1 T&SUV works better actually with no additives.
