Hi everyone. Throwing this one out to more learned folks. Just got my dream car of a black s8 d2 4.2 v8 83kwith updated rims exhaust and a remap it's a beast. My ask is will the engine accept and benefit from a ptfe oil additive. It reduces friction etc etc on the engine so would seem to have a lot of benefits. My old v6 minded seemed smoother after adding it....or that could have been the placebo effect. Thanks in advance.
