Oil & Filter IC SC R3

IMO supercharged R3s should have oil & filter changed more frequently than NA R3s. I just completed the first oil & filter change since my IC SC conversion at 3000 miles. Forced induction forces more carbon fron the combustion chamber into the crankcase (yes, some does get by even perfect rings). The carbon buildup at 3000 miles was enough to warrant the oil and filter change, and my tune is dead nuts on. SC R3s running the stock TTS tune may see more carbon as that tune is slightly rich.

No metal in oil or filter.

I'm presuming you ain't running Quaker State?
