Re: Engine Break In
The valvoline vr1 is not a high zinc content oil they make a oil called Valvoline Conventional racing oil that is suitable and is only sold through NAPA p# VV851. After researching this subject we've found that anything with the API seal on the bottle does not contain added zinc. Brad Penn, Q Racing , Valvoline conventional Race , and Joe Gibbs oils are the ones so far that we have found to work as break-in oils also stated on the bottle not street legal. Also as of Jan 01 rotella will reduce the zinc content of their oil to match 2007 emission laws.
