A short time ago I posted about loud piston slap knock/rapping on cold weather start up till engine warms up.
Seems to be a pretty common problem with the 3.5L.Though my other car with the 3.5L doesn't have a problem...yet.
Was very loud with Amsoil 0w30.I went back to conventional and it's there but much quieter.
I like using synthetic oil.
Would the moly in Schaeffer's 5w30 oil with all that moly be as quiet or quieter than conventional oil in my 3.5L RX 350?
