Re: what oil should I use in my 53 Clipper?

Many of us here enjoy using Shell Rotella 15W-40 engine oil. The type of oil selected depends upon engine condition, driving habits, and climate. Many feel that with a worn engine a 20W-50 grade or even 50W will help with their oil pressure and consumption. The heavier grades place a strain on the oil pump and do not flow freely enough during start up before engine is warmed. A heavy grade oil will not cure your worn engine problems. I would say the heaviest straight grade to use should be 30W. All of the above in my opinion, that is. JWL
