Laughing Coyote Posted February 20, 2015 Share Posted February 20, 2015 Once again I'm requesting some knowledge from my fellow car guys (and gals). I wanted to know what is a good break in oil with a high zinc level so when I get ready to fire up the engine I don't wipe out the cam lobes and flat tappet liffters.

Guest DriveAG Posted February 20, 2015 Share Posted February 20, 2015 Lucas non synthetic 50wAnd here I always thought that break-in oils are for tight engines so low viscosity is used. Brad Penn makes a special break-in oil at 30 weight for non-catalytic engines. They also go as low as 0W-30 on their general line. Link to comment Share on other sites More sharing options...
vintagerodshop Posted February 20, 2015 Share Posted February 20, 2015 the origional poster did not specify what era of engine he was working on. we mostly work on on pre 30's cars and found the 50 weight works well on the older stuff. Link to comment Share on other sites More sharing options...
Laughing Coyote Posted February 21, 2015 Author Share Posted February 21, 2015 The car is a 1961 Mercury with a 352 engine. I guess I should have been more specific. Link to comment Share on other sites More sharing options...
