Hello everyone, my 67 camaro with 6 cylinder has been sitting stored for 15 plus years and not touched. When I get the engine running I heard todays oil is not compatible with the bearings due to zinc content and bearing failure will result . How true is this and what is the cure. Thanks in advance as I know I need alot of things to check before startup
Like Bethanne said, a good broken-in motor doesn't need lots of high-pressure additives, especially your good old straight six. If you were doing a fresh start on a flat tappet race motor, that's another story. But you will be A-OK with any oil.
Good luck and keep your 6-cylinder a 6-cylinder if you can!
