About 10 days ago I changed oil in my 91 Chevrolet K1500 and used a quart of Lucas Oil Stabilizer. I know that the value guides are bad and the Lucas has helped. Today, I heard about LiquiMoly Oil Saver. The videos I watched say it will help with worn valve guides. Can I just add it in with the Lucas?
