Hello, I have a 1991 BMW 525I series and have used Lucas oil stop leak and it did not work. If I used your rear main sealer would it work on my car and how many days would it take before I noticed that I would no longer see oil leaking. Thanks Bill D.
I just bought a bottle of blue devil head gasket sealer that said for use in 4 and 6 cylinder engines and my truck is 8 cylinders. Can I still use this product on my truck or do I have to get the other bottle with the yellow sticker
