Look up Shaeffers racing line of oils! It is designed to run in alcohol motors so its fairly stout motor oil! I nust bought a case of 12 for around $92 or $93 shipped! Contact Don "sully" Sullivan he is the rep that sold it to me. Stand up dude he will take care of you. His cell # is 219-484-7418. This product is proven!! He will provide you the technical data sheet of the contents of oil. As a matter of fact he encouraged to spread the word!! Another contact is his e-mail at [email protected]
