I like what I read about REDLINE and the formula and chemistry,

http://www.redlineoil.com/products_motoroil.asp?productID=45&synthFlash=1&subcatID=14

seems to have larger molecules that do not breakdown, I believe that is what got rid of my noise, I don't like engine flushes, you never know what they remove that was holding something together and then where it lodges, Change to REDLINE is a cheap try. Let us know results
