Just thought I would pass this along. Today I talked to the 3rd candidate for rebuilding my '69 small block and he told me he wouldn't build the engine without roller cam and rockers because of the lack of zinc in the oil. I told him that I use Rotella which has zinc and he told me that "...the government does not allow any zinc in any oil sold to the public. This includes Rotella." I just got off the phone with Shell tech support and was told that as long as I am using a multigrade Rotella, there are 1200 PPM of zinc. Needless to say I don't think I will be using this shop. As usual, Duke is right!
