Just a note to let you all know that Swift Performance keeps the Joe Gibbs Hot Rod oil in stock. It comes in two weights, 15-50, and 10-30. This product is one of the few oils still on the market with the proper levels of ZDDP. There have been some issues with using the current line-up of lubricants from the big name companies as they have quietly changed the formulas in their products, and newer vehicles do not need the same additives.
We recommend using the proper oil, rather than using an additive. This is because the additives are not always compatible with the products already in the oil.
