Red Line does have one approved oil; Professional-Series 5W30TD Euro Motor Oil. It is "Factory approved for API SN, BMW LL-04, Porsche C30, Mercedes Benz-Approval 229.51 and VW-Audi 507.00/504.00" However, it has more "Distillates, petroleum, hydrotreated heavy paraffinic" than PAO in its mix.they have good base stock, but their additive package is questionable and dont forget they are not API certified.
