I've used Royal Purple in other cars I've owned, and it works just as well as any others. But...since it's not on the MB approved list, I won't use it in the Crossfire. And to my knowledge, there is no such thing as SAE1, only SAE (Society of Automotive Engineers). The 1 must be a typo. As far as the difference in price, I have not a clue.
