    Anyone using Royal Purple HPS 5w30 oil?

    Anyone using RP HPS 5w30 oil? It is suppose to be better than the regular RP 5w30... (more additives). All RP oil should meet BMW standard right? I'm about to pull the trigger on these oil but I just wanna make sure. RP HPS or regular RP? Click here to enlarge

    Never tried it but I don't see why the HPS would be worse? What additives does it have?
