Been using RP in my truck and coming up to an oil change soon. I bought Royal Purple HPS thinking it was an upgrade over "standard" grade. Was reading the label and it says it is not API licensed and there is no API cert either. Anybody know if this is a good oil for us to use in the 5.7's? I originally went with RP because it met FCA's certification.......
