Royal Purple 5/30 and 10/30 - 986 Forum - The Community for Porsche Boxster & Cayman Owners

I went to Advanced Auto today to get some Royal Purple. They only have 5/30 and 10/30 in stock. Is there a problem or risk with putting either of these weights in the car?

Pretty sure Royal Purple makes a 5W40. If you want to go with RP, I would use the correct weight.

The vario-cam mechanism is sensitive to oil weights.

Thanks to both of you. I called Advanced and spoke with an informed person that said I absolutely need the 0 weight and recommended I go with 0/40 [RP doesn't have a 0/50] even though they don't carry it and can't order it. I found a 'performance' shop that will match the [coincidental] Advanced Auto sale price. Today is a great day.

thanks for your research.

5W30 and 10W30 are for Japanese motors. Could do with 0W50 or 5W40 I guess depending on the climate of the state you live in.

Until Royal Purple (any weight) has ACEA A3, B3, B4; I wouldn't touch it............

IMO if it's not on Porsche's list of approved oils don't use it.
