Its on their website. This goes back to the fact that when mobil1 first came out it destroyed seals. Both the seals and the oil have been reformulated multiple times since then. I use Mobil 10W30 and have for +30K miles with no problems.

There's been tons of rotary rebuilds that prove 5W-20 is too thin protection wise. Plus Royal Purple has a FAQ on their website stating they have done extensive testing proving their synthetic is fine to use in a rotary. Synthetics are fine..

not because of different material... but because of tighter clearances kid... btw miss u guys... have a different number now so if you want it pm me....

I'm using Mobil 1 5w30 also right now also, don't think I'll be going back to MRO any time soon

I hope it aint eating up my seals. I done about 2,000KM with Mobil1 now.

The O-ring is a different material though right? Prior renesis o-rings would shrink with Synthetic?

This is my understanding anyways.
