Royal Purple ?
I know there has been many discussions on oil here, with many different opinions. I was thinking about using Royal Purple on my next oil change and wondered if anyone here has used it successfully. I checked their site (I know its their site and they are trying to sell a product) and it states its approved for Rotary engines. Any comments/suggestions???
Thanks

I use it religiously... Oil, gear lube, trans lube, etc.. I do get it at a 25% discount, so it does help the price.
Seems to be good stuff. I am going to swap to dino oil in my 1980 because the oil seals are shot and she uses too much oil,,,,,

I would prefer Mobile 1. I have seen royal purple come out of a few cars and there was medal shavings and in one car a certain build up that had little chunks. I have used Mobile 1 forever and seen boosted cars make it past the 250,000 mile mark. Never experienced royal purple with a rotary though only DSM's and such.

I have used RP in rotaries. Great stuff. I got 28mpg highway on my drive up to school with RP in the sump at 78mph. I averaged 23mpg on the highway with conventional 20w50. Same drive. Similar weather (temp., humidity), same speed (78mph). It's good stuff.

I also use RP. Interesting story as well:
Last year I went to ZOOM FEST. For those of you who do not know what that is (Shame on you!) it is a Mazda meet in the middle of summer at Road Atlanta, http://www.youtube.com/watch?v=kARKG...eature=related . Anyways, last year it had to be 120* on the track, easy. No wind, just dead heat. I had RP in the whole car and when doing the "Parade laps" (which ended up being VERY spirited driving on the track), my oil temp was hanging around 175*. This was without an undertray.
Flash forward to this year. I was getting ready to go down to ZOOM FEST again. Money was short and I sprung for some Mobil 1 oil in the engine. It was a lot cooler this year, with some wind involved. The parade laps were slower and I never really got over 70ish. Oil temps? 180*.
That was enough to make me switch back. I wasn't pushing the car near as hard as last year and the RP seemed to cool off faster than the Mobil 1 did. Not bashing Mobil 1 or anything, but my baby got RP when she came back home
