I know you guys have herd of that royal purple

motor oil. Has anyone tried it on a rotory? https://www.nopistons.com/forums/pub...DIR#>/wink.png

I used it in my TII for 1/2 of an Autocross season. My car ran noticably cooler. I love it. I am going to put it back into my FD engine this week before my 1st AutoX.

I run synthetic 10w-30 in my "crankcase" and the synthetic 2 cycle premix in the tank. Won't know how its works till my car is running though https://www.nopistons.com/forums/pub...DIR#>/wink.png

RP is good stuff, as long as you are running Premix

so its not something I just put 5 quarts in and do an

oil change with i guess.

Unless you have a budget for that https://www.nopistons.com/forums/pub...IR#>/smile.png

RP is great from what I heard.

I am running Royal Purple, last oil change was the first I have used it so I dont have alot to say other than RP hasnt somehow made my car blow up unexpectedly.

at sevenstock5... Royal purple had a stand there... they were saying you can use it... but mazda doens't endorse it...(liability reasons)

its just another brand of synthetic oil thats all.

I think people just hop on the RP bandwagon when any synthetic will do

the same job, AMSOIL is a superior synthetic.
