So is Royal Purple a good idea for a Renesis engine, from a 8 ofc.

I'm not being anymore specific because anyone who knows the answer should understand my question

please help me I'm confused now

5w-20
from what ive read it specifies in the owners manual says it needs to be API Service SL and ILSAC GF-3.

royal purple says Exceeds API SN. ILSAC GF-5 specifications
castrol syntec says Exceeds API Service SM, SL, SJ and SH; API Certified Gasoline Engine Oil; ILSAC GF-4/GF-3/GF-2; Ford WSS-M2C930-A and WSS-M2C153-H

just look for the appropriate ratings on the oil and pick whichever brand you want. i would suggest waiting around for some more answers by other people that might have more knowledge on the renesis as i just searched around on some mazda and rotary sites for the info i found regarding this.

dem apex seals brahhh

And cooling issues duhhhh

since it burns oil anyways you just gonna be spending mroe on that royal purp then any other stuff you put into it

This lol

Does anyone have an answer?



Thanks for the effort

I know a guy that used to be a formulation chemist at Sunoco and he said he wouldn't use Royal Purple to lubricate a sandwich.


There are better oils for the same or less money. Now, as to what works well in the Renesis I can't say. I've never spent any time around them.

this, royal purple is junk

Redline, Brad Penn, Joe Gibbs, even Valvoline VR1 if we are talking race stuff.

Pennzoil platinum and Castrol Syntec for pretty much everything else.
