Polymer Dynamics makes low-friction engine coating. This product is proven in racing.

so where would that be on the Renesis hmm?

 

just an oil additive, like Slick 50... i'm skeptical of stuff that makes such claims, and is "race proven" (often not run in the cars, 'cause often race oil is tailor made to the engine, or at least application...)
just baloney... with a website that crappy, i dont' think they've secretly stumbled upon some chemical second-coming, without Exxon, Shell, or some other oil-super-giant buying them up with pocket change and developping it further.

 

you can consider Militec-1 tho

not sure about rotory application

heh heh, that seems like pretty cool beans... maybe useful on the rotor itself... but you've gotta remember that on the housings, stuff is sliding around on there, and it moving the right way is more important than slightly (or even greatly) improved thermal efficiency...
but i could certainly see something like that working well to insulate the rotor itself against the engine heat, improving thermal efficiency a little bit, and protecting the oil a little more too, eh??

 

I'm guilty of it too, I'll admit it.. I don't judge people by the content of their character, but by the appearance of their website

 

Ouch! That site i really bad!

 

In my admittedly uninformed opinion, I would be very wary of oil additives with the rotary engine. With the rotary using (burning?) oil naturally, I would expect an additive to sludge up the rotor housing and gum up the apex seals. I will just stick with organic oil and change often.

 

It is possible to coat the inner surface of the rotor housing.

Ceramic coating is ideal for aluminum alloys.

 

well, the problem with sales brochures is that they're made to sell things, and might tell you little white lies with very little quantifiable information...

also, we aren't Mazda RENESIS engineers, and known't the properties sought in creating the "perfect" rotor housings and thus can't really conclude whether or not your comprimizes (including the cost one) are better or worse with the ceramic coating on the inside of the housings...
but, like i said before, i don't see how it would do any harm on the rotor itself, other than if it might be adversely affected by the conditions of the engine?? again, we don't know all teh specificities needed to draw a certain conclusion.
