Hey guys done some research on this protek-r rotary motor oil any users? And how good does it seem to work for you guy? Is it worth it?

Pettit Racing recommended.. I think is more than a simple "auto lub" or "2 stroke oil"

Protect and give a little bit of compression in some cases

Awesome are you a user yourself?

Yes I use protek as well. I believe in Pettit and there knowledge. And i have actually seen other people using serious amounts of different oil like a 2-stroke

Yea I was thinking of using 2 stroke oil or just putting conventional oil I just want the best thing to keep motor clean and I saw the protek and was curious to see if it is actually worth it

I have not used it, but have some experience with oil development for rotary engines, so I went to pettit's website to read about it.

All I can say is whether or not the lubricant offers any performance, that marketing website is a huge load of bullshit.

Just to point out a few things:
1) most rotary engine failures are not due to frictional wear anyway, but their claim that wearing out engines is "good for Mazda" is ludicrous, Mazda has been fighting the image of the rotary as unreliable since the 60s.
2) all of the claimed benefits of protek-r are no different than any brand of premix. They give no data as to why this is better than 2 cycle oil.
3) "blends completely with the fuel and will not separate" is about the dumbest statement ever. The whole purpose of 2-cycle oil is to separate from the fuel as a lubricant film on engine parts. If it will not separate, ever, than how does it lubricate surfaces that are not coated with fuel spray?
4)The comparison they give is really, really bad. There is no data about the conditions these two housings experienced or how to assure they are comparable. I do engine testing for a living, and the single most important rule is to consider all variables. To set up a REAL test for effectiveness of this oil, you would need to run two housings, in the SAME engine, through a series of tests, one with and one without the oil. Realistically, you would also need to either run two engines, or at some point swap the housings front to rear, to try to single out the oil as the driving variable behind wear differences.
5) Just to add to this point, I can go to my shed right now, and find you a 60k mile housing that looks like crap, and a 80k mile housing that looks great. Any shop could find you 10 of each. Without a specifically designed comparison, the only reason to even show this is to fool people into buying something because you have no REAL data that shows that it works.
6) Speaking of data, where do I find ANY data as to the physical properties of this stuff other than 'we tried it and it is magical unicorn **** snake oil that made our cars awesome'? Typically when considering lubricants, one would examine lubricity, viscosity, flash point, etc. In this case, the basic data is maybe less applicable, but there are various standard wear tests that could be performed in a controlled environment to prove any usefulness, and I see no such data.

Put whatever in your car that makes you happy, but as for me, I get a bit irritated when companies promote some product based on a lot of misleading information, and doesn't provide any actual, useful performance data. I'll stick with a quality 2-cycle oil.

Regardless of the above tirade, just to address this question, DO NOT use motor oil as a premix. It does not mix properly with the fuel, will not effectively lubricate the engine, and will leave deposits as it will not combust completely.

2-cycle oil is quite different from motor oil and is specifically designed for this application (or at least the piston engine equivalent) to avoid the above listed problems. Any kind of 2-cycle oil is far superior to motor oil for premixing purposes.

Oh thanks patman I ask because I saw a video of it compared to a 2 stroke oil and a mineral oil and the petit motor oil seemed to burn off cleaner with less carbon build up and from what I understand carbon build up is what makes the rotary fail as you loose compression or the rotors gum up and get stuck. So you use 2 stroke and mix would you recommend mixing? And what measurement do you use for the mix if you don't mind me asking?

Thanks Patman everything that you say makes sense after doing some research it seems to be exactly what you're saying very heavy marketing and I've been using the stuff for about four years now. I have a neighbor bought my FC and he's actually putting two-stroke oil in it and it runs like a banshee quad ix the only way we compare it dark smoke coming out
This was a good thread thank you
