Seems to be the same, but meh I would use something else. It's pretty pricey, and according to racing beat it's only a tcw 3.

I'm sure you could find something better locally, I get my Kawasaki fd rated gallon for $30 locally.

I don't use Royal Purple anything. Overpriced and overhyped mediocre products.

This makes me dissapointed, The owner is a rotory guy but his products just dont hold up as well as other choices that cost a whole lot less money.

Besides, there's no evidence that premixing does anything for the RX-8 anyway.

There's no evidence that it doesn't do something either

Exactly. But is sure helps most of us feel better

pistonhater

Wrong.

What about the pile of premixed engines that have failed? Some even failed with the Sohn adapter, lol.

that just proves the engine failed, not that the engine failed in a manner which one would have expected otherwise due to premixing.

"It's strange, I never would have expected that guy's premixed engine to fail. Never mind that he ran it out of coolant, the premix should have saved it anyway!"



(sarcasm to illustrate a point)

pistonhater

Premixing is like the belief in god and prayers...it makes people feel good even if they can't find evidence that it works, LOL

pistonhater

I hope you are aware of the fact that many people including some vendors and manufacturers claim that premixing extends engine life.

So if you premix believing it will make your engine last longer but it doesn't , what else would you conclude when your engine dies young?

That you...
...had a cooling system failure
...ran it out of oil
...the company lines clogged
...used wrong octane
...choked it to death with carbon
...had a poorly built engine
...had a severe cat clog
...had a lean spike from a failed fuel pump
...tuned it bad
....drove it through deep water with a low mounted intake inlet
...etc

If you run premix and expect it to be the end all of all your problems then wow... You have to be damn stupid.

Premixed engines that were torn down were generally much cleaner upon inspection than those that didn't run any premix. Take it as you will.

Series 2 renesis has an added oil injector in the center of the housing (along with other improvements) it's safe to say that those changes helped improve engine life. Premix fills the void that the series 1 is missing with only 2 oil injectors.

The center of housings of premixed engines have less wear.

If you think premix does nothing, then how could previous rotary engines get away with running nothing but premix on disabled OMP?

Yes it's a different engine, nonetheless the concept of premix and it's function is the same.

Premix works.
Cause I said so!


Nana nana na na.

I have been using Pettit Racing Protek-R in several of my rotary cars over the years with great results. Pettit has used this in their racing rotaries for years, as well as loads of street rotaries. I have used Amsoil products in the past and also Pettit products in my race-prepped and street rotaries and have never suffered a rotary engine failure ever, and that rules out any engine failures due to poor internal lubrication.

Everyone here is free to have their own favorite pre-mix choice. The fact is Pettit has sold a ton of Protek-R to many satisfied rotary owners,both racers and street drivers. I am satisfied that it works for my cars and will continue to use it. And I have had no problems with ordering it and delivery.

This debate will never end will it? lol, I have the ever non popular 2004 series one automatic( carbon catcher). I have some where over 84,000 miles now. I have tried several synthetics including royal purple. I am currently using amsoil in the crank case and a 2 cycle in the tank, 1/2 ounce per gallon. I am very satisfied at the performance and idle as well as miles per gallon increase i have experienced. Some folk need to quit trying to sell their point of view and just research and make your own choice and just do it. Synthetic and pre mix is the way to go for me.

pistonhater

I don't follow your logic.


So you don't believe there's anything wrong with the false claims about premixing?

What about the pile of non premixed engines that have failed? Some even failed without the SOHN adapter, lol.

This thread has run it's race..

There is more than enough information within the 150+ pages for anyone to decide on what owners want to do in regard to Pre-Mixing in Rotaries-Renesis.

The debate is now quite frankly boring and at times juvenile content.

Just to close the case of pre-mix, the only reason one pre-mixes is to add to and assist in additional lubrication of internal engine parts namely, Apex Seals and Side Seals and the surfaces which they run on.

If any owner starts to pre-mix (first time), on an old engine which has already done XX,XXX amount of miles then there is already 'wear' on these components, pre-mixing is not going to realistically assist these already worn parts.

The reality is Mazda failed to correctly identify the issue of oil management and wear in the center area of Apex Seals (hence the additional 2 injectors on 2009-2012 RX-8's) where Mazda has always had oil directly injected/applied in this area on all previous RE's from 1985-2003.

The only simple way to adequately issue oil into this 'center area' of Apex Seal is through pre-mixing in 2004-2008MY RX-8's.

Or if you choose to use pre-mix in 2009-2012 RX-8 it will not harm engine or work against it's existing first ever electronic metering oil pump system.

I am closing this thread for the foreseeable future.
