I would recommend to stay with the OMP. I pre-mixed for a while, and it works fine, but the motor will stay oiled better with the OMP. I had 2 lines cut off going to the intake manifold, and I still premixed since none was getting to the rotors. The OMP did the work of oiling the eccentric shaft areas, and the pre-mixed fuel oiled the rotors. Worked very well, but I do recommend the OMP. Also, the lines im not sure about. The lines are pre-shaped to contour to the motor to reach the destinations they are required to. Im sure you can upgrade them though to something else.

It doesn't work that way. The oil pump proper, located behind the front housing, circulates the engine oil. The OMP receives oil from this pump, but contributes nothing to oil circulation beyond sending tiny amounts to the nozzles on the housings.

If the OMP was responsible for lubricating the e-shaft (and everything else) then the engine would turn into a big, unhappy metal grinder shortly after we pre-mixers removed the OMP and blocked off its opening...

well regardless i still don't feel like premixing. I prefer just changing my oil every time it is due. Not adding premix everytime I need to pump gas.

Listen AMur- there is no need to dissect each comment and pick it apart. I am well aware of the different methods that you can put oil into your fuel tank including long neck bottles. I have one in my car. I have also seen people at RX7 cruises whip out their funnels and pour oil into their tanks, I was only giving all scenarios. Im glad you are so wise and all the other drivers are so dumb. Your thoughts are its easier to pour 2 stroke into long neck bottles at home and carry them in your car or hope you can find these at the gas station when you forget- your right, that is much simpler then just putting fuel in your tank.

Its like your saying the OMP is a time bomb, im saying most engine failures have nothing to do with the OMP so what is so hard to understand about that? What about the cars with hundreds of thousands of miles doing just fine on their OMP system?

And again im glad you are so scientific about your mixing ratios and again im going to say when I have been at RX7 meets and cruises and see puffing 2 stroke coming from the tailpipes and soot on the bumpers I guess they are all mixing incorrectly too, and again im giving general statements based on what I have seen.

I put ALOT of time into my car so dont "roll your eyes" at me saying I cant wait for some oil to make its way down into the tank, that is not the case, you dont even know if I premix or not, you just make your statements like its the final word on the subject.

You want to help the uniformed tell them all the situations involved.

And you can never, ever try to convince me that a car running 2 stroke will produce cleaner tailpipe emissions then a car with its OMP system


These are opinions on this subject so relax yourself buddy.

From now on, when you have no idea what you're talking about, just avoid posting. The OMP has nothing to do with the eccentric shaft.

No one said that the OMP couldn't keep a car running for hundreds of thousands of miles. It's just rare. Most rotary engine failures are carbon related and some of us relate that right back to the OMP. If you choose not to, then more power to you. It's your car.

If you can see "puffing 2 stroke" the mixing ratio is wrong. Have you never seen soot on the bumpers of other cars?

Again, you miss the point. Some people care about looking pretty and others care about the condition of their engine internals. I for one could care less about tailpipe emissions. What I am concerned with is the general idea of injecting oil, that is not meant to be burned, into the combustion chamber. Does that sound like it makes sense to you?

i give up on this, I dont know why some of you are so opinionated on a simple question, if you want to premix go ahead and do it, the subject has been covered thousands of times so there is plenty of information out there.

for the record- I inject 2 stroke through the OMP, but sometimes I will put some in the fuel tank.
Before when the car was NA its 155k mile motor was in perfect shape, and still runs today in another car I put the motor in. Out of all the FCs I have owned, and I have owned my share, none of them had a engine failure from carbon, the 2 I bought with bad engines had overheated.

Yes, there is a need. Do you even know what the word debate means?


No, you gave only one scenario, implied it was the only scenario and tried to use it to degrade a perfectly valid engine-care strategy. This was either ignorant or dishonest of you.

Dishonest, then. Ok, gotcha.


I haven't said any of these things. I have described how I premix and what the experience is like. I haven't said a word, insulting or otherwise, about people who don't premix. You're pulling this bs out of thin air.


For the second time, no one has said that. You're making **** up. Aren't you embarrassed by that?


I have no idea what was happening with these many alleged cars that apparently only you can find. Again (can't you read?) you'd have to use a ridiculous amount of premix to get smoke at the tailpipe. Either there was some other issue with these phantom cars or, far more likely imho, the owner didn't have a clue what they were doing and dumped in far too much premix. In either case, the owner isn't caring properly for their car which means your argument is that nobody should premix because stupid people will do it incorrectly.


I'll roll my eyes at anyone who posts misleading, exaggerated and dishonest information.


I didn't say it, I suggested it and waited for you to refute it. There's your reading comprehension issue cropping up again...


What does this have to do with anything?


Funny how you neglected to do this but require it of everyone else. There's a word for that, isn't there?


This about says it all. Lightweight oil that was designed to lubricate and burn off versus a heavier oil that was designed to lubricate and never intended to enter a working combustion chamber.

Discussing car care with people of your caliber is a waste of time.

Out of curiosity, how are you going about this?

Gabriel82

iTrader: (8)

I am just amazed how my question was answered and people are still disputing about the methods are being neutral among the methods. Like aaron said if you don't want to use pre-mix then don't and that's what I am going to do. If my OMP goes bad well just get another one. I personally don't want to be putting in pre-mix every time I am at the pump, which is frequently because I drive an RX7 hahaha

gabriel- when your OMP goes bad it can usually be rebuilt with a kit, Pineapple Racing sells this kit.

Rob XX 7: sweet now I know where to look when it goes bad (hope it doesn't happen any time soon after my engine gets rebuilt) but yeah I have bought stuff from Pineapple and talked to a dude from there good people and have good products

premixing is no fun.. no fun at all! lmao . brings your overall fuel cost up a lil bit lol. Giving people rides than they give you a few bucks for your gas .. "Hey what about a few bucks for my 2 stroke oil!?! you used that up btch!" hahaha jk

If your S5, you will need to get the ecu chipped since it has instructions to function with teh OMP, and will go into limp mode with it removed. I actually damaged my omp when i fitted a S4 water pump assembly, so i went block off and rtek 1.5 ecu chip. I daily drive my car everyday and keep a quart of 2stroke oil with me.

If you dont have to drive everyday or have 2nd transportation, its no problem, but if you drive everyday where fill ups are constant, it can be annoying having to pick up more oil when you need some.

If your OMP works, don't touch it (or add one of those nifty 2 stroke adapters that pulls oil from an external tank). Replace your lines and test the injectors to make sure they're working right and you're golden. The OMP in my first FC failed, so I'm stuck premixing (plus I felt all cool back them having to explain it to people ). Now I'm at the point where I don't care enough about the car to gfo back and re-install the OMP, injectors, lines, etc.

My 'build' for the other FC will include a rebuilt OMP and a 2-stroke adapter with external oil tank.
