How many of you use pre mix in your gas and have removed OMP. Also, how much do mix in a tank of MMO or 2 stroke oil? And what are your thoughts on pre-mix?

SoRRoW

OK I couldnt vote..I ran premix and the OMP..

need to find a dam block off plate

I have the OMP and I premix. I used to premix 16oz per fillup but now I do approx. 10oz per fillup.

Carbon seals triple there life span if you use 2cycle oil and do all the other things your supposed to do. I use 1oz oil/gallon gas on my bridgeport, no omp. I believe they can last longer then 20,000 miles since I have more then that on them already! I had to take it apart for a stationary gear failure and they were with-in a millimeter of their orginal height thickness. I guess as long as you drive it hard and not drive it light for long duration(causes carbon build up on the tips of the rotors and causes the apex seals to stick). This is why you are required to always drive a carbon sealed rotary hard since they don't seal well at low rpm causing carbon build up and blowby. Its a little off the subject I guess.

BUT, stock seals will benifit also greatly from 2cycle oil mixed in luburcating the apex seals and housing better the regular engine oil since its designed to burn and is uniformly mixed with the gas and lubes all the surfaces, and ofcourse the apex seals' groove in the rotor, causing less ware.

I personally like the idea of suppling the OMP with 2 stroke oil. There is an adapter somewhere that allows you to do that I just dont remember where.

I still run my OMP but I also pre-mix 8oz MMO per tank full.

Pre-Mix only here.

I have a 91 tII motor in going in my car.

it uses electric injectors for oil metering, and the haltech wont run them.

Plus, I think 2cycle seams much better for the engine.

mwpayne

Now THATS a cool idea, loading the OMP with 2 cycle. i'd love to know how to make that happen!!
C'mon, you 7 guru's!

Rex4Life

Just started tonight with 6 oz in a tank + OMP in my SE.

After my TII conversion I plan on running straight premix, removing OMP, and fitting a OMP block off plate with a turbo drain.

too lazy to premix, OMP all the way.

hornbm

from what I remember, it was a spacer that went in between the OMP and the front cover. It had a had a hose that you would connect to a seprate tank that was filled with 2 stroke oil. Therefore supplying the OMP with 2stroke oil.

However I've heard that the OMP doesnt do a avery good job at dilevering oil anyway.

Suparslinc

I used to run castrol 2 stroke oil; now I run about 4 ounces of MMO.

I still have the OMP but I don't trust that thing.

FB II

are you guys pre-mixing cause somethings wrong with your car? or what. i have never done this.

SoRRoW

Pre mixing assures you that you ARE getting oil to the rotors through your fuel ,

I can personally say MMO has kept the carbon build up down in my engine and seals clean and workin order..

I have tore down a good amount of rotary engines,enough to compare on..

Most normal maintence engines I have seen stillget a little carbon on the inside..

Well I took my 84 12a apart about a month now?
I couldnt belive how clean the engine was inside..

Yes the rotor sides did have carbon still..but that was nothing...The seals were so clean,shiny,and oily the did not stick when pusingh on them /side seals,apex seals,corner seals..

I want to run a block off plate..
I dont think no one makes them ,so im gonna see what to do on making them my self..I just been sick as a dog,staying home for last couple days dont feel like doing **** but get on here to bullshit or lay down..

Alright, I know 2-stroke oil is good for my car, but what brand are you guys using? I know nothing about 2-stroke oil, so fill me in on which I should buy. Oh, and once my OMP reseal kit come I'll be using that adaptor. Too lazy to premix too.

Conway

AdamAnt

That pump adapter is sweet. I'm gona do it. Will post pictures when it's done. I will need an oil resovoir. I remember the Toyota Previa had an oil resevior for engine oil, might be usefull in this application to hold the two stroke oil.

First I'm going to take off my rats nest and clean up the engine bay.

Maybe sunthetic motorcycle two stroke would protect the motor well?

BRealistic

WHy not run the adapter, and run the oil lines into some type of fuel chamber near the carb- for the fuel to mix with the 2 stroke oil instead of just dripping the oil in the intake?

AdamAnt

Good idea, but then the fuel going back in the tank would be premixed and then mixed again back in the carb, casuing an increased ratio as fuel returns through the system

BRealistic

Well, I am talking about the carbed 12a in my car. I assume at some point the fuel isn't returning.

AdamAnt

Maybe at full throtle going up a hill. Otherwise it is dumping back into the tank through the return line.

I've been running the adapter for like 6 months on my 89. (When the engine finally goes on my SE, I'll probably run one on it, too)
I use the adapter as well as Premixing around 1/3qt of 2 cycle per fillup. Sort of a best of both worlds thing.

For the oil storage tank I used this:

http://www.behrents.com/Merchant2/4....-jr-drag-cells

The Cap is wide mouthed for easy pouring, it has a one way valve to let air in as the oil is used while keeping the oil from spilling out on corners, and it also has an outlet valve to shut the flow if you should have to remove the reservoir for something.

It actually holds about 1 1/4 qts and the outlet is the same size as the one on the adapter.

Well worth the 30 bucks, but a simple lawnmower tank will work as well...

If you do go premix, make sure you use an oil with at least a TC-W3 rating. It stays in suspension longer, ashes less, and lubes better than straight lawnmower oil.

I would NOT use MMO to premix unless I was running it in addition to the OMP

AdamAnt

Actually I think I'm going to buy the adapter for the OMP and set up a resevoir with synthetic 2 stroke oil. I don't think premix is a good idea for me, since my car sits in the garage from Monday to Friday and only gets driven on nice summer weekends and I don't want the fuel and oil seperating in the tank. Anyway I like the idea of running the omp with 2 stroke oil. And as far as MMO, you can't even get it in Canada anyway.
