now you bastards have made me want/need to go out and buy some 2cycle synthetic to premix with.
One question -- since its obviously oil i thought oil never mixed with anything? i guess the gasoline breaks it down so it properly dilutes throughout the entire tank?

a more technical person with have to answer that one... i just know that the syn burns cleaner... you will see a big diff in the smoot factor...
more so if you are using syn motor oil in the car... my smoot takes about 1000 miles to build up enought to even clean... and it comes of very easy...

the best way to do it would be to put the oil in a gas can add a gallon of gas and shake it up. then put it in the car and fill it up...
but i just put it in before the fill up and let the filling mix it up... have had no problems...
the method i use is... i went out and bought 120 5oz dixie cups. it cost about 2bucks... i keep them in the trunk..
i put the oil.. into the cup and dump it into the tank. then fill. i am down to about 3oz now...
also note... i am premixing to fix / cover up a problem...

a decent quart of premix cost no more than 5 bucks. and you just need about 4-6oz of it for every fill-up, thats with a functional OMP/MOP of course.
a Quart should be able to last you 8 times (say if you put 4 oz each time)
So its not so bad I guess. plus the protection it gives ya.
Alot of rotary owners , I mean people with experience like most 7 owners, just removed the omp/mop all together and use premix only, with a lower ratio of course, say about 1:100

I thought castor was a good thing? I know in RC 2 stroke engines, the castor leaves a waxy like varnish coating that reduces friction and addes a protective barrier if there was a potential for oil starvation.

they use conversion by using the fact that 1 gallon = 128 fluid ounces... so if you use 5 ounces of premix for a 14 gallon fill up, then that is about 358:1 ratio

Ive followed so far but one thing I do not understand is the "functioning OMP/MOP"
I havnet modified my engine in any way so far (especially the oil system) so would dumping 4oz of premix into the gas tank work for me? or is there something else I'm missing?

Here's yet another data point.
I use Echo Chainsaw oil (two stroke) available at your local Home Depot. It meets JASO standards which are considerably higher than TSW3 (meaning that it creates less smoke or ash deposits than TSW3 2 stroke oils). I've tried Marvel Mystery oil in the past as well and personally I didn't like the Marvel Mystery oil since it left tons of soot deposits on my rear bumper.
The biggest difference I noticed was smoother starting and better engine vaccuum on my engine boost gage. For street driving I use 4 oz per tank (8 oz if heading for the track). The Echo product is totally smokeless and leaves no soot whatsoever on my rear bumper.
I have heard in the past that premixing will shorten the life of your catalytic converter which may be something for 8 owners to consider. Granted OBDII cars have a 5 year exemption (at least here in AZ) from their first emissions test, but 5 years of premixing "may" take a toll on your cat. Just something to think about. In my case, I feel that the benefits far outweigh the risks.

I use Marvel Mystery Oil in my RX-7. Its also handy because there are marks down the sides that show the oz's in 4-oz intervals. OMP disabled, so I mix 1oz per gallon of gasoline.

I've been using Yamalube 2-R for a couple months now. Haven't had the recall performed yet, so this seems like good protection until then.

It 's best to use Yamalube S
S is made for injectors, it's much thinner.
This will not clog the orifaces that drop oil on the Apex seals.

Incorrect oil does cause carbon build up. We think that's why Mazda doesn't like Mobile 1. But we are not sure. Mazda does not recomend Synthetic oil that they haven't tested for this reason.
Not only can the oil build up on the plugs, but also along the APEX seal.
This is why one needs to be careful when chooing a pre-mix.
And becareful on the amount mixed.

No the 2-R is the correct stuff because the S is dirty crap oil
