2-stroke oil in the tank: Do you use it?
Im just asking everyone on the forum what the Pro's and con's of using 2-stroke motor oil in the tank. Also if you follow the recommended amount of gas/oil mix or have your own formula that works well. thanks ahead of time.

ok i cause i see many people who post about using it but no one mentions removal of the OMP. so you only use if the OMP is gone? or are there other factors?

As mentioned above in my post. Only run it if you're Omp system is not working or you have it blocked off. The reason people premix that have omp's is because they aren't sure if it is working or not. If your not sure, then use premix in your gas tank and then start your motor and pull your omp lines off and see if your omp is working. If it is then I wouldn't bother with premix unless your building a full race motor.

I wouldn't bother with it. What's the motive -better lubrication? How much better is it? How much is it going to extend the life of the rotor housings, if at all? Chances are something else will destroy the engine before that even becomes a factor.
The exhaust will smell more, the interior will smell like oil if you store it in there-no matter how many protective measures you take, and you will smell like oil every time you fill up the car. IMO it's not worth the hassle if you can avoid it.

I run it. Have been for 8 years now sans oil metering pump. Seems to work very well! I've been using it long enough to see that the irons and seals seem to be in very good shape upon tear-down.

I disagree on all points above short of a bit more of a hassle adding oil at each fueling interval.. Better lubrication due to injector pattern and under high pressure which will give more complete lubrication coverage. Exhaust smell is far superior due to the oil being actually designed to lubricate/ burn in a motor. Go with castor oil if you like the smell of snow mobiles or 2 stroke motorcycles.
For a race car I can see the rational, but for a street car it seems like far too much trouble. Also keep in mind that unless you eliminate the MOP altogether, the exhaust will smell more and emissions will be worse. If you do eliminate the pump, then you will probably have worse lubrication at cruising speed when the AFRS are lean due to the reduced volume of fuel (and consequently oil) going into the motor.

It doesn't sound like you disagree at all then. I never said it doesn't provide better lubrication, just that it probably results in little benefit given the hassles and the other more probably causes of engine failure.

Also, lubrication at cruising speed is superior. The stock MOP burns approx 1 quart of oil per 1000 miles city/highway @15 miles per gal. or 66.6 gals of fuel per quart of oil. If you run the rule of thumb (deleted mop) 1oz per gal. you will burn through 66 oz of premix or slightly over 2 quarts.
