Somebody Help, I am a dumb ass.

actually I haven't but for anybody who doesnt know, let me go over some of the benefits. First of all, 4 stroke oil is not designed to be burned!! It creates carbon desposits when it burns which can build up. 2 stroke oil on the other hand is designed to lubricate and burn CLEANLY.
Also on a well used rotor housing, you can see below the oil injector a small dribble where the housing is less worn than everything else, due to uneven lubrication. Premixing allows for better overall lubrication of the apex seals, and burns much cleaner inside the engine. Premixing MMO (marvel mystery oil) will prevent carbon deposits as well as eat up the carbon that is allready there.
Premixing is better for the motor, but its not a great selling point to have to premix your fuel on a production car, so we are stuck with the lazy man solution of the metering oil pump.
Premix if you can folks, it really helps. Just make sure its MMO or a qualilty TCW3 rated 2 stroke. Im currently using royal purple synthetic 2 stroke in my motor. So far ive had great results.

Mazda chose to go that route just like Matt said above, as a selling point. People don't expect to have to pre-mix their fuel in their vehicles because 1) its an extra step. and 2) there is some math involved. Mazda's best route perhaps could have been having a 2 stroke resevoir that would just get topped off like wiper fluid or coolant but for some reason didn't go that route. I am not completely sure of the reasons but I think it was something similar to why 2 stroke vehicles are "off road" vehicle (emissions requirements).
I know personally I would find it odd to purchase a new car and then be told that a warranty requirement was to pre-mix at each fill-up. I think Mazdas did it for warranty purposes also. Yes OMP does "work" but only as well as the person who own the vehicle keeps the oil changed and full.

so, why would they do that as a selling point if it's not the best for the engine? by the sounds of it there would be alot more warranty uses than there is. so why would engineers produce something that will fail? and if it has to do with emisions, well then why is the argument that 2 stroke oil burns better? if that is so and they are worried aout emisions they would have done that way. hell, back in the early 70's with the r100, rx2' and 3's there wasn't any real emisions around. you would think they would have done it back then if that was the reasons. yet they didn't. so maybe oil burns etter than you all think? or it could be that since the oil doesn't burn as good it leaves a film that protects the housings better than 2 stroke can ever do? i still believe the mazda engineers have insight that mos of us do not.

so wut wold happen if i premixed with the omp still hooked up and working. would i get superior lubrication or would it just be a bad idea?
thats what i do acually. yet sometimes i forget to premix. but who cares i still have the omp working well.

oh yeah theres no harmful side effects to the filter or seals? im just wondering i dont really care about emissions also why dont i hear more about other people doing such a thing if its better for the engine? i mean you really cant go wrong with 2 sources of lubrication.

people are lazy. Thats why not everybody does it. Premix is done CONSITANTLY in many many rotary race cars.

The OMP system is set up for normal use of the engine. Many folks push the engine beyound normal use with high revs and lots of heat. The OMP just can't keep up with this. Pre-mix allows you to adjust the mix to your driving. Running both a light pre-mix and the OMP can be the best of both words. Lots of lub when you need it on high revs and morderate oil other times.
I am with Hornbm, if you are going to burn oil, why not use oil that is meant to be burned?
