Use the search...it's been discussed for years.
If you have an S5 it's controlled by the ECU and S4, well, a rod. It depends how much you mash the gas. More you push on the pedal, the more oil it injects.
It's not something everybody is willing to do. When you totally disable the OMP, you need to always use 2 stroke oil (TCW3). Usually 1/2 oz per gallon. For me, I don't care as long as it's better for the engine. A 30 sec. extra to fill in gas is nothing but for some 30sec is a big deal.

i premix with the omp intact, I just use less. I've read the omp doesn't fully lubricate the entire area inside the housing, just closest to the oil injector-at least not a 14 year old oil injector.

The purpose for running pre mix is to reduce carbon deposit in the combustion as well as better lubrication.
When the motor was taken apart a few years ago, there was too much carbon on the rotors. Premix is designed to burn, not mineral oil. Recently I tore down the motor using pure premix and there was almost no carbon anywhere. The rotors were clean, the side springs were free from any carbon, the apex seals were clean and shiny and the grooves had no carbon deposit. Compared to the motor using mineral oil, it was night and day difference.
This debate has gone on for years. It's up to the owner what he/she wants to do. I'm happy with the premix.
The premix proved it reduced carbon. That's enough proof for me. If I were to buy another RX7, I'm doing the same .
