OMP with Premix ?
I have the OMP still intact and i am also premixing (200:1), what i did though was disconnected the OMP lever, so that the oil volume will not increase with the increased RPM's. The reason i did this is because the fuel injectors are cut off when the RPM's decrease, as a result there is min. lubercation for the Apex seals. So i left the OMP in place at its lowest setting to keep the engine lubed up when this happens. My question is does this hurt the OMP in any way due to the high oil pressure(at the higher RPM's) and low output from the pump.

I wanted to disconnect it because the characterists of the motor oil when it burns is not very emissions friendly. Also the carbon build up on the rotors are very heavy in comparison to the premix. Another reason is i was thinking about using a Synthetic oil but i would probably remove the OMP alltogether if i do this. Thanks for the help

Also, would 100:1 be 16oz premix to every 16 gal fuel? I'm kind of lost there. I think I read somewhere about people premixing 1 oz: 1 gal fuel. Just trying to get a heads up.
Thanks,

for starters 200:1 is much too much oil for even strictly running only premix. and no there is no added strain on the oil meetering system by doing what ur doing

200:1 so I'm not sure why you're saying that...
and i use 50:1 1/2oz per gallon. just becaue it says it is reccomended on the bottle. so that is what i use but if it does not say anything on the bottel for recommended use i use 100:1

The OMP will not be harmed by pressure IIRC, because it is not fed by high pressure oil.
What I've done is left my OMP functioning as a back-up if I am stuck without pre-mix. I run 128:1 TCW3 on top of my OMP as a supplement and in hopes that it helps keep the carbon build-up off.
