No oil warning comes from the OMS Pump itself. It has a sensor that determines that oil is flowing. I would recommend you test the alarm circuitry, and do not run the motor until you determine if it is indeed mixing oil, or not.

An easy test is to fill the oil tank to the top and run a couple of tanks of 50::1 premix thru the motor. If the oil tank needs a qt of oil to refill it, the OMS pump is working.

Was following this post and was curious if replacing your VRO's was the fix?
