Since AI cleans everything nicely, does it affect OMP/Premix lubrication?
The issue with most premix brand questions is you never know if it's "better" or "worse" until you tear everything down to inspect. Even then, there are many variables in the equation.
i don't have any firm answers but i do have 5 years experience w no OMP and premix on a single motor. i ran no OMP and 1/2 oz Walmart 2 cycle on the street, 1 oz on the dyno. pump gas and around 900 cc.min of meth as AI injectant.
my motor slowly and constantly built compression over the 5 years. i decided to dis-assemble it for analysis. (i do a 6 page spec sheet on all my motors so i had a base on which to compare).
just to be clear, the motor was 100% when i decided to do some comparative work on it.
the housings were fine... (Atkins apex seals), the side seal gap had opened .001. the rotors were carbon free.
so it seems to me that premix works without an OMP. i see no problem w combining the two as long as you are not using crankcase oil. i would start by continuing the premix ratio and then check the plugs. my guess is that it would be best to continue the premix ratio w the OMP.
