I work on a few blown alcohol injected drag race engines.
The gear box on the blower to drive the rotors needs oil to lubricate it.
Some are trying to convince me I should use 2 stroke oil as if the oil leaks past a seal and contaminates the fuel, 2 stroke is designed to burn.
While I agree, clean burning is a prerequisite of 2 stroke, so is being able to lubricate4 roller bearings in a very low oil, high fuel environment, and they will be formulated with those parameters weighing heavily, but I expect 2 stroke is NOT formulated to lubricate gear boxes.
My concern is the relative effect on octane rating of various oils on methanol in a failed oil seal situation. Does anyone know if any 2 stroke and gear oil manufacturers produce data about the oils octane rating and the effect it has on methanol's octane when mixed.
I would also like to know how good 2 stroke oil is at lubricating gears as this would not normally be a parameter when formulating it.
I really can't see me changing, but I am concerned some meat head is going to influence one of the car owners to change the oil. I would really like it if I had data, not just supposition to counter their arguments.
I think I already know that in this quest, I am shovelling it up hill with a pointy stick.
