I am planning on getting a former bus, as in city or tour bus, and making it a motor home, and i belong to a few groups for that purpose. Some of these folks that convert the busses into motorhiomes scare me, with questions like 'what do you mean by a 'three point turn'?

Anyway, these bug critters run Allison trannies (various models) and Sheppard power steering....so the discussion of what fluid to run in them came up.

Appaently you can use ATF or 10w40 motor oil...not together fo course, but drain, flush and pick one....and off you go!

I don't think power steering it too picky on type of ATF, but i have NEVER heard of using motor oil in a hydraulic application like this before! And as to the auto trans....come on, put 10w40 in instead of Dexron???????

Anyone have any experience here or know what base these fluids run....ATF cleans, oil well, mekaes thigs oily and dirty....gotta be different from molecule 2 on up the chain, right?
