Are all IH gas engines from that era as sensitive about the gas octane?
I don't know what octane Dad ran in his 460, but then he passed away in '84 and maybe the farm gas was better then. Also my 240U is the same age (1958) and should I be adding an octane booster to it or maybe using the same 91 octane we use in the car? (I do have an owners manual for it, but I seem to have mis-placed it for now.)
Another dumb question... can the timing be changed enough to allow for the lower octane?
