Not that octane means much to a Model A, here Reg is usually 85 or 86, Extra is 87 to 89, & Premium can be 90 to 92.

Part of the reason octane ratings are a couple points lower in NM is the altitude. Seems 86 in your state is equivalent to 87 out here in Whackofornia. In any case, the A seems to run fine on anything short of olive oil.
