You probably ought to run Av gas just to be safe. Those high compression tractor engines...probably 8:1 and running outrageous RPM"s...in the three thousands can"t be abused with regular pump gas.....likely will self destruct.
Now, I don"t have a book or manual or calling from a Higher Power to hand down advice. But, unless you"re pulling the guts out of that 706, I doubt you"ll notice the difference between 87 and 93 octane gas. Ten to twenty cents a gallon isn"t all that much if fuel cost is all you that are considering.
8:1 compression is not high and three and four thousand rpms isn"t high either.......higher than what old tractors operated at....but still not high rpm"s.
High compression starts at around 9.5:1 and high rpm"s come in at 6,000 or better......neither of which you will find in working tractors of any vintage.
I wouldn"t buy 87 octane gas just to save 20 cents a gallon......but to use 93 octane gas because I thought it would destroy a 6 cylinder tractor engine due to high compression and rpm"s.....I think not.
