- 1972 Mach 1 Q Code with factory ram air
Ok, this may be a dumb question but, i have been running un-leaded in my 1972 mustang (that is why i bought a 72, i didn't want to mess with lead additives). I was looking at the 72 owners manual to see what octane was recommended and it says that all 1972s are designed to operate on "regular" gasoline. To me, regular means leaded. What should i be using?
Thanks.
Thomas
