I run pump 87 in my 69 318 all the time, doesn't seem to care. It's my daily, so the cheapest gas I can get is the best gas. When I've left the car at home while I'm at school, I go find ethanol free to put in it, just to help the shelf life of the fuel and the rubber from getting eaten, but I'm not completely sure it does anything, just a little placebo peace of mind at worst.
