1976 280 Mph
I'm a newbie with a recently purchased 1976 280 - high mileage, of course - in good overall condition. I had some minor engine work done (it had been sitting a long time) and it runs great! BUT, it sucks gas! I realize that a car of this age and weight won't get what modern cars get, but I'm wondering if there's anything within reason tht I can do to improve it. Since my odometer only works when it wants to, I can't get an accurate figure. At this point, I don't plan to get the odomter working. Any ideas? Also, do I need to run 91 octane in it? Any input would be appreciated!
Thanks
