I just attended the 16 chryslers at carlisle and finally after 8k miles after beING restored I calculated mileage! First off I have a 69 dart with the numbers driveline. 340 stock 727 and 3.23 suregrip. I'm running a 255/60/15. I'm only averaging 10mpg running at 60mph. I feel that's poor mileage and was wondering what yall are getting. The car runs great but is there something going on with me achieving these numbers. I'm running 93 octane also. Thanks in advance
