For the past few weeks and 1459 miles, I have kept a log of fuel & mileage at each fill-up. After odometer correction, it used 75.1 gallons in 1459 miles, for an average of 19.43 MPG. MPG ranged from 18.7 to 22.6, but most fill-ups were 19-20.
Driving was about 50 per cent interstate, 40 per cent "town & country" (country roads & very little time sitting still), and 10 per cent heavy traffic.
The car is: 62GT; 289 motor; T85 tranny; 3.54 rear gears (2.55 final drive in OD), and EFI with ECU controlled electronic ignition.
Gasoline used: locally concocted 87 octane, and at least one pump said, "contains up to 10% ethanol".
I can live with 19.43 average, and credit the EFI with the tighter range of MPG, since it seldom varies much, no matter the driving conditions.
