Pontiac, Michigan to Bristol, Tennessee.. 658.3 miles on 13.795 gallons of fuel for a little over 47 mpg!!!!!
First leg, Pontiac to Cincinatti(actually about 10 miles in Kentucky) 306.3 miles on 7.202 gallons for roughly 42.5 mpg. Used Cruise Control exclusively, set at different speeds depending on traffic. 55/60/65 mph probably mostly avg 62 mph.
Avg mpg gauge showed mostly a bit over 52 mpg, so I was disappointed with (hand calculated) 42.5 mpg.
So, the second leg from Erlanger( I think) Kentucky to Bristol, I decided to drive without cruise control. Held as close to 60 mph as I could. Holding my foot as still as possible AND coasting in neutral on any downhill stretches I could.
352 miles on 6.593 gallons for 53.38 mpg.
Extremely pleased with results!!!!
Air conditioning on the whole trip and 35 psi in tires. Under 1500 total miles on car.
What an automobile!!!!
