When I purchased my C-Max in 2013 I decided to see if I could get 600 miles on a tank of gas. I did it. That was my last 600 mile tank of gas. At that time my car had 20K miles on it.
Now I am approaching 240K miles. Can it still get 600 miles on a tank of gas?
I should know tomorrow. Right now I am at 9.46 gallons used with 460 miles completed. The average mpg so far this tank is 48.4. These are all highway miles. I am driving about 57-58 mph on average. I also have a full load in the car. Tire pressure is 50psi front and 48psi rear. 0W20 oil. Tires are non low rolling resistance.
It may be my last tank in this car period as I am planning to trade.
