I usually put 87 in my car and a few days ago I put in 89. My MPG decreased. I fill up my car usually around 311 miles on the tank. This time I had to refill at 260 miles. The arrow is always at the last tick before E. Anyone have any idea why the MPG decreased?


Thanks,
Roman

Hi Roman,
1. An incredible number of possible reasons - beginning with your driving style to bad gas.
2. I'd like to advise you to have your fuel tank filled not less than 1/4. While cornering or braking your fuel pump will be "dry" and go south soon.
Good luck,
