Gas Mileage Decreasing/Changing
Hey everyone, I have noticed that a lot of people are claiming that their cars have all decreased in mileage. Depending on the amount it has decreased and where you live the problem believe it or not may be TIRE PRESSURE. My car (Mazda 6) went from 23-25 MPG to 17 MPG all of a sudden. I checked air filter, after market exhaust, different gast station. Well finally a good buddy of mine told me to check tire pressure. I was 5 lbs low on the front drivers side, 4 lbs low on the back drivers side and 2 lbs low on the passenger side. I am now back up to normal Fuel Economy. The cold will affect your tires that much and its also dangerous to drive with tires that far out of whack so if you suspect something go check your tires.
Hope this helps some of you!
