I have a 2008 honda accord v6. I do mainly city driving from school which is only 1.5 away. i drove 150 miles and lost a little bit more than half the tank and i havent really even been gassing it. Is this normal. I did put fuel injector cleaner in when i filled it up.
You need to take a trip to recondition the oil. Water, fuel and contaminates build up from short trips. 30 minutes to an hour of highway driving burns them off. The PCV and emissions system get dirty on short trips and that can affect mileage.
