Hi everyone, I have a 2001 honda accord ex V6 and am experiencing horrible gas mileage, it has gone from 330 full tank to about 220 miles. My car has about 120,000 miles on it and I have already replaced the spark plugs and air filter and changed the oil and also had the fuel injectors flushed and it hasn't helped can someone please tell me what else could it be???

 

have you replaced the O2 sensor or the fuel filter? also check your tire pressures.

 

Too many dead hookers in the trunk?

There is no fuel filter on a 6th gen V6.

 

Make sure that the rear brakes aren't dragging

 

My bet would be the 10% ethanol mix gasoline that big brother makes us consume these days. Worse mpg means more gallons of fuel that we burn, which provides more gasoline taxes to our federal and state governments. I get about 24-25 mpg in the city with regular gas, and only 21-22 mpg with the 10% ethanol mix.

 

my mileage with the E10 is around 23 city and 34 highway. dunno about anywhere else, but here in Upstate SC, every gas station now has E10, even the old full service exxon garages have it....bleh
