I have a 2006 Honda Pilot 2wd with 54000 miles. Its gas mileage dropped from 21 to 17 recently with the same driving habit and same route(from home to work and some city and some highway). I changed air filter, checked air pressure, changed transmission oil and even used gas system cleaner. no help …

Do you always buy your gasoline at the same place? A 10% ethanol mix can lower your fuel economy.

If the vehicle is not reaching operating temperature, it won’t get as good mileage than if it does get fully warmed up. In summer weather, it is difficult to notice that the engine is running too cool because you aren’t using the heater. Check the temperature gauge. If it is not reading in the no…

Does the drop in MPG correspond to increased use of the AC?

Since I purchased this Pilot(brand new), its MPG has been 20-21 or more. It dropped to 17 just recently. I changed engine oil at HTB recently, before I changed it in Firestone. I guess the engineer oil is the possible problem. Another guess is the brake pads which was changed not a long ago. Thanks …

I have been using 87 with 10% ethanol mix and it should not be a problem except the gas quality changed recenlty. Thanks.

I am in Texas and has to use AC all the time, I do not think lower MPG is related to AC usage.

Thank you all for the help and suggestions. This pilot has been running at 20-21 MPG for over four years. The one tank of gas (16 gallons)could run 330-340 miles. Right now it runs 290-300 miles with about 17 gallons. I use this Pilot for work and drive on the same road and no driving habit changes.…

Even though the car companies say (iridium) spark plugs can last 100k miles I don’t trust that they always can. So I think it’s a good time for new plugs. 4-5 years is a good time to change coolant, thermostat and maybe radiator hoses too, especially down in Texas. Cruise a few miles on the high…

I will try to change the Spark Plugs, coolant by my own this weekend and test my brakes as well. I will update the MPGs thereafter. By the way, what is the thermostat? Can I change it by myself? Thanks again

I did not know this, but I will check to see whether temperature is in the normal range. But what is the normal operating range? in the middle of the meter?
