I have 02 accord ex 4 doors, 70K and using mobile one engine oil for honda, with the mobile filter as well, but the gas mileage is about 18 mile in town, and highway is about 27 in town. i check the tire pressure is 32 psi on four of wheels. May I get some idea about the problem of this car?

 

i dont know what mpg f23 6th gens are suppose to get ... when is the last time you replaced your o2 sensor? when was the last full maintenance: plugs, wires, cap/rotor ect ... and the way you drive obviously makes a difference as well

 

Are most of your trips 6 miles or less?
Kansas can get pretty cold this time of the year and you could be running with the engine never really warming up.
Check your tire pressures
Research when the last time tune maintaince was performed
And think about having the primary O2 sensor changed out. Although only 70K, the 6 years it took to get there could be problamatic. 11K/year is very low milage/use and the O2 sensor could have issues. When they get lazy, they can't react fast enough for changing engine conditions and you start loosing milage and performance (it's all about 'counts')

V6?

if so it's about normal unless you are easy on the throttle

 

Yea that sounds about right for a V6. I-4 probably not.

 

it's four cylinder only

 

is there a check engine light on?

 

it's not on....

 

are your rpms correct if it is an auto? do you get good heat from the engine?

 

i think so, it is normal

 

although you don't have a check engine light on I recommend you check your EGR. I just had mine fix and my MPG is much better.

 

sorry, what is EGR?

 

EGR
Exhaust Gas Recirculation valve

Hope this helps
