Hey there. I own an 05 accord lx-v6, its got about 94k miles on it, well taken care of. It has such trouble with gas milleage. I bought it in Phoenix from my bro and drove it to Nebraska and it gave me great mileage. When we arrived here I noticed the mileage got worse. I changed the oil, check tire pressure. I then changed the air filter and saw some improvements, but they went down after a few tanks. Finally I switched out the stock spark plugs as well, and still nothing. Oh btw I took it to the dealership to do a diagnosis and they said that it meets honda specs. Right now since its winter its getting me about 190 miles on a tank of about 15-16 gallons(17.1 to be exact) Any suggestions

I may be wrong and there are other issues with the car, but I do know that a warm car and warmer weather allow a vehicle to get better mileage. When winter comes to NE and the north where I live as well, I expect the drop in mileage. You also might change the way you drive. For instance, they say that the newer cars don't need to warm up. I agree with that but I find I get better mileage by taking off slower and letting the car slowly get up to speed until the car gets warmed up. Then I drive normally but I allow more time to get in to traffic. I would wager that if you moved to Phoenix and started checking the mileage it would greatly increase.

Car dealers and manufacturers don't publish the cold weather mileage on the window sticker. Tests for mileage are done in warm environments.

Good luck with the car.
