Improve fuel economy?

Alright. So I drive a 2007 Honda Accord Coupe EX 4-cylinder with an automatic transmission and recently after a fill-up, I got 28 mpg. the driving consists of 85% highway and 15% street. I'm a bit disappointed and my ultimate goal is to get 35-40 mpg. this is how i drive:



- since i drive an auto, i let the first gear go up to 2500 rpm. 2nd gear go up 2250 rpm, 3rd gear 2000 rpm, and then i let go of the gas pedal which drops to 1500 rpm @ 40 mph.

- merging into freeway- 2500 rpm first gear, 2750-3000 rpm second gear, 2500 3rd gear, and gradual speed up until 65 mph @ 2100 rpm

- i used 87 octane gas

- i use cruise control and drive at 65mph on the freeway even if the traffic flow is going at 75 mph

- i start braking at a far distance so gradually slow down the car rather than extremely fast braking

- i gradually accelerate slowly and then i let the car pick up until the speed limit even if it takes a long time.

- i warm up my car until the tachometer goes down to 1000 rpm (which takes about 30-45 seconds to do so. sometimes 1 minute)

- the oil is pretty new. about 500 miles have been put in since the last oil change.



also i don't carry anything but myself inside the car. no cargo, heavy stuff in the trunk etc. i use the air conditioner when i am on the highway and traveling at 65mph but i keep the fan speed at its lowest. i open the window whenever i go at speeds below 45 mph to avoid using the air conditioner.



so anything i'm doing wrong here? should i go 55mph on the highway instead of 65 mph? my ultimate goal is to get 35-40 mpg in this car.



no, i do not want to add performance parts like a cold air intake to improve fuel economy.Improve fuel economy?
I own a 2007 accord as well. Mine is a sedan and the best Ive been able to get is in the low 30s including AC on.



Since yours is a coupe, yours would probably get around 35 tops. Please check out this link below for average fuel economy:

1) I would recommend keeping it below 2000rpms as much as you can

2) the sweet spot for gas mileage is somewhere inbetween 55-60. Seeing as how most city streets have lower speed limits than this, this may or may not be doable for you, but the closer you get, the better.

3) you've already got traffic figured out. Time your stoplights and try not to even brake for them. With an automatic transmission, as soon as you hit the brakes, it goes into a different mode so only applying the brakes when you need them is the best idea. People that hit the brakes once every few seconds are wasting alot of gas.



Anyways, I hope this helps!

Good luck with your fuel mileage!Improve fuel economy?
mph makes no difference to the fuel economy. on the freeway keep your rpms low by making it to a high gear and driving in low rpms at the safe speedlimit. On the freeway set your cruise control at the lowest possible rpms for your highest gear. this will increase your fuel economy by alot. I drive a silverado and get 12 mpg. be happy ith your current fuel economy.Improve fuel economy?
shorten warm up idle time.



accelerate a little quicker. you burn more gas accelerating, than you do when cruising. and cruise control doesn't save gas.



maintain proper tire pressure and front end alignment.
