My 4th fill up tank, I got 31 MPG. 80% highway and 20% stop and go trafic. doing mostly 65 mph on the highway. and no jackrabbit driving. The MPG was calculated using the refuel method and using the SCANGUAGE. Both showed the same result. On the highway at 65 MPH, I got as high as 44 MPG steady for a long flat stretch, when the wind is helping the car from behind I got 66 MPG, when the wing is working against me, I got 26 MPG. But the average on pure highway driving is around 36 MPG with speed not exceeding 70 MPH. Pure stop and go trafic, without aggressive driving will get you only 25 MPG. These numbers are based on my own experience, I could improve on these numbers if I take it slowly all the time, but I could get worse than these numbers if I drive aggressively. One thing to remember, this I4 likes to be revved, to extract those 190 horsepower, but at the same time doing so will get you a marginal MPG in the range of 24 or 26 MPG.

Your mileage is excellent - especially as you point out that the 190 HP engine develops its maximum power in the higher RPM range. A lot of people say the ideal combination is the 190 engine w/5 speed

Recent fillup.
397 miles 43.6 mpg. Needle 1 tick under half tank. Filled at same pump, same way, same day. 43.2 mpg on scangauge.
Way there ... 37.8 mpg 40 to 48 degrees slight headwind, 65 mph.
Way back going for max mpg. Tailwind, 1600 ft elevation drop over 200 miles, dropped speed to 55/56 mph, ideal temp of 65 ... no a/c, but still warm for efficient running. 52.1 mpg.... first time over 50 mpg. (yes I coasted when it did not slow me down)
32.9 mpg lifetime, 35.2 mpg last ten tanks. 2007 se i4 mt. 0w-20 mobil one, 40 psi tires.

....congrats from our left coast. Outrageously efficient numbers - such as yours above - cause I4 consideration to enter the equation as the 6M ages (gracefully).....
well done.
best, ez....

How the F is this possible? I have avg 19 on my first tank and 22 on my 2nd. 85% side streets and 15% highways

ez... still jealous of your 6m. Mpg drops off faster with the 5m than the AT. Case in point my 25.1 mpg number for a run at 80 to 85 w/ aggressive driving. I think an AT would have done better at those speeds. An MT is hard to beat a lower speeds/revs though. 6MT is the best of both worlds.
gleen6191.... it is not possible with 85% city unless you are an extreme hypermiler ... much more than me. You also need the patience to drive slowly and steadily. Wayne Gerdes gets 59 mpg in city driving with an MT I4 Accord. He actually turns off his engine while coasting, and he coasts a lot. He drives real slow as well. Google him.

I think your MPG numbers are little bit more on the optimistic side; but don't get me wrong, I get the same MPG and better if I use different tricks used by hyper-milers; like switching gears to neutral when you're helped by tail wind or by sloped road, or to move the car from 0 to 25 MPH you need to adjust the throttle to not open it more than a quarter turn, just to get the car to move from stand still, or up shifting earlier than normal, or coasting from one red light to another, or shutting off the engine at red light,,,, All this techniques can help you achieve a better MPG than what the EPA states for any particular vehicle. One thing I do not agree with is shutting off the engine when you’re costing in the highway, this has serious consequences, all hydraulics system (brakes, steering wheel, etc) are operated using the engine, if this one is shutdown the brakes get hard, the steering wheels get heavier, or get locked, this will impair your aptitude at controlling your car, this is not counting case of emergency maneuvers. I think with some conservative driving attitude anybody can get 35 MPG on the highway for the 2008 accord I4, 5speed MT, and 25 MPG on stop and go traffic. I own both 2008 accord I4 MT, and 07 Odyssey V6.

Tricks like shifting into neutral may be ok with the MT but I would not be inclined to do it with the AT - I believe the owner's manual advises against it. I absolutely agree with you about shutting down the engine while driving - VERY dangerous. Have you ever tried steering and stopping a power equipped car with the engine off!? Have to be "Ahnold" and:
Here is a question. If you are coasting with the engine off and are hit, will the airbags deploy? I suspect not since isn't the system dependent on electrical sensors?
do you not also lose the anti lock braking?
I really don't know - haven't tried it and don't want to!

I have never coasted without engine either, but I think the scariestt thing would be turning the key too far and locking the wheel while driving.

Coasting without the engine (by using neutral transmission setting) may not only be dangerous, but may also actually consume more gas than coasting with the engine. With modern technology, during coasting with the engine, the fuel injection to engine cylinders is completely switched off (I am almost sure that the honda car engines do that) because the engine will continue to rotate even without any power being produced by the engine. On the other hand, during coasting without the engine, some fuel (even though small) will need to be continuously provided to the cylinders to maintain idle speed.
