You are in the Honda Accord
What is this discussion about?
Honda Accord, Fuel Efficiency (MPG)
#2853 of 2937 Re: Our Accords MPG [nw1997]
Jan 24, 2012 (3:11 pm)
I have a 2005 four cylinder honda accord 5sp auto with about 180,000 km or about 112,000 miles with all original spark plugs and no tune-up has been done yet. In the winter months, here in Toronto Canada(cold and snowy), I get about 19mpg city and about 30mpg highway at speed of 65-70mph. I would like to know if I change the air filter(replaced previous one a year ago) and spark plugs with NGK Iridium Plugs, how much will my mpg increase? My city mpg seems low and even in the summer months, I barely get 22mpg. I would like to know if changing the plugs will make a difference.
Secondly, I do not believe for one bit those people in this forum that are achieving over 35mpg. Baloney. They are probably not filling their gas tank fully. What I mean is when you fill your tank, fill it up until you see the gas and your tank is completely full, drive, record the km or miles driven, and fill your tank up to the top completely again. I can assure you that are stating the incredible gas mileage, that when the pumps shuts off, I can pour 2 gallons more until the tank is completely full.
On the highway, if you have a light load, with summer driving conditions, flat land, driving at 60-65mph(100-105kmph) you can get at the max 34 mpg and that is with the 4 cylinder model UNDER IDEAL DRIVING CONDITIONS.

thats baloney. In order to get that kind of mpg, you would need to drive 90% or more freeway miles.

Since my word is baloney, it won't do much good to comment on the spark plugs. Good luck.
34.8 mpg lifetime mpg and dozens of tanks over 40 mpg. 10 consecutive tank rolling average once hit 39.8 mpg.

Ok, then why would the government rate the car as 31mpg highway(epa), on fuel.gov. Your practically driving a hybrid with that kind of mpg. If my lifetime mpg was 34.8, I know I would be the happiest person in the world. Is their any mods on your car and what spark plugs do you use? I need to get my hands on something to boost my mpg.

Go back and read previous posts - lots of info on getting better mpg. Hardly a hybrid - a Prius can average mid 50's pretty easily.
In a nutshell - plenty of air in tires, 0w-20 synthetic oil, slow down, drive smoothly, drive a stickshift, combine trips so you are warming up your engine less, don't accelerate too fast, go fast around corners so you don't have to accelerate back up to speed etc. etc.,
The government rates the car at 31 but on the old test it was rated at 34 and that was after a 22% reduction of measured mileage to make the numbers easier to match. The actual highway test number is 43.5 mpg for the Accord - this is on the course with a warm engine and an average test speed of 48 mpg - can't remember max speed off the top of my head but it is around 60 or 65.
You are due for plugs, but putting new ones in won't change your mpg appreciably.
#2858 of 2937 My 2011 Accord MPG is disappointing
Feb 04, 2012 (8:04 pm)
This is my 10th Honda and I am really disappointed. Had a 2007 Pilot, got about 17mpg. Last year, bought a 2011 Odyssey and an 2011 Accord EX 4 Cylinder. My Odyssey gets better mileage on trips, 27 to 25. For running around town, etc, the Odyssey gets about 21 while the Accord only gets 19-20 mpg. I should get more than 300 miles per tank. My 1996 Accord (stick) got 36 mpg on its last trip at 160,000 miles. I have taken it back to the dealer who has said that there is nothing they can do because the check engine lights are not coming on.

The real fuel ratings for the accord were 34 MPG highway and that's being really conservative. Those were done with max speeds around 65mph. With an average speed of 60mph. With the new fuel economy testing accounting for different weather conditions, use of AC and other factors, the number for the accord is NOW 31MPG. Yes, I do believe its possible to achieve up to 35mpg highway at 60-65mph, but I just find it astonishing when people state that they get 27-28 mpg city when the car is rated at 21mpg. Also, then their are people claiming to get up to 40mpg highway with a full trunk, full loaded car with 5 passengers and speeds up to 70mpg. Realistically, for a 2005 Honda Accord 4 cylinder, driving on the freeway you can get 30-33mpg.

I get 40 mpg all the time, but not too often when driving 70 (only with a tailwind or ideal conditions then). I very rarely have a tank under 30 mpg in the summer. When it is below zero out and I drive a whole tank in town I can get as low as 20mpg. MPG did go up a trifle for the 2006 model year. also a stick shift helps a ton for getting better mileage.
Also the old number of 34 mpg was already dumbed down by 22% from the actual tested number (per EPA testing procedures). Now that it has been dumbed down to 31 mpg it is pretty darn easy to beat.
Just Today I got 37 mpg going 65 mph into a 15-20 mpg headwind with temps ranging from low 20's to upper 30's (better mpg at higher temps)

Is it possible to get similar MPG from 2010 I4 model compared with 2011 model. I am getting 21-22 mpg in all city driving. I am trying my best to get close to 25mpg but no luck so far. I am kinda disappointed not to get 2011 model or optima.
Feb 17, 2012 (10:36 am)
With ideal conditions, probably in the summer, you can get sometimes 25 mpg city, but its going to probably be 23mpg most of the time. In the Summer, I get 23-25mpg in city driving and 19-21mpg in the winter months. This is 2005 I4 EXL.
