29.2 MPG
I'm pleased, as this includes cold starts (15-25 degrees) in the A.M. in which my car's torque converter doesn't lock-up until nearly 10 minutes into my drive, meaning my interstate speed of 65 MPH would equal to 3k RPM until it locked up, bringing it back to 2600 RPM.
We do have winter blends here, I believe.
I'm happy. My mileage is starting to rebound back up to around 24-25. Also, I recently replaced my air filter, it was kind of grubby, and I ran a can of seafoam through the gas tank to maybe clear up some deposits that may be forming.
Are there other additives, fuel-injector cleaners that I might be able to try? Should I even bother? Oh well, Spring is on the way. Taking its sweet time, but it's coming.
About a year ago I asked the question on another website and somebody returned with an additive that is $80 and you have to use it every tank, not worth it in my opinion.
I have made this same trip in my LS430 Lexus and consistently averaged just over 26 MPG. The Lexus is a lot heavier vehicle with a larger engine.
I would like to hear experience of others on their MPG for 2008 Accords with both the 4 and V6 engines.
Some have said that I will have to wait until the engine is broken-in. But I think not. Today's engines are build on computer controlled machines and are almost what blue printed engines were like 40 years ago. So the break-in of a new engine is no longer an issue. At least that is my opinion. I would like to see other opinions on this.
That's my opinion of my 06 EX-L I-4 manual. I started getting great mileage from the beginning. While we haven't had many 08 I-4 postings here, it would seem that people aren't getting the mileage the previous generation achieved. I'm interested in seeing what happens when more folks post.
As for the V6... I don't have any experience with that engine but I don't blame you for being disappointed. Hopefully, the warm weather in the spring will help.
I'm very dissapointed with the MPG on my EX-L 4cyl. As I posted before, my two 4500lb Odysseys consistently get 22-24mpg on the highway.
My 2008 V6 has averaged 24.1 mpg since I bought it . My odometer is at exactly 1500
miles.
My best refill was 27.2 mpg on a highway trip of 250 miles. My worst refill was 21.56 mpg after heavy local driving with much stop and go.
I doubt if there will be much improvement due to break-in.
I have, in the past, frequently made the trip from New Jersey to Florida on I-95 (Not with my Honda Accord) There were times , especially in Virginia,on I-95, just south of Washington, D.C., when the traffic was worse than city driving. Also, I don't know
how far south you drive , in Florida, but there are times when traffic south of West Palm Beach is worse than City driving. Nevertheless I,d expect you'd get a lot better than 25
As a point of reference, if you were to get 29 H'way and 19 City as per the EPA numbers for Accord V-6, your trip would have had to be 93% highway travel over the full 1200 miles in order to average 28. You should be able to get 25mpg by driving the equivalent of 30% city ,70% highway.
At any rate, holew, I'm scheduled to make a trip from my home in Florida to New Jersey at the end of February. I'll post my mileage.
If you are only getting that kind of mileage with an I4, something is wrong... either with your driving habits or the car.
I can't remember... do you have an 08? At those speeds on the highway, you should be able to join us in the 40 mpg club with the previous generation Accord.
EX V6 08
411 miles, 17.7 gallons, 87 octane, 60% highway, 23.2 MPG.
Gas mileage suffered on more local driving.
I drive 85% interstate, at 75-85mph. All the driving is at high elevation (5500-9000 feet) and usually over hilly or mountainous terrain. It has been relatively cold (0 degrees to 25 degrees) and I am using winter blend 85 octane gas. Although I drive fast, I drive very evenly and I virtually never let the engine race. I much prefer to drop 10mph on a hill than to let the engine drop into a lower gear. I have 6000 miles on my 08 Accord.
Under these circumstances, I have consistently achieved between 24.5 and 26.5 mpg.; the average being right around 26mpg.
I purchased my Accord in September. Before it got cold, I was consistently achieving 26.5-31mpg (very dependent upon wind conditions and the amount of in-town travel). I would guess that my average mpg before the cold temperatures and winter-blend gas was 27.5.
Overall- I would say that I am satisfied, but not impressed. I am a more conservative driver than most, and I'm still not achieving the high numbers estimated by the EPA. On the other hand, I drive fast, operate at high elevations on hilly terrain and drive in a cold climate.
Also how many cold starts per tank? If your driving is all one long trip you will get much better mpg than if this is a week or more of daily commuting. Cold starts hurt mpg - even more in very cold weather. Do you let the car idle to warm up, or to defrost the windshield. This also hurts mpg.
What was your previous car and what did it get for mpg.
Also consider synthetic oil 0w20 will help mpg in the cold. You lose a couple of pounds of pressure in your tires for each 10 degree drop in temp, so make sure they are aired up.
You are driving in some of the worst conditons for gas mileage. I don't think your numbers are too terrible. Go visit grandma in the plains and drive 65 mph - you will be pleasantly suprised.
- Friend's '08 Civic 30 mixed - 35 freeway
- My '05 Accord hybrid V6 255HP: 30 mixed - 37 freeway
- My '02 Accord V6 22.5 - 26.5
- My '08 Accord V6 EX-L 24.5 - 30
Agreed with Dudleyr. Drive slowly and conservatively like Grandma one will get best MPG like Grandpa's.
1- Highway 32 mpg about 185 miles (based on thetrip computer readout)
2- My last tank of about 425 mixed miles (my bad, the light came on!) got 23.4 mpg..
3- The trip computer shows that my overall mixed mpg for the entore 2000+ miles so far has been 23.0
Shall we presume that you are talking about a 2008 V6 EX-L? If so, your mileage is virtually identical to my somewhat lighter 2004 V6 EX-L Coupe's with its smaller displacement and lower horsepower. That may be because of the more fuel efficient use of Variable Cylinder Management in the 2008 engine in the larger vehicle.
Local driving is about 21 to 22 MPG.
Some of the fuel has 10% methanol while other fills did not.
Would like to see other's experience with this same engine.
I expect and aim for my '08 V6 EX-L (with VCM) to 32 - 34 MPG on freeway like Parviz. It means with VCM its MPG is equal to that of an I4 (2.2 liters)
I have been driving my '08 EX-L daily to work now. All I get is power on top power. I shut down my CD this morning to find out if there are any noise, vibration or surge as the other guys have claimed. Nothing yet. Enjoy it.
I was so excited to see 32-34 mpg on the screen! Of course, when it is mixed mileage at the end then you hit the real world!
Are you sure you were not a novel writer in another life?!
I am expecting to get better gas mileage as we get the engine worked out a bit more. At a little over 2000 miles it is still just a baby.
I've been running just 87 octane. Have you tried any high test in your 6 and if so any noticeable differences?
Instant MPG 35, frequently 40+, sometimes 60.
As a long time Honda owner, I strongly believe my '08 V6 EX-L can get 33 to 40MPG if it runs straight on freeway for 4 to 8+ hours without much traffic interruption. Getting a decent MPG while listening to favorite musical tunes are the most satisfying experience does not it. I feel like the top King of Kings on the roads today while driving my very powerful '08 V6 EX-L and listening to my fan singers.
I do not know why some drivers keep complaining about the surge, vibration, etc. with their '08 V6. May be less than 10 cars/ owners on Edmunds among almost HALF A MILLION Accords sold to the U.S. every year. When Honda says PZEP it means PZEP. I love every single buttons in my Accord. Honda means business and scientifical accuracy.
Shame. I love my Beetle TDI (160K miles, regularly get 46MPG) and was really looking forward to upgrading to an Accord diesel.
I am planning a road trip next week and am curious what MPG change this will make. I'll let you know.
When you got 32-34 or 36 mpg on uniterrupted freeway it meant your mpg was equal to or better than that of an Accord I4. It's very good.
VIET, a very happy EX-L V6 owner, also a Honda cars/ motorcycles owner for over 40 years.
Other then the first tank I averaged a steady 24-25.5 in mixed driving up until about 3k miles. Since then it's been a steady 25.5-27 in mixed driving, like someone flipped a switch.
I get a pretty regular 390-410 between full and the low fuel light.
That's with chunky snow tires and freezing temps daily. Hoping for close to 30 once summer comes.
The tank size won't tell you your MPG. To find that, reset your trip odometer at your next fill up. Drive, refuel when you have used at least 3/4ths of the tank, then refuel, taking note of miles driven.
Divide the number of gallons you pumped the second time into the number of miles driven. For example:
300 miles / 10 gallons = 30 MPG. Do this and you won't be guessing how much fuel you used.
MPG depends on traffic condition, driving technique, etc. When car is aging one must maintain/ tune -up car to keep it in top good. I got average 25.5 MPG on my second tank. On the third tank (600+ miles), it was very promising. I can see a big change. It means my average MPG (on car's trip computer) shows average 27 to 28MPG while running on freeway. Instant MPGs are 30, 40+, many times 60MPG. I love the computer that tracks the instant MPG and many other digital things. Probably I am a hi-tech & math guy so I love accuracy.
As a long time Honda cars/ motorbikes owner for over 40 years I am strongly convinced my V6 EX-L mixed MPG will be good as a small 4 cyclinders Honda (30+ MPG). Please check with Hank119, McpdJohn and Parviz who own EX-L V6 in these forums to exchange experience. My old '95 Accord I4 @ 253K miles got good MPG as day one. it depends on how you take care of your car. Thanks.
Please do not use A/C much. Do not open windows while driving on freeway, etc,. Many factors involve MPG. Good luck, Ma'am.
I made the same trip again this week but and the milage was better because I started with less in the tank and finished with more in the tank. I'll confirm the milage again after I consume a few more tank fulls of gasoline.
Hold on to your TDI for another year or 18 months, and you can move on to an Accord diesel (though have you seen the Jetta Clean Diesel Sportwagen being released this fall? Hmmmm...I have a deposit down on that one).
If I may ask, what was your previous car, and what mileage did you see from it?
