So I'm wondering if I have a lead foot or something, I generally am getting 17-18mpg (mostly city short trips) I try to baby it and its no different and I mean to the point people pass me in anger lol.

Freeway seems to be 19-22mpg range at 65-75mph, cruise/non majority flats no hills. Although when I drove from TX to MD about 1800miles, I did see 24ish.

Is this what I should expect or am I just re-re on the 6MT? Car currently has 10k miles (2010 SHAWD 6MT) has had 1 oil change, currently says oil life still 50%. Lemme know if more details are needed.

I get about 24 in the summer mostly suburban driving. 21 in the winters. I get about 27 on the highway @ 70 mpg (I try to get good gas mileage). 2010 shawd too. If I start hitting it, I get about 17 mpg.

Heavy in-town driving can really hit the mpg. I have a 16 mile, one way commute. Most of my car's miles are on this drive. About 6-7 miles of the drive are suburban/urban secondary streets, the remainder freeway. I try to drive rationally, but not like a granny, and I occasionally will run the car through the gears on on-ramps, etc. My Trip B average (which I don't reset) is at 25.5, and as the weather warms up will get up to 25.6 or 25.7, until it turns colder again. I've seen as high as 28-29 on longer freeway trips.

One thing I do is to turn the A/C off when I don't need it. If your HVAC control is on full Auto mode, it will run the A/C even in cool weather if the system detects excess humidity in the car. Having the A/C cycling in heavy stop and go traffic will really hit your mpg. I also use the cruise control on the freeway whenever possible.

I know my 09 only had a 5AT, but if I drove sane I would get 20 around town in suburban driving and then maybe 24 on highway. I would expect the 6AT to get maybe 1 MPG better.

Ever since I moved to be closer to my office, I have a 5 mile city commute. MPG is not, about 16.5mpg if I'm lucky, though it's close to the EPA claims of 17/25.

Now that I recently added a roof rack, I suspect I may have lost 1mpg.

When I had a mixed city/hwy commute, I got about 23mpg. Last time I checked, my trip B computer, which I never reset, is at 22.9mpg.

MPG depends heavily on how aggressive your driving is, any hills/inclines, summer/winter blend, start/stop traffic, etc... Too many variables.

For a 305hp AWD V6 near 2 ton vehicle, mpg is not bad. The 6MT is definitely not tuned for economy; the 5AT in the 09-11 4G has a higher EPA claim of 18/26.

In my 09' with bolt on's (HFPC, catless jpipe, lightweight pulley & catback), even on long stretches of highway driving 100+ miles, I never averaged more than 26mpg. In my 12' with the same bolt on's minus the catback and on a recent 27 mile trip with 4 of them being suburban I averaged 29.1, with mpg climbing until I got to the city. In the city I average 14-17mpg; lots of traffic and stops.

KeithL

Can't believe an extra gear would add 3 MPG on the highway, but glad it makes some improvements.

Six Shifter

consistently returned 27+ mpg (highway) miles, which was basically over 96% of the driving. 67 miles to/from work each day ... all freeway.

IrishTR

Someone mentioned the auto climate controls, I'll give those a go next as I do leave it on auto - 70 all the time.

But yea my 1 one way commute really went down to nothing maybe 5-10min drive tops double if I gotta take the kiddo to school in the mornings. So I guess I'm ok just wasnt sure if it was me or something with the car I should be concerned with, I know she's no Hybrid Civic bought thought it was a lil low.

Either my mileage will drastically change after my first oil change or I need to shift at 2k rpm. I commute suburban driving with a few stop signs and 2 lights for about 6 miles on my drive. 3 miles of highway is also included. Overall I average about 20mpg on a tank. I had two longer drives on rural two lane roads with minimal stopping and average speeds of 45-60mph and my mileage on that tank rose to about 21.x mpg. I had one tank that showed an average of 23mpg but I'm pretty sure the pump shut off prematurely as the fill up on that tank was lower than the rest.

Here are my stats so far.

I think the car's computer is more accurate overall for gauging mpg than the manual calculation method, for the reason you just noted. Pumps shut off at different points depending on how quickly the fuel is flowing, temps, etc., even if you always use the same pump at the same station every time. You simply can't be certain that you are always refilling the car to the same level every time.

I suspect some of the mpg disparities among the posters above may be due to short commutes. If you're driving only 5 miles each way, the car has very little operating time under ideal conditions. The first mile or two is warm-up, when mpg really sucks.

amill

The computer usually reads within 1/10th of a mile of the manual method. The only reason I know the one read was high was because the computer was off by almost 2 mpg compared to the pump. That is the first time I've had that happen in the 3 years I've been tracking my cars mpg, so I don't consider it an issue.

Six Shifter

You can if you never, ever stop when the auto shut-off clicks. I always have, always do, and always will top-off ... which in the case of the TL meant sometimes getting close to 3 gallons more fuel into the tank after the pump clicked. In my CL it was close to the same, in my Vette it meant about 1 1/2 gallons, and in my current S5 it's normally less than 1/2 gallon ... but I do always try to use the same pump once I find one with handle tension that allows for the application of low pressure to achieve the slow-flow fill to help avoid overfilling/over splashing. Probably one of the reasons that a 500 mile range was not unheard of during my years of ownership.

Mr Marco

yep...same here. Wife gets another 5 mpg over me.

KeithL

I agree and My TLs were worst since they had smallish tanks. I was always able to get another 1+ gallon in. On my M37 with 20 gallon tank I can still usually add another gallon.

putzld

I have the 2010 6MT and my 25 mile highway and 4 mile city driving commute gets me right around 25 mpg. City driving can drop it quite a bit.

Incidentaly I did notice a small increase in MPG once I lowered my car with H&R springs.

Ziffle

I just put the third tank of gas in mine and the computer is showing 19.4 mpg. I drive about 70 percent city/30 percent rural state routes. I find it incredibly hard to shift at low rpm's, so all things considered not too bad so far.

TimbukTL

I average 19-21mpg in town for a 6-mile one-way commute. Trip B (since I've owned it) shows 21.4 over 4250 miles, including a Minneapolis to New Orleans trip at around 80 mph. I've thought about keeping it at 55 for a long hwy trip just to see the mpg, but what fun is that?

OTOH, our 2012 Odyssey, with a 3.5, 6spd auto and cylinder deactivation, showed 35mpg on one 60-mile trip at 55 mpg. Frustrating that it weighs more, runs on regular, yet gets better mileage than the TL. Of course, not nearly as fun to drive!

I think I've been in the 20-22 mpg range since I've owned my car. I drive mostly on the highway but generally at 75 mph or faster. I also can't help but push it close to 6700 RPM's at least once a tank if not more

oscars2212

For true city driving 17-18 MPG is about what I get. For highway driving my MPG goes up above the EPA estimates, around 28 MPG if I keep it around 70.

George Knighton

73,000 miles here on a 2010 6-6.

The car's lifetime average is 23.3 MPG.

I'll frequently get 25 MPG on a tank, and higher than that on highway driving.

This is mixed driving, most of it suburban.

shurik74

I have the same numbers 19-20mpg last 10K miles but I don't really care, if I want comfort and power, you gotta pay for it ;-)

TeamAcura

Stop and go traffic...some highway and I average about 19-20 MPG like others. I'll fill up at the beginning of the week and have over half a tank left at the end of the week though.

SFarrow11

I just changed from the OEM tires which were netting me about 22mph to Continental ExtremeContact DWS and now I avg 24 mpg. I drive about a 30/70 mix of city/highway. Which tires are you riding on?

Well I've been driving like a grandpa this past week in an attempt to see how my MPG's reacted. My trip B has close to 4,000 miles and is stuck at 19.9. The trip A from the past week is at 23.2. That's with keeping it at 70 mph or less on the freeway and shifting before 2,500 RPM. I've also driven about 225 miles and about 90% of that is highway.

While it's nice to see an increase in MPG, this will not last much longer. I don't normally drive my car like a maniac but I sure as hell drive (i.e. accelerate) faster than I have been. Since it's Friday afternoon I'll probably return to my old ways but at least I have an idea of the best I can get.

I'm thinking I may try to do this one week a month. It will conserve some gas and make that next week much more entertaining.

I have a 12-6MT and have averaged 22.4 for the last 6000 miles - I drive 100 miles a day and 65% is freeway at 75 - 85 in the morning, and then stop and go at night. As for driving style, I'm seldomly passed. I accelerate faster than I should. However, once I reach cruising speed I milk the MPG.. Unless there is someone who wants to play. Than its all out..

Ant$

I'm only getting combined 19MPG on my 2010 SHAWD 6MT

and I do mostly highway driving. I can get really good highway mileage if I use the cruise control but since 2010s don't have adaptive cruise, it gets incredibly frustrating to use...
