I get a very consistent 23-25 MPG on a daily basis (most driving in and around town), and get a consistent 30-34 MPG when driving the majority of the time (95%) on the highway. I think it's your driving style. Try not to bounce it off the rev limiter every time you shift, and your numbers should improve.

Another mileage update.
327 miles on 10.189 gallons of 91 Octane
That is 32 mpg, which is up slightly from 30-31 I have gotten previously. That tank was 30% suburban and 70% expressway.
Plan to change to Mobil One 0w30 at next oil change.

Chitown-TSX

Daily commute 94 miles a day, 40%city/60% hwy, average 25mpg.

My last all highway trip, no A/C, windows up, average 33.5 mpg.

jcg878

I'd jump in to a least gals per month contest. My average commute has 8 miles of driving. My fuel economy is terrible in terms of MPG, but pretty good for GPM. I actually miss driving my car more, but it's not worth sitting in NJ traffic when i can read on the train. Man am I getting old quickly.

I can't imagine 94 miles per day, that is crazy! Are Chicago commutes generally that bad?

Chitown-TSX

I live in the southern suburbs and work in the northern suburbs.

For those who know the area, I live in Orland Park and work in Northbrook. I live 2.5 hours a week-day on the Tri-state tollway.

Count Blah

Yeah, I meant least gallons/month. :P That's what this whole gas mileage thing is about, right? Conserving our resources and saving the environment? I've probably used just 80 gallons in three months.

sauceman

Then I guess I'm out.

LeMasseHammer

Well, I went a whole tank with moderate driving, shifting at 3k RPM mainly. I did hit v-tec twice -- couldn't help it
I ended up getting 23MPG. This is with the A/C on about half the time, and for this tank I did about 95% of my driving in city. I plan to go back to the lead foot lifestyle for sure. Saving 1-2MPG isn't worth it to me.

And I'm very satisfied with 21-22MPG in the city.

UTmtnbiker

Well, after a month and a half, 1600 miles, and 3 tanks of gas, I'm very, VERY pleased with my milage results.

Of course, my method isn't the most scientific one, but I'd say it's +/- 5% as I don't top off my tank when I fill up. It's the old, drive till you fill up, record how many miles on your trip computer, divide that by gallons put in to the car.

However, on 3 tanks so far, I'm averaging 28.2, 31.6, and 31.9 miles after the 1st, 2nd, and 3rd fill up respectively. I'm getting oiver 400+ miles on one tank.

I'd say I'm about 90% to 95% freeway driving along with not being a lead foot. I've probably spooled the engine above 3k RPM maybe 10 times since I've owned the car. Very happy with the results so far. Had an old 1990 Toyota Corolla with 108hp and I was getting around 35 mpg and believe me, the TSX is MUCH more fun to drive.

inkytawney

I assume you are posting 6 speed mileage.
I have gotten similiar results and I am very pleased.
My 95 Accord LX 4 5 speed got 27-28 at most.
My 95 Max Se 5 speed got 27 at most
My 92 civic 5 speed got 41 at most.
So my 30-32 is very good for this level of performance.
The low cd of .27 is helpful.

UTmtnbiker

Actually, it's a 5AT, not the 6MT.

inkytawney

That is good economy. I am babying my TSX this tank full but still redlining on the onramps. I have managed to be a 263 miles at exactly one half tank. My previous tanks were 237, 240 and 230 on half a tank and they yielded 30-32 mpg.
Overall I like the economy and performance of this car.
first oil change I will add 0w20 for the winter and go to 0w30 for next summer. Mobil One of course.

Roadrunner_RENAMED

Average 29 with 6 mt 70/30 rural/city.

mrdoug

jsx, your post on 10-1 said, in part: "My fuel economy is terrible in terms of MPG, but pretty good for GPM." What the heck do you mean by that???? Can anyone else tell me? What am I missing, or is he/she??? Thanks.

Count Blah

GPM = Gallons per month. We were talking overall fuel usage.

mrdoug

Well, I knew what GPM meant, but bad MPG cannot coexist with good GPM; it's a contradiction and mutually exclusive, unless by "good GPM" one simply means that one doesn't drive much and, for that reason alone, doesn't use much fuel. Ok, I guess I get it now - he means he doesn't drive a lot and therefore doesn't use much gas. Thanks.

mrdoug

This is an interesting thread. I have a 6 MT with 2,400 miles, about a month old. I have not yet calculated my MPG, but I will now and will report back. It's interesting to read about everyone's driving styles. I guess I qualify as a relatively "conservative" driver, in that I rarely take the RPM's over 3,500/4,000 and usually keep them around 2,300-3200. This is probably a function of my relatively advanced (45) age and otherwise bourgeois lifestyle. You know, a wife, 2 kids, a dog, a 2000 Subaru Forester (for the wife 2 kids & dog), and a milano red 6 MT TSX w/o navi, w/spoiler).

Count Blah

Yep, I think I started that. I get around 20mpg consistently, but don't drive very much, so my total fuel usage is pretty low.

In that vein, it could be argued that someone who drives a Hummer just a mile or two a day is putting less strain on the environment than someone who drives a hybrid on a 100-mile commute.

Also, you could theoretically get GREAT gas milage by driving extra miles. Take the long way to work at 45mph with zero stop lights, coast around in circles without ever braking. Your mpg would be better, but you'd use more total gas.

boo2

Is there another way to calculate MPG besides taking the milage ending divided by the gallons put into the tank without "top off". Also someone mention they got better gas milage after a couple of fill ups. This will be my second fill up and I got less MPG than the first time I filled up. Thanks in advance.

Crazytree

still getting 19MPG... getting mad now.

ClutchPerformer

Are you sportshifting or no? Do you have a really heavy foot?

Crazytree

don't sportshift. define "heavy foot". in my head there is only one way to drive... ???

gogozy

short trips, frequent stop and hard accelerating will hurt "MPG"

idx

Are you flooring it everytime? (<== heavy foot)

inkytawney

Mileage update. I continue to average well into the 30's. todays fill up on my 6 speed 420 miles and had to jam in 12.4 gallons for grand total of 34 mpg. I cannot imagine what would be possible in this car with a proper 6th overdrive. Kind of a shame. Car now has 2200 miles

sauceman

Props for the good gas mileage.

If you wanted a good overdrive final gear, you should have gotten the 5AT. By definition the 6MT has a sporty "attitude", and the tranny must be geared accordingly.

ClutchPerformer

And that may be the issue here. Heavy foot = Hard acceleration all the time. There's no way you'll get good gas mileage and drive fast at the same time.

ClutchPerformer

I disagree.

Close ratio gears are great and sporty and I appreciate them, but there's no reason at all why 6th needs to be so close to 5th. That 5-6 closeness is useless unless you're racing someone at 120 or so. I don't think that'll happen too often.

This is still my biggest beef about this car. I guess I should be happy....

rb1

Well, there at two things you can do when adding additional gears.

1. Leave the other ratios alone and add tall top gear for cruising. Good for fuel economy. Bad for top gear acceleration. No improvement in overall performance.

2. Squeeze all the other ratios together with little or no change in overall top gearing. Bad for economy. Good for top gear acceleration. Good for overall performance since other ratios are closer.

In the TSX, they have taken approach #2. Even so, I've found its top gear performance to be somewhat anemic. I'd never consider passing someone on a two-lane road in a TSX without downshifting (something I routinely do now in my current car even though my gearing is actually taller than the TSX).

ClutchPerformer

Right. I'm saying I'd prefer something closer to #1. Who cares about top gear acceleration? I don't know why it's even measured. If I really need to accelerate, I'll be in 4th gear and be gone.

inkytawney

I was reading a piece yesterday about the new 330i special parkage garbage or something for arround 40k. Anyhow, article mentioned a "true 6th overdrive". That is what the TSX needs. I contend 5th could be made a little more highway friendly for those who want immediate grab ass power and reserve 6th for general cruising. BMW took this approach and from their 6 cylinder rear wheel drive car get awarded 30 mpg highway. I have found over many years and reading tests that BMW consistently gets excellent fuel economy from powerful and fast cars. On the comparision tests you always see excellent actual mpgs in the tests over other make of identical or lessor performance. Take the G35 for instance--a true gas hog compared to the competition.
I like the TSX but believe HOnda should rethink the top gear.

ClutchPerformer

Technically our 6th (0.659:1) is an overdrive too (i.e. output:input ratio of less than one). And by that definition, our 5th gear (0.821:1) is also an overdrive. The problem is they're still not tall enough overall at the wheels (which may be a final drive issue). I'm not sure what a 330i's final drive ratio is, but the TSX's is really short (numerically high) at 4.76:1.

At the wheels is where this stuff really counts. The BMW may now have a "true overdrive", but I wonder what RPM it's turning at 70 mph in its 6th gear. Anyone know?

rb1

Well, I guess this is a matter of taste. There are lots of other qualities that go along with this -- car feels peppy on the highway, handles grades with minimal throttle adjustment, can handle MUCH steeper grades without downshifting, exhibits less change in responsiveness when you have passengers.

My 88 Integra, incidentally, had the best top gear passing performance in its class (even with only 105 lb-ft ) and still got 34 mpg. It turned 3500 RPM @ 70 mph and 4000 RPM @ 80 mph and purred like a kitten the whole time. Even 4500 RPM @ 90 mph was sweet. I loved it...

ClutchPerformer

Definitely. I'm not saying it's not smooth at those RPMs. It's smooth all the way up to redline. I'd just like to turn less RPMs so I can get the gas mileage benefit. My dad and I rented a Toyota Corolla 4-spd auto that did 2500 @ 70. It's not that hard.

OldManTSX

I probably average about 29. The lowest I've seen it is 27.

mrdoug

Since originally reading this thread, I can now report my gas mileage on my 6 MT. Based on one tank, it was 28.45 mpg, which is a lot better than I was expecting. Btw, it was mixed highway (usually around 75 mph) and city, and I would consider myself a "moderate" driver on the aggressive vs. passive scale. In other words, I generally avoid jackrabbit starts, maxing out RPM's in each gear and the like, usually keeping RPM's between 2300 and 3500, although it isn't too unusual for me to rev to 4500-5000 rpm when I need to accelerate for a pass, for example. So, I suppose this result is pretty consistent with what Acura has projected for this vehicle, maybe even a bit better.

mrdoug

I forgot to mention that my car has 2,900 miles on it.

STC

iTrader: (1)

I average 25mpg

jcg878

Alright, just filled up after a weekend trip to the poconos (2 hr each way) and 3 days of commuting - 375 mi, 13.2 gallons, almost 29 mpg. I feel better.

It's funny how high gas mileage is a source of pride, when it really only reflects the amount of highway driving you do factored with how timid your driving style is (apologies to sauceman).

Iceman

I like the TSX's 6th gear just fine. I pass cars all the time in 6th gear on 2-lane highways. The advantage of the current 6th gear is, you are at 3000 RPM at 70 mph, which means you CAN accelerate. In metro highway driving I am constantly slowing down and speeding up at high speeds. It is more relaxing to be able to leave it in 6th and drive.
