Best I've gotten on my 10 TSX Tech is 37.x on a long trip from VA to Memphis. I didn't take a picture because I found that sudden arm movements affected the precision weight distribution that I calculated and thus the mileage. You'll just have to trust me.

I managed 32.23 on a trip to and from Northern Virginia from Virginia Beach this weekend. Gas light popped on at 508 and the car claimed I could drive 44 miles further and claimed I'd achieved 33mpg. I use premium fuel from WaWa on every fillup. Oil life is at 20%...
2010 V6 with tech @ 12,200 miles on the clock.

On a ride from Johnson City, Tn to Charleston, SC via Greensboro, NC... Could have gotten better but the first 100 miles where through the mountains.
I have gone to using "ethanol free" fuel and have changed to a K&N filter (looks like it has helped)

how do you guys do this !
I use 93 octane from BP NYC
I filled up. Driven 50 miles, 45 of them HW, & Im averaging 21MPG. 90% of my freeway driving I keep my indicator between the 25-40 mpg !
Should I switch to Say 91 or 93 Sunoco ?

I use 93 from BP as well, here in Va we don't have 91. There is a huge difference in the TSX city mpg and highway. It's a heavy car so if you constantly have to accelerate from light to light or stay in high RPMs it will net you closer to low 20s.
However the key to highway cruising is to let that K24 basically idle along at 2,000ish RPM at 60 (automatic tranny), you should easily beat the EPA rating and get low to mid 30s for your MPG. The engine is very efficient once at speed, it's the weight of the car and relatively low torque that kill city mpg.
If your really getting 21 mpg with mostly highway driving I would say check air filter/tire pressure but drive easily and keep your speed below 75.

I filled up, Currently have ~75 miles on Trip A , Avg 21.5 MPG && 90% is HW.
I'm beginning to get frustrated. My Mpg indicator mostly reads between 25-35.
Only exception is when I'm in occasional light traffic and HW ramps.
When I first took the car home out the dealership on the short trip home I got 28Mpg HW. for about a 10 mile trip. Now it seems impossible to get that High. && I think it's the gas, I'm driving the same. Coast on small downhills on HW the. get back on it steady, I have the technique it's just not gettin my MPG up. Next full up will be with 93 Sunoco && Then 91.
I'm goig to have to try different things. Back and forth 2 both of my jobs is all HW. I'm only on streets to get fromthe HW RAMP to my house

Thanks for the response, My car has 800 Miles, Shouldn't be a air filter not TP, All 4 are the same minus 1 that's off by 1 Psi. What should they be at? so I can inflate to where you all are.

Does anyone know What fuel is used to fill up at a dealership. When I get a chance I want to call my dealership. Can anyone tell me what their tire pressure is all around when they jump in their car. My fronts seem a little low. I want to say they're at 32 or something close to.
I got the i4 for the Gas mileage. at 21mph HW isn't working for me. Especially when my Meter is reading 25-35 on the highway

Using the car's computer to calculate mileage is not accurate, nor will readings at such an early stage give you a valid measurement.
Track fill-ups on a spreadsheet and calculate from there. The mileage on most cars improves up to the 8-10k mile range at which point it starts to level off.

wow, that is pretty low...
I drive 50% city/50% highway (with pretty bad traffic here in honolulu) and I'm averaging between 24-25mpg... and I thought that was bad.
my tires were a bit low when I was averaging the 24-25 (roughly 28psi). I just filled them back up to 34psi, I've been getting between 26-27mpg (although traffic has been considerably lighter in the past couple weeks).
coming from my tacoma, which averaged 16-17mpg, this is a huge improvement for me (cept going from 87 to 91)...
I only have about 3500miles on my car (11' tech wagon)...

I'm waiting for mine to get better with some more breaking in. I took a 2hr drive on Monday in the wet (water on road but hardly ever using wipers) and got 25.4mpg showing. With dry roads when I returned that afternoon, I raised the entire trip average up to 27.5, roughly 5mpg better in dry. It amazed me that pushing even the little bit of water to the sides made that much of a difference.

Yea im guessing its blc im still at an early stage, im hoping as the motor breaks in more my MPG increases,
3 of my tires were 32psi, 1 was 31psi, I went through another thread about people wl tires and different PSI for driving conditions. I decided to go with 36PSI front 33PSI rear. Car feels different for the slight psi difference, I can definitely feel bumps a little more, but i can also feel the car moving a little easier with less resistance.
TOday i may bring it down 34 front 32 rear

Intermediate
2011 Wagon running 93 octane, 33 PSI
3,000 miles on it so far. Lifetime average to date is 27 mpg.
First few tanks were 26 mpg, last 2 tanks have been 28.1 mpg.
Best full tank mileage was 33 mpg, best partial tank was 38 mpg (55mph cruise on backroad).

Amazingly Good
Finally took a long distance trip in the TSX, Pittsburgh to Kansas City and back. This is how we did on the main run back, filled up in Illinois and this is after arriving home in Pittsburgh.
We had a trunk full, 2 adults and 2 full sized teens.
I think pretty good for a car this size.

36.9 is a pretty impressive number considering your # of passengers. What year TSX do you have? Auto I'm assuming?
The most amazing thing about this TSX is the range in mpg you can expect depending on your commute.
-All highway at moderate speeds: 33-36mpg
-All city, stop and go with heavy throttle: 20-23mpg
That's a spread of 13-16mpg, the K24 shines at constant highway speeds
In my daily driver GMC Seirra 1500 with the 5.3 I get about 16mpg regardless of how I drive. Worst tank was about 15, best was 18.

I agree, the 2.4 is a great engine. Think what direct injection could do for it.
Mine is a 2010 Auto Tech and I think 36.9 is great mileage.
My lifetime average (now over 30k miles) is nearly 30 mpg in this car. Sure, most of my commute is highway but still outstanding.

This car gets great mileage when you keep your foot out of it. When you are trying to accelerate this 2 ton beast, it's going to take fuel. That's why the city mileage and highway are so far apart and is typical of most cars today.
A lead foot just makes the problem worse. Brake use and more fuel.
I used to have a Jetta TDI (Diesel) and really worked on managing the lead foot. If you find yourself using your brakes at anywhere other than a stop you have an opportunity to improve fuel economy. Don't get me wrong, I'm no slowpoke but it's all about conservation of energy (momentum in this case).

^ Good point. I do the 2K to 3K rpm starts, and when I see a redlight coming up, I usually come off the gas way before the stop and coast abit before breaking slowly.
Of course if it's in the redlight district, all of the reverse is true... rabbit starts and stops to avoid getting caught.
There is a bunch of Bible thumpers taking pics with phone cams and sending them to your spouse. If fact one local place will give you a piece of cardboard to cover your tag and they have a bouncer outside to make sure the thumpers don't mess with the Jon's cars.

neutral, really? look again, it's clearly in drive.
in all seriousness though, i just picked up my '12, hoping it matches or even beats my '06 tsx a little bit, so far, it's too soon to say since i've been spending a bit of time with it idling while programming the navi and learning the new electronics.
i always used 93 octane at the pump for my '06, is that what most people are using for the new generations, and do you notice a performance/efficiency difference if you switch between 87/89/93?
thanks.

From GM TSB #05-00-89-072B
"• Use the Recommended Grade (Octane) Fuel
Purchasing higher than required octane fuel is a waste of money. Using higher octane fuels in a vehicle that only required regular unleaded fuel will neither increase performance nor improve gas mileage. In all cases refer to your owners manual and ONLY use the octane rated fuel recommended for your vehicle."
From Car and Driver
"We ran all vehicles on both grades of fuel, at a drag strip near our offices and on a Mustang eddy-current dynamometer that was offered to us by the engine-tuning pros at Automotive Performance Engineering in nearby Clinton Township, Michigan. On arrival, all fuel tanks were drained and filled with 87-octane Mobil regular fuel and driven for two days before track and dyno testing. The tanks were drained again and filled with 91-octane Mobil premium and again driven for two days to allow time for the engine controllers to acclimate to the fuel type and tested again. All dyno and track results were weather-corrected.
Our low-tech Ram managed to eke out a few extra dyno ponies on premium fuel, but at the track its performance was virtually identical. The Mustang's knock sensors and EEC-V computer found 2 hp more on the dyno and shaved a more impressive 0.3 second off its quarter-mile time at the track. The Accord took a tiny step backward in power (minus 2.6 percent) and performance (minus 1.5 percent) on premium fuel, a phenomenon for which none of the experts we consulted could offer an explanation except to posit that the results may fall within normal test-to-test variability. This, of course, may also be the case for the gains of similar magnitude realized by the Ram and Mustang.
...Our tests confirm that for most cars there is no compelling reason to buy more expensive fuel than the factory recommends, as any performance gain realized will surely be far less than the percentage hike in price. Cheapskates burning regular in cars designed to run on premium fuel can expect to trim performance by about the same percent they save at the pump. If the car is sufficiently new and sophisticated, it may not suffer any ill effects, but all such skinflints should be ready to switch back to premium at the first sign of knock or other drivability woes. And finally, if a car calibrated for regular fuel begins to knock on anything less than premium or midgrade, owners should invest in a tuneup, emissions-control-system repair, or detergent additives to solve, rather than bandage, the root problem. Class dismissed."
I've seen the C&D test repeated by another magazine (I can't find the link) and they had the same odd results with their Accord. For some odd reason, Honda engines seem to perform worse when fed with gas that has an octane higher than the factory recommends - in our case you should use 91. Since our cars (at least the 2012's) run fine on 87/89, I generally get a tank of 93/92, then tank up with 89 when I'm about half empty, keeping the octane in the 91 range.
Do I save millions of dollars? Probably not, but I save enough every couple of fillups to pay for that big gulp - and that fills me up
