cwhsu

this is how it was achieved.
BONE STOCK auto tsx 08

Shell gasoline premium 93 octane ( im in VA so we have that here i think some states like cali don't)

non synthetic oil just regular i bought the car used so its whatever honda dealership had put in. i am about 70% oil life on the dash thing
(** i will be going full synthetic mobile 1 like on my WRX previously very soon when it hits 50% oil life)

NO aftermarket air filter (k&n) or CAI*** stock box with paper filter purolator from advance auto

air pressures at cold are 34front 32 rear
DURING driving, tires psi was roughly 40 front 37 rear

no A/C or heat
no windows down
Radio was On XM sat whole time

OFF all lights were off

ON Cruise Control was on

Outside temp was high 50's to mid 60's

avg anywhere from high 60's to 75 mph whole time~

I am very VERY PLEASED

so anyone else do any better MPG or have gotten better?



advice, opinions, comments, ideasssssss appreciated





AND FINALLY!!

Your fuel average isn't as high as the display says it is. Check it when you fill up. If your car is as accurate as mine is, you averaged around 38.8 for that second pic. I'd also be interested in knowing what roads you were on. If you were going downhill, then those numbers aren't impressive at all. If you were going uphill, they're pretty darn good. The wind also has a pretty large affect on your MPG. I've averaged up to 20% better mileage just because of a change in the wind direction before.

rt 66 and interstate 81 lots of up and downs mountain roads in fact all mountains~ all in virginia~

this was coming back from a trip Virginia Tech to Northern Virginia if anyone on this forums knows that area of western virginia they can vouch for the mountainous roads. and even so 38.8 is still freaking awesome

Itchytoe

I certainly can't argue that you got great mileage. Wish I could do that down here in Louisiana. Flattest roads around so mileage is pretty consistant for most days. You also have to have the AC compressor on all the time. Stinks for mileage, but I average about 32ish on the interstate during the summer. Down to 29 with stinky winter fuel.

valeratj

I live in CA and the highest fuel octane we get is 91. nevertheless I hit 36-37 MPG wth my car. I need to try it with octane booster and higher pressure in the tires

808havok_tsx

what are ya'll talking about? the best i've ever managed in mixed driving is 22.3 MPG. so much for fuel economy!

honolulu driving FTL!

gasser

can't wait till my 04 TSX finnaly arrives from the US =) that's a really good MPG!!!

LuvMyTSX

I didn't do better than 40, but I got 35 mpg in Jan 2008. No cruise control, had the heat on, snow tires on, completely stock '04 TSX. The drive was from NJ to DC, with some traffic on Rt. 95 and about 25 minutes of driving in the city. Pretty damn good if you ask me. Not going above 75 mph and avoiding slowing down and speeding up as much as possible really helps your mileage, so that's what I did the entire way. If it hadn't been for that half hour or so of driving in the city, my mpg would likely have been even higher.

And yes, make sure you do the calculation by hand, as the computer is always a little bit off.

kanonen

Cruise Control Off should give better results. Unless you have a flat uniform road without traffic.

nj2pa2nc

Yes we have achieved the 40+MPG but we used cruise control, tire pressure at 32 and regular gas.

Ken1997TL

In the loaner TSX's I've driven, my highway average was 36 to 38 mpg. This is with Oregon's crappy 10% ethanol.

2K6TSX

I wonder how much 40MPG is when compared with L/100km

litesout

40.1 MPG should be 5.87 L/100km. And no, I didn't do the math by hand. I googled a converter. FTW!!!

And to the OP, that's some pretty great mileage! I couldn't even get that going from SC back to Florida. All interstate, and it was pretty cool out, so I wasn't using the climate control. I did have the sunroof open for about half the trip though. It was just so nice out, I couldn't help it. I did make it from Columbia to Orlando without stopping for gas though.

psteng19

You actually probably did 37-38 mpg although the readout shows 40.1, but good job nonetheless.
Let us know what you got on the full tank.

I've gotten as high as 38 mpg on the MID on a full tank and did the math and it came out to ~36 mpg.

2K6TSX

my MID is at around 9L/100km and I'm happy enough with that, I get close to 600km/tank with my normal driving

xenonhid

Acura TSX FTW!

malnik

You can offend people when you call your TSX a bone stock car. =)

Ken1997TL

Oh I should add that my MPG were based upon what the pump said and NOT the MID

visuelz

I don't know how you guys can get such good mileage. Just recently I started driving like a normal person and I'm only getting 23 mpg and it's mostly highway driving. There's no way in hell I can get to mid 30s. My max was 31 but that was 2 years ago.

cwhsu

HAHA MY APOLOGIES FOR OFFENDING ANYONE SAYING BONE STOCK CAR

sorry~

XCNova

Just thought you guys would like to know that Shell Premium gas does NOT contain Ethanol. Only their Regular product does. Same with the Mid Grade, no ethanol. I have picked up considerably better gas mileage with Shell products instead of cheap gas.

litesout

Okay, that explains it. I gotta find a shell station. Unfortunately, they're few and far between around here any more. I noticed a big difference in my last car between brands that used E10 and brands that didn't. I just took it for granted that everybody was using E10 anymore.

LuvMyTSX

I thought everyone was putting in E10 also. I didn't realize Shell wasn't. Good, that's what I've been using for a couple years now. Shell also has a new thing with nitrogen in the gas. Not sure it really does anything, it's probably more marketing than anything.

LukeaTron

Nice. My best ('04 6mt, calculated by the pump as I don't even have the MID option) was 37.something from Pittsburgh to the Outer Banks last year (and through the same mountainous terrain you were in). Probably would have been better were it not for DC and it's craptastic traffic.

The TSX is no slouch in the fuel economy department. You just need to be reasonable with the gas pedal. This was much easier on the way to my vacation (nice and relaxed, in no real rush) than on the way back (god dammit, I have to go work tomorrow, get the shit out of my way!!!!).

visuelz

I find that shell gives me less mileage than mobil. It's also 6 cents more expensive for shell than mobil, where I live.

JB08

On average I'm getting about 9.2L/100, but that's mostly city driving (80%). That's not bad at all for a lot of stop and go.

odannyboi

I didn't resize it properly, oh well... I got it up to 44.3... but had to do a few miles of city

TSX408

good workin..

davidspalding

Due to the known fault with Honda odometers of that time, you actually got about 37MPG ... there's about a 10% error with the ODO resulting in slightly higher MPG estimates from the ECU. I've charted this for over a year, and could graph a flat line of the error rate from the MID to actual fuel-up calc'ed MPG.

Still ... 37 is about what my gf's Toyo Echo is getting in 70% city driving. Don't hesitate to go outside and do a "happy dance."

EDIT: Oh ... today's the 1 yr anniversary of my tracking my mileage.

miked8887

Is 133 miles the number of miles that the average fuel consumption was based on? If so, I don't think 133 miles in enough of a sample size for that average to have converged to its real parameter.

Just a thought.

davidspalding

Haha, Danny, I've gotten 39MPG or 40MPG just going down the freeway for 30 miles. Easy, just drive at 60MPH, and don't use gas on the uphills.

My fill-ups are usually at about 250 - 350 miles. I just filled up at 391 miles, though.

The variation in MPG between the MID and actual gallons per miles driven is from 5% to 20%. I have to spend more time in Excel to compare the size of the fill-up with the variance. Might correlate, might not.

davidspalding

Don't know about EPA, but Consumer Reports reports their own test review mileage: city, highway, overall, and 150 mile road trip. I generally think that a measurement where 5 gallons or more are consumed is roughly reliable. A 1 gallon trip, noooooo. A full tank (representing several days use, or combined daily weekday and typical weekend), best.

Varia

I don't trust the MID at all...which is why I do my MPG by hand!

I went from San Diego to Vegas the other day and got nearly 600 miles to the tank. 600/15=40. Nearly 40 real miles per gallon is...amazing! Not to mention that's with I/H/E and reflash.

1Louder

My mid averages just under 2 mpg off over about 24 months of monitoring, so the tank is best. My tops was around 37 mpg (actual) Seattle to Portland (once I got on the highway). On the highway, I think the TSX is one of the best if not the best when you balance out the combination of MPG, comfort, ride, and the speed you can travel (I averaged 70 on the run above). You have to get an econo-box or small hybrid to do better (except maybe a Camary Hybrid, but it's close).

ck123

was driving from vancouver to sf, i got 34 mpg going around 70-85 while drivng through the california/oregon mountains. AC was on too.
avatar picture is when i took that trip. that is mt.shasta

maclion

Good job, but 41mpg can't take hybrid. If i want, I can reach 65+mpg with my prius round trip between laramie, WY and Boulder, CO. Windy and Lots mountains there.

1Louder

I drove a Civic Hybrid for 4 years, and I've been in a Prius. Yes, those two can out-do a TSX in mileage, but they're not comparable cars in terms of comfort and luxury. I know the Prius > Civic when it comes to that, but I got to the point where I couldn't spend 2 hrs a day in a Civic any more. I can spend all day in my TSX and be happy.

CarbonGray Earl

And to add- the TSX gives you a bit more choice. You can get stellar get gas mileage on 1 tank, and decide to drive like a bat outta hell on the next.

With the economy hybrids, you're stuck with only 1 personality.

nj2pa2nc

I agree-the tsx is a very comfortable riding car with excellent MPG on road-trips. I personally think the Prius is ugly but that is my opinion.

gasser

As far as I understand for better MPG the car should be kept in low RPM. The problem is that I've just got the car and don't know much about it and I want to ask if it is normal to drive a TSX on a fifth gear at 40mph? The RPM at this speed and gear is slightly above 2000. This rpm was kinda fine with my previous car (1.6 Opel Astra).
