I wanted to know how many miles you guys are getting on a full tank of gas. I know there are alot of factors to consider such as city or highway driving. I do a combination of both. In any case just having a few numbers put in I should be able to get a average of what is considered "normal". Currently im getting 240-260 miles on a full tank of gas.

 

Lately, it seems my car's fuel light comes on when there should still be 5 gallons left. ????

But I have driven over 400 miles on a tank before.

After seafoam, new tires, plugs, etc, I did a highway trip getting 33+ mpg.

 

I've been tracking my mileage on the iPhone since Jan '09 (I am a spirited driver):

Avg MPG = 25.74
Max MPG = 29.29
Min MPG = 21.75

 

270-330

 

Most I've gotten is 300 but that was to the 1/4 line. I try not to let it get below that.

 

Here is a link to a poll, showing most members use 91/93 octane.
https://acurazine.com/forums/2g-tl-1999-2003-98/what-octane-gas-do-you-run-773617/

I noted the car gets proportionally better mileage than the increased cost,
and 91/93 is all I've run since.

 

I used to get 250-270 changed my sparks I think I went to about 300-310 or something I don't remember, it was over 6 months ago.

 

Very rarely do i ever get less than 300 even when mixed and have gotten over 500 all hwy.

 

Oh and a quick use of the search button brought up at least 15 threads with the same question, all with the answers you are looking for.

 

i get 240-280 when the light comes in depending on how I drive. And that's with my transmissions problems.

I'll expect more when i rebuild the trans

 

the low light comes on at ~3 gallons remaining, with approx 2.5 to 2.7 of that able to be picked up and used (based on most I ever put in-tank stated capacity 17.3)

So its fine to run till the light plus another 30 miles, no sweat.. and have some left in the tank
the guage goes a few clicks below empty before it really is empty

IMO-anything under 300 miles mixed driving till the low fuel light-
is cause for a plug ck, seafoam, clean TB, ck air filter, tire pressures, and learn the fuel saving driving tips for in town

 

94 octane 10% ethanol 300 miles. shell 91 octane 0% ethanol 400 miles.

 

I actually am getting 410 Mi
but i pretty much only drive to school and back (60 roundtrip)
so its 90% highway

 

i think im getting well under 300 right now. im doing 80% city driving and im constantly hitting VTEC because im always late for class haha.

 

Avg: 26mpg
Min: 20mpg
Max: 31mpg

Highway full tank Will get me +480m..

 

My car was doing really good on gas until my tranny gave then i was doing 220 on full tank. I had my tranny rebuild this year and now im getting 250ish.

I've been doing some research and they say to retune your car. Is it safe to do that?

 

Dunno about the term RETUNE what that means? Resetting the ECU perhaps?

 

I want to join this also
I have the exact same driving for the past 4 years of 40 mile round trip for work with about 18 miles total on the highway.
always fill up at about 330 miles and average anywhere from 22 (winter gas) - 23.8mpg

 

that seems realistic. when i had my scangauge installed on the TL i was getting 33mpg highway when i was trying really hard, with pulse and glide, ride at highest ignition timing and 40 psi tires etc. But then i now i have the scangauge setup on another car, without it i have no guidance and so i get crappy 18 mpg combined. if you want good MPG this is a good device for it. it used to show me brake horsepower, instant mpg, rate of fuel burnt per hour, ignition timing, etc.

 

I drive a good mixture of highway/city, and I also do a lot of driving, but I normally do 260-280.

I do around 280+ when I drive around with the light on or at least really close to the light turning on. When I do 260-280 is when I'm like 2-3 clicks above E.

 

330 miles with the light just coming on - mixed city/highway. 400+ miles all highway.

I gained 30+ more miles by getting an alignment after, I believe, I installed my coilovers.

 

I've done all of that, but still need to do my second treatment of seafoam.

I get around 270ish though... But every gas station i've been to down here in New Orleans has Ethanol in it.... =( I wish I could find a station with no ethanol, then i'd probably get optimal MPG

I need to find that station!

 

280-320 depending on how much hwy driving I do.
Haven't done a full hwy trip to see how it does.

 

91 octane.. i've gotten 350 but avg is probably 330

 

99TL 91octane 28miles weekday (18highway + 10stop & go) 350-360miles

 

I just refilled from a costco that sells gas @ $3.75. which is really cheap in Detroit suburbs. And I got about 380. and i drive really conservative. I feel like im doing something wrong but I have seen the other threads and seems like im doing everything ok

 

Toronto, Canada

 

Canada....ugh

 

91 octane NO Ethanol, car has 140k on it. The light usually goes off at 310 miles, 75% highway mileage.

Also I just went back to that Costco and saw that they had an octane rating of 93! does that change things? am i running richer or leaner? are there changes i should do to optimize my efficiency?

 

Last 2 tanks: 312.7 & 319.6

 

could resetting ECU really help?

 

I get 280 miles most of the time.
450kms.

 

Resetting the ECU won't hurt in the long-term; give it a shot. It'll just relearn.

I've been tracking mileage on mu iPhone as well (very spirited driving):

Average MPG: 25.62
Maximum MPG: 30.12
Minimum MPG: 21.75

Most weeks I go 365+ miles before a fill-up near empty.

 

My TL-S with 156k use to get 230-240 before the gas light turns on. I also had idle problems, but after I changed out the IACV (or my mechanic called it the solenoid) I got 170.. Hopefully this tank of gas gets better. I drive mostly city with probably less than 50 miles highway..

 

Since I've gotten a speeding ticket, I've had a lighter foot.

I got 304 on my last tank, and that was cutting it close (Gas light on, and the needle touching E)

 

I got 450 miles out of this last tank. All highway and I brimmed it. But it was EMPTY. Well below E before I pulled off to fill up again. I was trying to avoid causing my wallet pain.

 

I do pretty much all city driving with a very heavy foot since im always in a rush to get to class or work and I get at least 250 miles out of a tank and average about 21-24mpg. When I take it out on the highway I know for sure I could get 400 or maybe even 450 miles out of it not riding on the light much.

 

I consistently get around 370 miles a tank on 91 octane. I average 23mpg and drive with a light foot, though it's pedal to the floor on on-ramps. My drive is 80% highway, and I run my tank down past E.
