gas mileage

**Pontiac Racer** · 01-07-2015

i don't know if its me but i get ****! my dic says like 14. ill reset it'll say 21 about and then freeze at a crappy mpg. i get like 210 miles before it goes into the orange. yeah. the dic says I've only used like 13 - 14 gallons when i fill up. is this right?

**02NavyBlue** · 01-07-2015

13-14 is correct. When I fill up, in the yellow zone right above E I put in 15 gallons.

**danielle15** · 01-07-2015

Filled up today at managed 15 mpgs. Whoops.

I don't trust my DIC. My mods, highway at 75 MPH, and four adults, A/C on, it read 35 MPG!

My GTP SUCKS on gas

**SuperChargedPB** · 02-19-2015

How do you guys see how many MPG you are gettin. I have an 04 GTP

**SgtMarshal** · 02-19-2015

best way to find your gas mileage is to calculate how many miles you drove and then divide by how much fuel it took to drive that far.

**SuperChargedPB** · 02-19-2015

Cool.. Any suggestions on parts I should buy to make my GTP faster

For instance my last tank of fuel was 14.9 gallons to refill and I went 167.2 miles...11.22MPG...my car is REALLY hating the cold weather.

I used to use the "Fuel Log" app. Super handy. Has a lot of other features also.

Mines 2. My car is really a gas guzzler

**Emptydarkone** · 02-19-2015

I find I get better gas mileage if I keep the gas pedal about 2" above the carpet on the floorboard. I'm still getting less than 20 MPG in this weather due to warm up time.

I find that I get the best gas mileage by not driving my car. It's crazy.....

Lol

12.9 on my last fill up. E85, mostly in town. I usually let it warm up for a couple minutes before each trip. Oh, and my kids like to see the boost gauge max out. So that doesn't help either. LOL

**schlabby** · 03-03-2015

'03 SE, 185k... Went on a 2,400 mile road trip last summer, averaged 33mpg. Around town, more like 16-17; but I have a lead foot.

**aaronpaul** · 03-14-2015

I get between 16-22 city 25-32 on 91 octane in my 2004 gtp comp g. I have a light foot and usually only do about 65 on the highway..

**pames93** · 03-21-2015

26 all highway and I really tried my best. Usually 21 mpg as for full tank mileage I can't tell you because cars under the knife right now and I can't remember off hand

**02NavyBlue** · 03-22-2015

Got 13 mpg from 2/27 to 3/18, all city and short trips of course. 13 is ok, I'm down 2 mpg from this time last year though, which is odd. I was getting 15.1 this time last year. I have some intermittent starting issues too, I'm going to replace the upstream o2 sensor because it could help my mpg's. The original one is still in there now, it doesn't really look too good and the rear one already went bad, might as well do the important one. For $31 for an oem Ac Delco, you can't go wrong.
