2.5L Fuel economy thread.--UNOFFICIAL--

[thygreyt]

Sh!t man you drive a lot!

if i drove less, then i would have more money to spend on the car!

but if drove less, i prolly wouldnt have the motivation or desired to mod so much.

all i do and all i have done, is to try and improve my driving experience.

[GTACanuck]

Filled up with some Shell 91 today. Last tank was under 23mpg on some sh!tty gas station that I usually avoid like the plague. Paid $5.60/gallon

Tank is not looking so good with 91.. Im not driving her remotely hard and I have only got 170km to my first 1/4 tank.

Weird, I got 26.4mpg on this tank with 50/50 driving. Thats my second best recorded mpg. Filled back up with regular today to see if i can match it.

fuel?

[GTACanuck]

fuel?

26.4 on 91

Fulled up on 87 today. My best recorded was done on Shell 87

[magics5rip]

Last tank was 322 miles on 13.0 gallons. Still hovering in the mid 25's for my regular commute. If I stayed off the accelerator a bit more, economy would improve but that isn't happening any time soon

try shell 93 if its available to you.

[GTACanuck]

try shell 93 if its available to you.

We can get 94 here and not 93.

Shell Offers: 87,89,91
Sunoco / Petro Canada Offers: The above plus a 94 Octane

I will try the 94 on the next fill and report back. Gonna take it in the hoop though for the price, hope its worth it.

you better try a couple of tanks... 1 wont show much...

[GTACanuck]

Got 20.8mpg on my last tank. But I do have an excuse as to why. I had a passenger in the car for a good portion of the night while parked.... Felt like I was in highschool all over again

[magics5rip]

About 360 miles from 12.85 gallons of gas ~ 28 MPG. City driving was mabe 20% of the total tank.

[thygreyt]

i am getting 28 ish consistent... regardless of doing city or hwy.

thats cuz on the city i neutral cruise, a lot.

[Zoolook_]

I don't know why I can't embed this image in the post...

[thygreyt]

ok so, another weekend, another roadtrip.
a total of ~800 miles traveled.

tank one yielded 378 miles and tank 2 gave me 390 miles...

both had a total of 28 ish MPGs.

funny, on unitronic i always did 25-28 mpgs... for 28 i had to try a little bit.
now, on United Motorsports +SRI i am doing 28 consistently with no real effort!

the mani should have damaged the economy... i happy it didnt with the right software!

[Zaytri]

I have no idea how you guys do it..

I'm pulling 18-19 MPG City, 25-26 MPG Hwy when trying hard to get MPGs - Usually end up with 22-23 mixed. I almost always get sub 300 miles on a tank, sometimes i can squeak out 305-310.
Only Shell/Top Tier go in the tank (unless stranded with no other choice)

Maybe my foot is just too heavy.. I do enjoy myself

i ONLY use shell... chevron when not a shell nearby.

one key thing for better economy: learn to drive in neutral

I think I posted this in another 2.5 Fuel thread, but the injectors go into fuel cut on de-acceleration above a certain RPM correct? So wouldn't neutral coasting have a minimal effect?

[thygreyt]

yes, you did mentioned it.

the thing is that neutral coasting means iddle RPM and less drag from the drivetrain, since no gear is selected.

[jaja123]

is it normal to have fuel economy drop after installing the usp midpipe. I have the high flow cat version. I think I am getting less miles on each tank.

[GTACanuck]

Looking good by this. Gonna be filling up tonight to see how I actually did.

[HollisJoy]

I think my car is lying to me

[thygreyt]

lol, it looks like it!

i discovered that if i were to travel between 40 and 50 i can get +30 mpgs!

[thygreyt]

lately i have been reving to 4k and some mixed driving (city/hwy) and still getting 28 mpgs...!

i love it.

i fueled up 13.7gallons

[nickbeezy]

i consistently get around 28 mpg mixed city and highway.
on my road trip to NYC next weekend i plan on making it there on one tank of gas, no filling up allowed!
last time i just about made it to my destination as i drove on the gas light for about 20 miles

if i can get about 32 mpg driving around 70mph i will be happy

[magics5rip]

332 miles from 13.3 gallons. Hoving around my typical 25 MPG. But, I do see a fair bit of stop and go and there are certainly daily pulls past the 5k rpm point. I'm not driving like a granny for 28 mpg

lol... i do enjoy the car...

if i drove like a grannie i'd easily break 30s

I need to do a full tank of highway to get an indication of how the UM software + intake have effected it. On a short test, I calculated 32mpg which is easily better than the car was performing stock.

[thygreyt]

the stock 2.5L is soooo unimpressive.

anything modded to it, and it starts becoming something else entirely.

[magics5rip]

I almost sold my car because of it! The last ditch effort to make the car fun was the simple mods; now I don't want to get rid of the car.

it seriously sucks, all round.

then you chip it, intake.. and it suddenly becomes entertaining... almost inspiring. Aspiring for more.

then you put an exhaust: you create music.

The burble on the deaccel is one of my favorite parts of the new tune!

yes, UM's tune leans out on decel (16s and 17s) which makes a nice gargle.

i love it.

on my car this is VERY pronounced... and fun.

Mine isn't as pronounced since its a stock GTI res with a 6" round x 18" magnaflow up front and no suitcase. Not loud, but a nice enough sound for me to notice. I also need to build a microphone power source for the HD cam so I can use a condenser mic and record a decent representation of the sound.

[DerekH]

Yeah, mine snorts a lot on the decel too. It's a really satisfying noise.

Mine does the same on the C2 tune... And it sounds awesome! Granted, the test pipe really helps! lol It pops on some shift too

[DUSlider]

I actually feel that I get better mileage going 65-70, then keeping it around 60. It almost seems that the momentum helps keep the car going to overcome wind resistance, thus requiring less power from the engine. Or the engine is more efficient and has more power at the rpms at that speed in that it uses less gas.

I have C2 93 programming, BSH intake and Eurojet Exhaust and the heaviest MK5 (4dr auto w/sunroof) short of the R32. Will keep track closely of my mileage going down to SoWo.

Lifetime mileage is 24.5mpg combined. Best highway tank was 37mpg.
