MPG, what's yours? Options

[cjh4l22]

i got 465ish miles to my last tank of gas. so... idk what that is, like 29.8?

[lagos]

city driving with lots of boosting at 15psi = 19mpg
city driving with lots of boosting and AC = 15mpg (owned)
highway driving = never really checked, but i would guess about 25mpg if i just cruise
Boost = priceless

wait...how many gallons is our tank??

if you try to divide by our tank size, then you wont get a correct mpg. you have to divide by how many gal it took it you fill it back up to full.

about 22mpg on my turbo'd 5's

'bout how much psi do you run? (also is it more city or highway, or a mix)

I'm thinking that when I go turbo with either motor set-up that I'm probably gonna have a low psi for daily-driving and up it when I'm feelin kinda frisky.

celi (stock 3sge) = 400k/tank (a/c w/lead foot) city
curren (stock 3sge) = 450k/tank (a/c, wife driving) city

i get aabout 20-21 in my 94 GT.. how do you guys get 30? What factors are involved with gas mileage (mechanics of the car etc) I mean is there something I could be doing to my car to get better mileage? I already have made a concious effort to not have a lead foot, not speed too much, but what else?


ahh i hate having low mileage

What kind of driving do you do? The more stops and starts you have to do the worse it get. Simple things too like tire pressure, how much extra weight you have in your car, ac running on high.... little things add up.

As far a weight on my car I have a cf hood which is MUCH lighter than the stock aluminum one, and my rims are lighter than the ones I had before. I try to keep junk out of my car too but that's also since I like a clean interior.

Motor wise, I just keep on top of fluid levels and make sure everything is running good. ( I also I started to add some fuel injector cleaner every other tank, under $1 if I remeber right) I use mobile 1 synthetic oil too.

These are the things I can think of that contribute to having good mpg.

i am just at 7.5 becasue its my daily driver, and yea, its a mix of highway and city, with lots of boosting

[BBW 99GT]

stock 5sfe 99 GT w/ manual trans (odo. 95,000 mi.) 30-34 MPG

drive 50-65 mi. a day, some highway, some backroads

use to get 30-32 MPG using 89 octane and a bottle of gumout injector cleaner or full fuel system cleaner from time to time / then I tried a different brand of full fuel system cleaner 1 time about 2 months ago and now I consistently get 33-34 MPG on 89 octane

[netrata]

31 mpg or 3 weeks on full tank of gas with spirited driving.

Let's try to get some more turbos on here...

What fuel system clear did you switch to?

I get 25 MPG half highway half stop and go, I try to keep it under 3k RPM's, but sometimes I find myself doing more spirited driving.

[fuent]

my mpg is **** and i have an intake too, its really pissing me off

[celicanice]

my buddy who sold me the celi said he got 400miles off of 87 and 500 off of 93 (1 tank)

[cjh4l22]

yea let me refine my post a bit. i had emptied the tank before, put in 15.2ish of 93octane + oil change(castrol synthetic) and fuel injector cleaner. = 465miles. pushing the car a bit, but mostly cruising to/from school.

things that affect gas milage. engine displacement, air flow, temperature, brake situation (seized calipers = bad), condition of fuel injectors and spark plugs, number of stop/go's, a/c, FI (turbo/super), tire sizes and weights, junk in car, junk on car, etc..

so.. want better gas milage?
displacement: a 1.6l(like netrata..)/1.8l is gonna get better than a 2.2l b/c the 2.2l needs more gas for the higher displacement, nothing u can really do to change that..
air flow: w/a cai/rai you should get better because there is more air flow through the engine and its less restricted.
temp: your car runs better when its cool outside. say between ... 40-70ish too cold and its brutal. too hott and its murder, sorry but u can't change the weather.
brakes: you should avoid riding your brakes and brake sooner when coming to a stop to possibly avoid completely stopping. even the slightest roll is better than a complete stop, so leave room to roll up behind the car in front of you.
fuel injectors: bad/old fuel injectors will kill gas milage, replace them as necessary or use fuel injector cleaner, it does wonders for higher mileage cars.
a/c: running air conditioning means taking engine power from your wheels and moving it to a compressor to keep you cool.. try putting the windows down or just running cool air.
FI: forced induction cars are gonna get worse gas mileage due to the fact that there is more air in the piston chamber and it requires more gas to fully ignite. so.. enjoy the boost lol
tires: skinnier tires = worse traction/performance but better gas mileage. less rubber on the road is easier to move. so if you have like 205tires move to 195.. oh and don't forget to check tire pressure.
wheels: lighter wheels will perform better than heavier wheels due to the fact that it takes less force to move them.
interior/exterior accessories: i've been told that for every 100lbs in/on your car you lose about 10hp, i'll look into it but if thats true then the body kit you bought that weights 50lbs more than stock, just wasted you 5hp. and the underbody lights, emergency equipment in the trunk, spare tire, subwoofers, etc.. are extra weight. get rid of these items or minimize them.

wow so thats a lot to digest but thats my general understanding of it all.. if anyone thinks i'm mistaken, plz lemme know. thanks.

[Kadett]

20 MPG (City Driving, lots of boosting)
30 MPG (Highway cruising @ 65-70mph)

I read in a mag. that the rule of thumb was for every 50 lbs = 1 hp.

(the mag had a civic which the guy re-did the whole body in CF and lost 500 lbs in doing so.

[NaderG]

My vert gets about 25 MPG when i use shell gas , about 50% city and 50% highway no faster than 70mph, if i use other cheaper gas , i get worse MPG

[K-ESD]

I get somewhere around 700kms (434miles) on a full tank IF I *try* not to push it. Which is hard, cause the weekend is playtime. Thats on 93 Shell gas.

I should dedicate a tank as an experiment to determine the top fuel mileage I can get with this thing. I'm sure I could break the 30mpg barrier if I don't push it once from full to empty.

(keep in mind what's in the sig)

[axelrduvirage]

9l/100km or around 26 mpg combined. SHELL V-Power fuel, 100% synthetic, clean K&N, 150 000 miles on the 5sfe (99GT)

[elvasoshexai]

no matter wat i do i get a consistent 21-22 mpg...
whether it's 100% driving in suburban stop and go traffic like a grannie
or 100%spirited driving in suburban stop and go traffic
or 99% highway @ 140km/h
or 99% highway @ 100km/h
