MPG, what's yours? Options

[frosty]

I just got done testing my mpg thinking it might be crappy since I read the 5s-fe runs rich and plus with the car being 'round 12 years old, but I was joyfully surprised to see I'm running 29+mpg city. (with ac running sometimes and having a heavy foot)

Just something to make me love my car alittle more, since I expected 24-.

I'm curiouse though since I want to either add a turbo or swap to a 2nd gen 3sgte as to what my mpg would turn out to be.

Who on here with either a 5s-fte or a 3s-gte swap (or the very few who have a 5s-gte) checked your mpg?


Just really curious.

(even if you don't have one of these set-ups you can still post your mpg )

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.
