within the past month, it seems my mpg has done nothing but go down. wen i was takin the highway to work everyday i think i had the mpg up near like 28mpg,, but now its like at 23.9mpg, and idk if its maybe cuz of the way i drive or maybe MAF sensor i questioned. i have CAI. i do drive like crazy around the city, but would it really cause my gas mileage to drop and still keep goin down...

do you go off the computer gas mileage, or do you calculate it yourself?

bboyfreeflow

just from the computer

D4u2s0t

do you reset the computer every now and then?

and yes, driving like a maniac will get you **** mpg.

bboyfreeflow

i usually just drive it so u can hear the CAI HAHA cuz it sounds nice ... but no i dont even know how to reset the computer,,,,,, ...

you hit the reset button that is right behind the steering wheel. Just behind where your right hand rests on the steering wheel. I'm guess you are flooring it and losing a little. You also need to reset that bitch after you fill up to notice a difference.

i get 24city, 27 hghway, i cant figure it out though, i used to get 30+city 36 hghway, now it all went to ****, i blame all my bolt ons, lol...i dont drive fast either the highest i ever shift is at 25k...i tried to figure out where my fuel efficiency was going, i changed spark plugs, change fuel filter, changed oil, cleaned fuel system with some lucas, ran some seafoam, still getting shitty mileage, so in the end the nly thing diffrent was the bolt ons, lol

go in your dic control next to the steering wheel on the dash and scroll through the specs till you see mpg, then hold in the button on the right that looks like a return key on a keyboard. same thing as resetting the trip mileage calculator

07GatorSS

^ yeah reset the thing to get a more accurate reading of what your current mpg is after fillin up

blazinb

ahh dylydo beat me

bboyfreeflow

ohh i thought that button only reset your A Trip and B Trips anddd ****, cuz i know it doesnt reset your oil life, i had to hit the gas 3 times to reset the oil after gettin it changed,, ,but i will do that then

D4u2s0t

bolt ons will INCREASE your mileage as long as you drive the same. many people get worse mileage because they use the gas more after putting them on. but in the same exact driving situation, you will get better gas mileage with the bolt ons.

yea, try to reset it every now and then. and it's helpful for messing around with in different situations to see what gets what kind of milege. cruise on the highway, reset it. then reset it and floor the car. then drive normal and reset it. gives you a good idea of what does what, what helps, and what hurts.

though it's not 100% spot on perfect, i've found it to be close enough.

arkkornkid

did you check your gap? ....that'll totally cut your mpg's if you missed that step.

blazinb

It actually does reset the oil life, but you have to have the key in and turned on but not started, then go into dic and find oil life reset then hold both buttons in and it will say acknowledged

ScottxKillyou

also, what brand plugs did you put in in?

Actually it does reset oil, turn the car to run without turning it on. Then reset oil. Or press gas pedal 3 times while in run position.

stock plug are iridium, non gapable,as in they come gapped from factory, and they r the same GM put in the car from the factory, the 41-103's...and i know bolt ons add mpg, i actually know which of my mods is killing my mileage but i dont wanna say it

EvilleCobalt

It's a turbonator isn't it lol. Yeah I've noticed an increase in mpg after my mods to.

I had the same problem with mine. I was down to averaging 26 on city/highway combined and I took off the whole air intake system, cleaned all of it, cleaned the throttle body, put in a new air filter even though the old one wasn't dirty, and boom I'm back up to 32 on combined.

bboyfreeflow

i dont know, maybe my cold air intake is making me lose mpg.. haha. i did reset the computer tho, and i did notice wen u do step on the pedal, u **** up ur mpg

Sentry

I bet you messed up your maf sensor. They're pretty sensitive.

Replace that and I bet you'll be ok.

elbeno600

woah. before you send this guy off to spend money he may not have to spend i sugguest getting off the pedal a little bit. see if because its summer you may be just pushing it to much. use cruise on the highway etc.
