Maybe a little heavy on the gas because it sounds so good???

I installed my V2 a few weeks ago and I'm getting about 26mpg highway and 22mpg city, and about 290 miles per tank

Blazing GT

be happy I full up every 3 days

OP sorry but do you know what AVG means LOL

how many miles did you go when you got 15 mpg ?

Bayam0n

lol, went like 10 miles since i installed the intake, hmmm, maybe i should wait until I reach 50 miles??? wow I FAIL.

01tl4tl

drive it 3 tanks and then you will have an average,,a few miles tells nothing
You guys and that MID crack me up

How old are the spark plugs
Done an intake manifold cleaning? fuel tank additive with good stuff?

well when i reset the trip at the gas station....i get like 15 mpg till i get to the highway (1-2 miles)....and then am on the highway going home for like 12 miles where i get about (30-32 mpg)....when i get home am usually averaging 26-28 mpg and i dont even have a V2 LOL !!!

wanna do an even trade between AEM CAI and v2 LOL ?

Spark plugs should be good for 100k. Your just liking the new sound too much and probably running it harder.I know I did.

01tl4tl

that instant readout is less than accurate over the long run
It does give an idea of how much throttle you are using~

Go by tankfull(s) and you have a real average

You can light throttle it from that gas station up to the freeway cruise speed and get high mpg numbers... till the car brain catches up with whats going on

i reset my trip meter every oil change (~5000 miles) and the average mpg is get is usually 24....between hardcore city driving 24 days and 1500 highway miles every month !!!

definately the reason why my mpg has been going down lol.

ionojimbo

your 15 mpg is better than my 13 even after seafoam. i only go up to 2.5k rpms too

Bayam0n

hey, I only notice a change in the sound when i redline, unlike most people that hear an aggressive sound at about 2-3000 RPM, does anyone know why?

Bayam0n

what is seafoam? sounds dirty and a really slimy operation.

swoosh

iTrader: (5)

mpg is only 13 ? what gas do you use ? tires ? do u drive with ur ebrake on ? what gear u drive in ? L ? tires pressures ? miles on the car ? oil change interval ?????

damn !!!

lol bro its the way you are driving

when i first installed my aem v2 i was gettin 12 city miles...its cuz i was flooring it and didnt realize

then my mpg went to 18

then i installed xlr8 exhaust and went to 11 mpg the first week...now im back at 18 mpg

ionojimbo

i use premium gas 93 octane i think from mobil one gas/ 33-34psi front and 32-33 psi rear/ yokohama tires brand new (dont know much about tire models) / of course my ebrake is down haha/ its auto but in semiauto i shift at 2-2.5k rpm (best range for max fuel effiecieny i believe) / 63k miles and oil is still new


so far im looking to changing:

spark plugs (NGK iridiums right?)
fuel injector cleaner

any other ways to improve?

Lol, are you sure you dont have brick's in your trunk? definately try some fuel injector cleaner.

michfib

just installed mine and im going 70 miles on half a tank of fuel so 15mpg isnt as bad

SpiderX1016

I doubt FI cleaners through the tank will work unless you do the real thing...

Just wait till you fill up to get your average and be easy on the pedal.

samplemonster

OP your "highway" mileage is the key to your problem because you claim to have received average mph in the 20s. You were obviously driving in some traffic.

That's not true highway driving. Report back when you calculate it for a 50+mph and you will see your mileage soar.

Try2Live4God

Are you supposed to get better MPG with a CAI?

swoosh

iTrader: (5)

man i have no idea why and how u getting such a low gas mileage !!! how many people do u have when u usually drive ?

this is what i would do.....when its time to do an oil change.....

1/2 can of seafoam in gas tank (when the gas empty light is on)
1/2 can of seafoam in the vac line
1 can of seafoam in the engine oil case

leave the car for 15 minutes.....drive around vtec-ing through the gears....get all the smoke out....

oil change

replace both the filters (cabin and air)

do a 3x3 tranny flush

rotate/balance/alignment

spark plugs

get ur tire pressure up to 35 all around....

Bayam0n

what manufacturer do you use for spark plugs? whats the best?

iTrader: (5)

NGK all the way !!!

aztec209

What was the model number for the V2 AEM CAI. I'm gonna buy one soon.

ionojimbo

i did sea foam already im waiting a month before i do it a second time. sea foam helped me improve by 2 MPG which i thought was well worth the money. and what is 3x3 tranny flush? is that drain then run the car then drain again and etc?

i will check my filters next time and check those and i do plan on getting an oil change a little later after my second seafoam

SpiderX1016

You don't need to seafoam it a second time. It's not some kind of miracle water that solves every problem.

Yes, the 3x3 is what you said. Drive the car for a while, drain, refill and repeat.

swoosh

iTrader: (5)

i just seafoam every oil change (5000 miles in synthetic )

3x3 is you drain 3 quarts and refill with new ATF....drive around in all gears.....and repeat this 3 times....i usually do a 1x3 every other oil change which is 10K miles !!!
