Gas mileage improved by 5~6

zZSoCalZz · 05-25-2010, 02:46 PM

My first tank of gas from the dealer averaged 11~12 MPG. Since then I've installed a G3 CAI and used nothing but Chevron 91. Is this possible or maybe my tripOdometer is spazzing? Can someone shed some light on this?

I drive the same amount of miles everyday. Same freeways, local streets. I have about 1250 miles on it.

your ECU is adapting (amongst other parts breaking in) to the operating conditions so first tank is usually poor mpg... then things get better from there.

not sure about CAI.... usually they help because cars are programmed to run pretty rich in factory form.

You get better milage the more you break in the engine

zZSoCalZz · 05-25-2010, 02:55 PM

So it's pretty normal huh? I've never paid this much attention to my other cars.

11-12 mpg???? do you redline every shift or something? that is low.

Never passed 5k RPM for the first tank of gas.

No, he lives in Los Angeles. Stop and go, stop and go, stop and go.

Prior to my tune, that was the same MPG I was getting. I'm up around 14 MPG since then.

It does get much better once you get out of LA.

Yeah... I lived in Burbank for 3 years then moved out to Korea Town. Horrible traffic and bad drivers. lol

Burbank has better roads with less potholes too.

Oh yeah the women are delicious and the food is great lol. But yeah I've dated mostly korean girls and trust me its not all gravy. Some of them are crazy as hell! My last ex trashed my house and threw all my clothes out into the streets and told me to get out... It was my damned house!!!

I had the same thing. First week or so, 16mpg maybe. Reset the mileage gauge, drove some highway miles. It's been in the 20's ever since.

Chupacabra · 05-25-2010, 03:14 PM

Son of a goat son, that is low....

i do half highway half city, total of 52 miles a day... shift from 5-6k and get 19-20 mpg.

11 is low dude....low rider low.

Is this something I should be concerned about? All this time I was thinking wow! great improvement from 11~12.

m4a1mustang · 05-25-2010, 03:18 PM

Yeah! I average 19 mpg with bumper to bumper city driving!

Chupacabra · 05-25-2010, 03:32 PM

I don't think its a thing about concern as much as you are doing something wrong... you might be holding a gear at high rpms for a long period of time...

reset that part of the trip computer and start fresh... you should be able to easily hit 18mpg.

because at this rate you get what 187-200 miles to the tank?? i average about 300-320 miles to the tank...
