Mileage

[PaHumBug]

When people ask me what my mpg is I reply that I don't know or care, that's not why I drive it. BUT, I get about 10.2 on this one, which is lifted and modded (CAI, exhaust, tune, 6" lift, 37" tires (plan to go bigger once these ones wear out), gears, etc). My previous stock ones I got over 12 mpg. It really depends how heavy your foot is, and how much you care about mpg... I tend to have a light foot, more so because I don't like beating my baby vs trying to be fuel efficient... I use 87 octane too.

Im about 1/2 way thru a tank on my 07 and currently averaging 15.4mpg.(yes its a H2) Ofcourse that is driving like an old lady with a painful blister on her right foot!
I also live in the mountains at about 7500 feet, would high altitude give you better mpg?

My CAI hasn't done anything..haha. I'm getting 10.4 currently with the mods listed below..I think it's mostly due to all the city driving I do. I live in a small town where it's a constant stop and go, not good for my case. And I must have a hell of a foot!

The thinner the air, the less milage I would think.

My catback system has been on for a few months now. I went from 11.7 to 13.2.

After reading replies from this post, I am going to remove the screen from the air filter and hopefully jump up another 1 mpg.

At 14.2 I will be a little happier and if I would quit driving 70+ on the freeway, I could even go slightly higher.

I was getting on average 10.8, driving fairly hard with a mix of city/highway. I have done a few mods and drive a little easier (not much) and I am now getting 14.2. But mostly I am getting 13.4 after the mods and driving the same as before. If I am on the highway and set the cruze and reset, I can get up to 16 if I go 55-60.

Mods - CAI, Exhaust, programmer (performance tune), better plugs and wires and electric fans
