I did a search but didn't find any direct answers.

I know mods and even how you drive the Evo can influence the MPG rate.

So, basic question:

what is your estimated MPG with the new Xs?

 

yeah i'm also wondering this since the window stickers usually off a tad then the appear

 

I am not factory reflashed yet, but I have been averaging 16 mpg.

 

I just got the reflash and have only driven half a tank, but at half, I am at 146 Miles...

Before the reflash I was at approximately 115.

So you can do the math. This is with about half freeway / half street.

 

Got my X reflashed Saturday and it runs way better and better on gas mileage as well... It seems that the reflashed did it's magic on me...

 

I agree, the car does run a lot better.

 

So you guys are getting about 19-20 MPG? Again though, this number would depend on how you drive. If your a feather or a lead foot on the gas pedal.

 

Yes, it is driver dependent..

I have been getting 23-26mpg.

 

On the freeway I've seen 26mpg (according to the fuel economy computer). Just doing basic miles/gallons division...I've gotten about 23mpg as an average over the last 3 tanks (917 miles on the car). I did the reflash 1 tank ago, so I haven't gathered enough data on it since then.

Funny how gas prices influence gas milage posts. :-)

Honestly it doesn't bother me much since the Evo isn't my Daily. I use the data just to take note of any potential fuel system or overall engine issues.

 

I would say you're pretty close to 30 mpg if you feather an X on the highway with the new dealer flash.

 

I can agree to that!

 

Excellent!

That should be alot better than my 19.7 mpg 4runner


Although, I assume its very difficult to want to "feather" the Evo. hehe....

 

My STi gets around 16mpg, so I'm hoping for an improvement haha.

 

I did not notice a difference in the mpg BEFORE & AFTER REFLASH

I get <200 in full tank

 

might wanna stop living your life one quarter mile at a time, vin.
