Sorry to bother yall, and really want some helpful advice on the next steps.

I've owned some great Imports (turbos and NA) through the years and have consistently - based on my driving style and habits - ALWAYS surpass the high-end of EPA's miles per gallon (MPG) estimates.

That is, until I started to own my 2011 EVO MR. What is the deal here? Here are some facts:
- AVERAGING around 20 MPG; calculated from total miles driven (since previous fill-up) divided by number of gallons displayed at the pump.
- 100% stock under the hood.
- Only suspension mods on the car, which were done by the previous owner:
a. swift racing springs
b. rear sway bar
c. rear end links

Could it be the car was previously modified (then returned to stock) and tuned? Assuming the tune was NOT returned back to stock, therefore causing the discrepancy? Searching around the forum, I was not able to ascertain concrete figures, thus wanted to ask the members. Some members were able to get up to 28 MPG, which leads me to think something is wrong with my newly purchased used EVO.

I was thinking about bringing the EVO to a Mitsubishi specialist and have them look at all the variables that may negatively impact the MPG of the vehicle, including past tunes. What are some things worth bringing up to the specialist?


Thanks in advance.

 

I'd say sure, the car could have been modded and tuned and then returned to stock. That said, if it is still tuned for X mods and no longer has them, I would imagine some driveability issues associated.

Stock I was getting usually 20-22 overall, I have both highway and a good amount of around down in my commutes.

Tuned with full bolt-ons I am getting 24-26 on the same commute.

I would take your car to a performance shop to have it checked out, there are several great ones around MD/PA/VA to choose from.

 

GSR here, still 100% stock, 18-20 MPG driving it like an evo.

If the car was tuned and returned to stock without returning the stock tune I imagine it could be running rich, wasting fuel.

 

Nothing wrong about our evos. it is our right foot, that matters lol. I was able to manage a 36+ mpg on 60mph 100%hwy driving on my modded 2011 X MR (drop in filter, fmic+pipe, full turbo back and a tune @ EvoD). But on the other hand, i got 5mpg on the track, oops...

 

I get about 15-20 in the city depending if I drive it like a granny or an evo owner. And always get around 23-25 on the highway.

 

I miss having a stock boost gauge.
My best mileage in the VIII was accelerating just below boost (e.g. about ambient MP).

The X has a lighter turbo spool, so it's harder to tell when it's starting to go on song.


But it's kinda moot, for me.
The X gets slightly better mileage than the VIII.
But, while I got about 25-26 MPG around town with the VIII in MA, that plummeted when I moved to the DC stop light forest.

I was getting about 11 MPG sitting at mistimed traffic lights in the DC metro area in the VIII.

I've gotten as much as 14 MPG in the X in the city (between lights), ...
... but that drops to under 10 when I get stuck behind someone who thinks he's "saving gas" by idling down the road.
(People worried about "jackrabbit starts" "wasting fuel" ... in the accelerator pump ... in the carburettor ... that we took off cars 30 years ago.)

 

Your mpg seems fine to me. I get 20.5 hand calculated and that's driving like a grandpa most of the time. People saying they get 28 mpg must be driving 100% highway.

 

20 mpg is good. I'm lucky to get 15 mpg.

 

I get 17mpg and thats all highway driving at 70mph

 

One thing no one mentioned is the x is pig rich on stock tune--If it really bothers you get it tuned. But it sounds like you are on the money with what you have now-- you might be able to get a few mpgs hwy but about 20 is normal city. good luck.

 

It seems to me that people who say they get high gas mileage are probably reading the meter on their LCD display in the gauge cluster. That number is not accurate, imho. And can only be used to indicate your immediate driving habits.

If you are counting miles between fill-ups and dividing by gallons purchased, it's much lower. The best I got once was 22 MPG (long freeway trip) and usually average 16 MPG or so. After getting tuned for e85, the average went down to 12 MPG. :O But well worth it.

 

Fat tires on heavy cast (sic: cheap) aftermarket rims will make a big difference to your mpg especially if you drive spiritedly. What rim and rubber you on?

 

Stock BBS with all season Potenza RE97AS, 245/40/18 All Seasons. Maintained at roughly 36lbs.

 

My average according to the readout is 12.7

I always smile when driving for some reason.

Thinking about getting sticker for back window: "FOR EVERY GALLON OF GAS YOU SAVE, I'LL USE 4"

I nearly flipped my coffee and scalded the person next to me when I saw the "36+"

Do you mean to say 26?
