MPG's not right?
 

So I just bought a brand new 2014 mitsubishi outlander sport right off the line. Let me just say I love it! However the MPG's are not adding up. The computer says I'm getting 26.3 and when I do the good ol math I'm getting around 21. I have 1336 miles on it. I do about 50/50 highway and city. I feel like I should be getting more out of it. I do drive very conservatively. What is going on?!?! Did I get a lemon?!??

Welcome to the forum.

Congrats on the new purchase.
Break-in period is usually around 1,500 to 5,000miles for our CVTs. ( I know, I know it's a wide spread, but that's how it is.)

Are you 4WD or just FWD?

Here's my documented thread on the matter >

It's a FWD so it should be getting wayyyy better than the awd, right?

Our 4WD system can be switched off to be only FWD if we so choice - to save fuel.
However, FWD only Outlander Sports have the benefit of larger gas tanks.

So, what variables did you use to calculate your MPG?

You're not the only one. I haven't been able to break 22mpg driving mixed in 2WD

I have the tire psi at 42. I have 87 octane in the tank. I drove 190 miles and filled up the tank. Averaging around 21. Wtf?!?! Do they make k&n filters or setups for the 2014?

Okay.. It seems you're calculating incorrectly.
You didn't mention the quantity of fuel used...
How much fuel did you have to put in (to fill up your tank) after you traveld 190 miles?



M ÷ G = MPG

Take actual miles traveled divided by gallons of gas (burned) equals MPG.


Just for kicks, I'd made some calculations -

1. IF from completely empty 16.6gallons, then you get a horrid 11.445 MPG!
2. if from 1/4 tank (12.45 gal) which = 15.260 MPG
3. if from half tank (8.3 gal) which = 22.891 MPG
4. if from 3/4 tank (4.15 gal) = 45.783 MPG

I'm going to guess you didn't have to fill up - completely from empty. So, you can get anywhere between 22.9 to 45.8 ( in "idea" testing & controlled environments, of course. ;) )

Yes that's what I did. Good ol fashion calculating. It only took 8.9 gallons, so I took the 190/8.9= 21.****

Is there any k&n filter out there for the 2014's??

How many miles are on your outlander sport?

Where is this break in period range coming from? Empirical data from owners?

I've said this before but there are OS getting book mpg right off the car lot and others a good 10+mpg below consistently, I suspect most of this variance is driving style and conditions but there's possibly something else and I don't think it's 'break in' related. I'm not entirely convinced there is a break in period beyond 500 or so miles that manufacturers often quote.

I don't own an outlander but this seems a bit weird for a relatively new vehicle.

From owning two brand new 2013 O.Sports SE AWDs (with the same packages, off the lot with just 10 miles on the ODO each) only difference was the color and the date when we took delivery.

We were able to achieve equal and better than EPA on the first one within 1,500 ODO, Real World driving both city & highway mix (BUT definitely NOT before this mileage was reached). The second one took a LOT longer... in fact we still haven't really bust through the 32MPG mark that were achieved before - going the same basic routes.

Along with several other members who's documented their observed increase efficiencies after a certain mileage was passed.

Over 9,000 miles now

Well that's a very small sample size. The thing is, an engine break in period doesn't last for 1000's of miles and they're normally consistent, not some cars 1000 miles, others 5000.

This theory just doesn't add up, take a look on fuelly for instance. There are 44 OS on the site and there are many cars getting 29-30mpg right from the start.

Just trying to make sense of the variance, not attacking you by the way...
