Just an update on my wildly successful experience with the crosstrek in regard to fuel economy with mild levels of effort to conserve fuel…

The only precautions taken were to avoid harsh acceleration, coast to stops, take time getting to cruising speed, and not idle for more than a few seconds.

Completely stock vehicle.

I live in the Adirondack mountains of Upstate NY. I drove 113 miles yesterday, about 1/3 of which was off road under 20mph on dirt and gravel logging trails, with actually quite a bit of idling. Dash readout showed 37.7 mpg. Manual calculation (same gas station, till second pump click, 66F outside) was 37.6mpg.

Drove 90 miles today, 1/5th off road on logging trails under 20mph, lot of slow crawling up hills and winding through mountains, 65F outside, dash shows 42mpg manual calculation is 41.88mpg

the fuel economy is very impressive with a moderate level of effort, and also the dash is very accurate on my particular vehicle - I have heard however some others have issues with theirs being inaccurate.

to newbies especially wondering how the crosstrek can perform in regard to fuel economy, there’s a little insight based on my experience.

Wow! 42 MPG is impressive and it seems your Exaggerometer is pretty accurate too. Never got close to that, even on road trips.

 

That's better than I've ever had. I got 34 ish on a long roadtrip one time. My exagerometer is typically off by a little under 10%.

 

I find it very odd that there’s such a different accuracy level from car to car…

34 is right around my regular, without even trying for good mileage. In these winter months below 0F I’ve averaged 29 which I still think it’s pretty great for the way Subaru prioritizes emissions over the drivers wallet. Summer average has been 32-38 somewhere in there depending on where I’m driving. This is a new best for me, i definitely am curious if the engine is breaking in better now and contributing.

 

That’s impressive. My 22 Sport averages around 32mpg on my normal day to day commute. That’s 75-80 mph of mostly freeway. On my beach trip this weekend I topped off on my way out of town. Most speeds were 55-65mph but I was at 37mpg after 240mi in when I got back into town today. I even crossed the Coast Range both directions and played on the beach a bit. You are right, how you drive makes a sizable impact.

 

Nice! you must've been really nice on the throttle to get that kind of MPG. As for the MPG number varying from car to car you are correct. Every single time you reset the trip or driving pattern changes. your MPG/DTE will change real time as well.

If you do lots of city driving, your DTE will decrease quite a bit but if you do lots of highway driving, your DTE will be pretty high. I've seen it as high as 900km and as low as 500km.

 

Am i correct in what I’ve observed, that the DTE is calculated per reset of the trip odometer? I’ve noticed mine will show, say, 35mpg, distance to empty: 150 miles. I reset the trip odo, it will show 0mpg and no information for distance till empty. It’s my understanding that the computer deciphers how far you can go based on how efficiently you’ve burned fuel so far (since the last trip odo reset). I’ve seen this change in real time. Going through a lot of mountains it will drop to 15mpg average and say 100 miles till empty.
Coating later in the same drive, mpg average will go up to 29mpg, but 245 miles till empty.
Has anyone noticed this real time adaptation based on how you’ve used the fuel so far on this trip odometer cycle, it estimates how far you could go with what fuel is left…

 

Wow, that is amazing! I’m averaging 31.6 right now. I’m going to do my best to get to your level, master! 😂
