Well if driving around In-City at 25-30 mph is "not figured into the test" - I can certainly tell you why . It's because the mpg would suck majorly . Today I drove it about 8 miles in city ... with my shoe off the right foot so the sock could ever so slightly touch the gas - as light as anyone could possibly manage . I managed to get 20.1 mpg . Extremely slow starts from stop and very gradual - soft as a baby...coasting as much as possible. It's a total lie that these cars will get 28mpg city and 28-30 combined . I personally , from my experience think Honda should be sued for this. Driving in a normal [not hot] manner will give you about 17 mpg or about 11 less than advertised .
2017 CRV AWD. I agree with lightblue, difficult to get more than 16mpg in Seattle 'city driving' – EPA apparently uses flat cities (LA basin, Kansas, etc.). Mileage picks up if you include more highway driving to boost the average MPG. I convinced the wife that the CRV was a good option to getting a smaller hybrid. She wanted WAAAY better MPG, so I'll be paying for that decision now – she's pretty disappointed. I'll probably never hear the end of it. Next car maybe.
 
If your using the trip computer on your car to get your mileage IT'S not accurate......It will be off by 2-3 mpg
Do your computing by how much gas you put it and divide that into miles driven
I have done this by using monthly driving ,,,total miles for the month divided by monthly gal. of gas purchased
 
I do not doubt your measurements showed a 2-3 MPG difference. But for my first five or so tanks I found my car's calculations were +- .1 MPG so I no longer bother with calculator. I admit the geek in me does cause me to do a mental calculation while filling the car. Still very close to car's figures.
 
800 miles on an EX 2WD. Three tanks of gas. I ran the numbers (dividing the old-fashioned way) today from my three receipts... just over 28mpg on all three tanks... which jives with the displayed history +/- .1 mpg so far.

I've had a good bit of city short trips, and some hwy driving (a couple of road trips, 200 miles+). I'm trying to be mindful and not just floor it. I would have thought I'd be getting better gas mileage based on watching the displayed numbers over the lifetime of a tank -- not unusual for me to see over 33mpg; but also lots of short trips that don't have time to get there. The But I am sure I sat in the car in a parking lot for quite awhile with the a/c running, talking on the phone several times.

I'll have to try ECON mode.

The tough part about any short trip is that starting from cold is on any car a guzzling time. Set you screen to system and watch how the mpg improves during the first few miles.
Makes you think the mpg tests start with a hot engine.

We also don't get very good mileage... 22.7 overall with 2k miles. Our driving usually consists of less than 15 mile one way trips, with lots of stop and starts and hills.

For me, I don't see how anyone can drive the same route and get anywhere near 30mpg in MY vehicle. I already begrudgingly employ hyper miler tactics to achieve this number, and I drove my 2002 EX AWD MUCH harder and always got 23 or 24 this time of year. I am convinced it cannot be done in MY vehicle (Touring AWD).

With that said, has anyone tried driving a different CRV of the same specs on their usual route? I would love to borrow a loaner from the dealer and drive it the same route to determine if it does better. Is it my strange combination of stop and starts and locations of the hills at the start, etc... causing this problem? Or is it possible a few CRV's have some ECU or overly tight specs, etc.. causing poor mileage just in those particular vehicles? Would love to know.
 
As for the poor fuel economy reported for those who do short trips, I'm pretty sure it is not reflective of the actual fuel economy (which should be much better). The culprits are likely the "sensitivity"/"resolution" of the fuel sensor that measures consumption and also any heuristic predictions that the system's computer is making on fuel consumption. For example, let's assume that the fuel sensor can detect changes in fuel down to approximately 0.5L, but not less (I'm using metric because I am Canadian, and you should also because it makes so much more sense :)). 0.5L will usually get you about 5km in the city. So if you're trip is, say, 2.5km and you've only used 0.25L of fuel, its possible that your sensor has not even detected the consumption. Based only on this information, the fuel economy would be infinitely good (some km divided by no L), but the system knows to compensate by hazarding a guess at your fuel consumption based on average statistics, your own previous driving habits, etc., all of which are inherently inaccurate. My suggestion to those driving only short trips is to calculate your fuel economy yourself; your total distance divided by the amount you fill up.

would a K&N air filer help with gas mileage?
About ~3-4mpg improvement in my experience. Last time I looked they only had it for the 1.5 liter. I only have 900 miles on mine, I want to get an idea of mpg stock before I get one.

Make sure to tell service people to not change filter or they will throw it away and put an OEM filter on!.......:eek:

So the engineers at Honda are not smart enough to know that they could have increased fuel economy by 3-4 mpg just by sourcing a different filter?
 
Car companies spend millions of dollars trying to get the very best mileage they can out of a car. I remember one year at GM I heard how they had spent a few million bucks to get .1 MPG better mileage on their corporate fleet economy. If Honda could get or 4 miles per gallon better by changing the air filter they would. Of course less restriction in the intake can change mileage but perhaps there is a side effect that comes with this? Oh, like fine dirt getting through the filter and accelerating wear on the engine perhaps?

Honda, and all other car makers, have durability concerns as well as fuel mileage considerations. Perhaps there is a reason they use the filters they do. I will leave it to Honda to explain their thinking but my experience in the industry is that many factors have to be taken into account on such matters.

That's what I was thinking hans, the manufacturers spend 10's of millions to increase their CAFE numbers by .1 mpg but they completely overlook the low hanging fruit. All they would have to do is a quick search on the internet and they could increase their fleet average by an easy 10-12 mpg.

On the internet, changing an air filter is always good for an additional 3-4 mpg.
Putting nitrogen in the tires instead of air would get them another 3-4.
And we haven't even mentioned spark plugs yet, I put E-3 plugs in my truck and increased my mileage by 5 mpg... And it's a diesel!:confused:

What is the science behind getting 3-4 MPG from using nitrogen rather than air in your tires? I have to throw the BS flag on that one.

I am aware that having tires inflated to the correct psi affects gas mileage, but gas mileage is not affected by whether or not it's nitrogen or air that is the gas being used in the tires.

I guess it didn't come out right Jeff, but that's what I was getting at. Maybe I'm just getting old and cranky, but I think all these anecdotal internet milage claims are BS or the factory engineers would have already incorporated them into their vehicles.

I was talking to a guy one time though that told me to my face the mileage on his Chevy S-10 increased from 20 to 24mpg just by putting nitrogen in his tires. I didn't get the impression he was trying to pull my leg either, I think he truly believed it. I guess when people spend their money on the latest and greatest gadget, you can convince yourself of anything.

Now don't get me started on Slick 50, I still swear by that stuff.:D
