Poor Gas Mileage on the 17 EX-L

Hello all. I love my new CR-V but consistently getting terrible MPG. I average right now COMBINED 20MPG. I am wondering if there is something more going on here. If I could get this up to 25 city I would LOVE my CR-V but as of now, I am very disappointed. Especially after hearing what other owners are getting. Any advice??

To verify if your MPG results are tied to the type and style of driving you do, try this:



Warm up engine. Fill up with gasoline. Record mileage.

Drive AT LEAST 100 miles at once. Recommend highway and rural roads. This will take you 1.5 - 2.0 hours.

On the way back home, fill up with gas again & CALCULATE the MPG by dividing the mileage traveled by number of gallons at fill up. (Don't use the mileage readout, they tend to be optimistic and lag in accuracy.)

POST the results back here... :eek:

4 things always apply, being an ASE tech I listen to it every winter:

Drive like a sane person, city streets arent a race track lol. When your packing a turbo its hard to overcome subconscious heavier foot. I know that WAY too well lol. You think your driving normal, bet money your actually driving like the other 10k jackasses and sucking fuel like mad to do it.

Check your tire pressures, when it gets cold tire pressures drop

Its winter time, different fuel blend and its cold, not going to get same mileage. Just like expecting to get max rated mpg city with AC blasting in the summer. Not going to happen. Things are cold, meaning stiffer, running heat etc. Adds up especially if you drive heavy footed.

Dont put the cheapest, especially ethanol fuel in your tank. Ethanol costs MPG.

I get almost 24 city in my 2003 in the cold right now with over 200k on it, and I occasionally drive like an *******. I also run no less than 89 octane, non-ethanol fuel only.

New hondas or old hondas, these rules have never changed in all my years with every Honda I or anyone I know has owned.

As a Honda owner since 1976. I have learned that Honda's do not get better MPG with higher octane fuels. You do get a little better MPG without ethanol but the extra cost does not pay because the cost per mile driven does not get better - it get worse - so it does not pay for itself.

That the 1st 4 miles on any trip get very poor mileage. These are typical MPG for a 2013 CR-V. I use cruise control when possible. I never turn off the A/C - even it winter as it does not seem to save money and it helps when defrosting windows.

mile 1 - 13MPG mile 2 - 16MPG mile 3 - 18MPG mile 4 - 20MPG .... mile 400 - 40MPG

I have gotten back to back over 40MPG driving cross country on trips. The 1st tank is about 32MPG but 40MPG on next fill ups as long as I don't let the car get cold. - you can see that in Fuelly.

Never go to banks or fast food drive thru windows - that cost you about 1MPG for every 3 minutes in line per tankfull.

I learn the traffic light timings to avoid racing to red lights. I get passed a lot between red lights but I get 28 MPG in town as I almost never have to stop at a red light. I also avoid rush hour - I would go to work early and leave late to avoid stop and go traffic.

The AC, fuel choice etc have little difference to someone who has the time and patience to drive to completely optimize mpg. 1 in a 100

For average driving (and 1000s of studies to prove it) AC compressor being active at low speeds in town, constant speed changes makes a HUGE difference. Which is why I remove my AC relays once temperatures drop enough its not needed. So it doesnt engage. Leaving stop signs and stop lights the power increase required to move is much larger.

Same with ethanol having no effect for you. Your driving in a manner water in the gas probably has no effect. Never going really above 3000 rpm if at all. Never needing real power from the motor.

Maybe for you the ethanol vs not price difference is much larger than the midwest, but its at max 10 cents per gallon. So at most 1.50 more for a tank. And when I gain 50-75 miles per tank the savings is 3-5x the extra cost.

Also you have to run a couple tanks of fuel and be using the engine to see the change take effect.

Premium is not much good in many cases. For these newer Turbo models it will make a substantial difference. If performance offsets costs has too many variables and is a per driver basis.

Like our odyssey. Around town makes little difference in fuel choice. Distance is too short to matter normally as we live in a more rural area. As I believe I said above, switching to premium 1 tank prior to road trip and then for the trip its mileage is massively different. First tank takes about 1/3 of it before computer adapts. Then increase is enough to balance out cost. Once road trip begins 75+ more miles per tank. Especially when loaded. Come out ahead saving a couple dollars or so per tank.

My CRV doesnt see that jump. Going full 93 premium is a waste. 89 non-ethanol is the sweet spot. But havent towed with it yet to see if 91-93 octane will show worth it for that purpose.

Also when driving, use the settings screen to monitor instant and trip mpg. You’ll be amazed how much it varies as you start from cold, accelerate, Cruise, lift off etc.

Same here for exact same 2017 CR-V. City is about 21 mph with careful driving, no rapid accelerations, coast downhills, etc. We are very disappointed with this as it is no better than the 2003 CR-V we replaced. On the highway, it is much better, of course. For pure HYW driving on along trip, we averaged 34 mph. What to do?

If you so much as turn your defroster on you loose gas mileage. A lot of vehicle to move on a small engine around town. As well as drive thrus, stuck in traffic at all etc all will drastically drop fuel mileage.

Something to accept, no vehicle gets the best mileage possible in cold weather. Add in snow or rain, wind and so on and mileage goes to crap.

One thing people dont realize is small engines do not mean better fuel mileage. Its small vehicles and new CRVs arent small, fair bit bigger than older ones but still get better mileage than older ones.

Personally I cant believe how poor the mileage is on the gen 2s. I may have passed on this deal and looked for a pilot had I known it was so bad. My wifes odyssey gets gets better mileage and it weighs a lot more.
