What can I do to my 2016 honda fit to get better gas mileage?

 

Lay off the gas pedal? Get a tuneup ??? ....so much we don't know

 

Google, google, google.

 

Just bought it 3 weeks ago with 41000 miles on it, so far I only flushed transmission and changed the oil twice...I don't drive erratic ...

 

Since you don't tell us what the mileage you're getting actually is (city/hwy) your question is kind of meaningless. Perhaps you're getting the best mileage you can ever hope to get.

 

Sorry... I thought I said in the first post, I'm only getting 34 to 35 on hwy if I set cruise at 75, I can get 37 if I set cruise at 70...all interstate, don't do enough in town driving to even bother looking at how much...

 

That's what the 2016 FIT with CVT is rated for on fueleconomy.gov
You also have to understand, the FT only holds 40 liters/10-11 gallons, so fuel-ups are going to be a little more often.

 

Well crap...everybody told me 37 on the hwy

 

I don't know how the cvt's are "geared" , but on my 5 speed, 38-45mph is really the sweet spot, anything over that and it starts to drop. 60 should be about the limit of "good" highway mpg, anything over that will just drop more and more.

 

Driving to get max fuel efficiency is the same as it's always been.
1) properly tuned and maintained engine
2) properly inflated tires
3) "adult" rates of acceleration and deceleration; look ahead and anticipate
4) maintain efficient speeds (e.g., 55 mph was originally mandated for fuel efficiency)

Depending on the aerodynamics and gearing of a vehicle, peak fuel efficiency will usually fall somewhere between 40-60 mph. Guess what, that Prius that just passed you doing 85 isn't getting 54 mpg, and that F-150 that just passed the Prius doing 90 is probably somewhere around 10 mpg. If you're getting 37 mpg at 70 mph, which you said is what you were expecting to get, what's the problem exactly? If you want to do better slow down.

I will add that cruise control may or may not help your efficiency. It all depends on terrain and driving technique (the anticipation I spoke about above). When I'm controlling the car and see a hill coming up I can increase speed a bit on the flat and let my speed fall a bit as I get to the top, knowing that I'll get it back from gravity after cresting the hill. Cruise will downshift multiple gears (I have an A/T) to try to maintain speed up the hill, which definitely decreases efficiency.

 

Personally I find that cruse control hurts fuel economy a lot. Mostly because on up hills it accelerates like crazy and downhills it brakes. I'd rather be a little slow at the top of the hill than have a constant speed. If you have the eco button on maybe try turning it off. Depending on how you drive it might be helpful or not. I don't drive with the AC on but if you do, the car seems to indicate that it's affecting the fuel economy. After that, you can pull the rear seats if you don't use them but that's a personal decision.

 

I'm not sure how folks are getting into the mid 40's on the highway. In the summer, the best I can do with my 5sp MT 2010 is in the low 40's.
The key to good gas mileage was just stated above. This means that you will not be the first to arrive at your destination. Slow take-off and slow deceleration. Even speed and slower speeds. The faster you go, the more wind resistance you encounter and the lower your fuel mileage.

 

Turn off Eco mode.. I was getting 36-38 mpg with it on. I turned it off and get 41-43 now.

 

I drove the speed limit this weekend. 55 or 65 depending on the road. Usually when I fill up the car says my range is 300-330 miles. This time it indicated over 400. Since the range is based on some recent driving history that makes me think that I was getting much better mileage at those speeds.

So yeah, not driving 70 will increase your mileage a bunch.

But if there were simple things to do to get better mileage, Honda would've incorporated that into the car.

 

Around town I routinely get 40-42. If my kid drives, then its more like 33-35. The driver matters.

 

I too have a 2016 Fit, 32k miles. Ours has CVT which was supposed to get the best mpg. At times in the past I have gone on a 275 mile trip, running about 65 mph, and gotten 52 mpg. Yes, fifty-two. If it is winter, or I am a little heavier on the gas and go 70 mpg then I'll typically get in the mid to upper forties. Right now we have an old set of tires in not so great condition and on our last trip at 65 mph I was getting lower forties.

As FitAnotherWay mentioned, turn off cruise control. Also go at a lower speed. If I drive highway averaging about 65 then I can ease up a bit on the gas while going uphill and reach the top at 60. So what if it is slow? If I go downhill I can take advantage of it and make up the lost time by going 70 mph and still be in the green zone. Going about 3-5 mph slower than other traffic is also nice because I almost never have to worry about passing somebody. No rapid acceleration.

Of course mileage will also depend upon the terrain. Where I live it's mostly level with a few places up 100 feet and down 100 feet.

It also depends upon the driver. I learned how to drive in a VW camper bus. My last car was an '81 Corolla. Even 55 mph in that feels fast. It wasn't a muscle car and I am beyond the age where I feel I need to drive like I own a muscle car. I am used to the slow acceleration of older cars and accelerate like that even with our Fit. That helps with getting a few extra mpg. My wife is definitely more positive on the pedal and when I drive around city I tend to get a few more mph than she does.

There's many factors which you haven't mentioned that could be affecting this. Do you carry a 10 bags of cement in your car?

 

Don't use the brakes. Like hardly ever.

If you drive 10 miles on the highway at a time, like I do often, and burn say 1/4 gallon (ie 40mpg for simplicity), how you stop is a big deal. If you coast down from 70 and that is the last 0.5 mile of your trip with no gas burned, you've gone 10 miles but only used gas for 9.5 miles of it. If you wait till you're in the exit lane and brake, you've burned gas for a full 10 miles and then turned that last half mile of gas into heat.

That's 40 mpg instead of 38. Big difference? Up to you I guess. The numbers get more impressive the more frequent the stops are, ie if there's traffic or lights.

I will say tho, on my 2012 I used to be able to beat the EPA easily, but now the car is older I basically get what it suggests for the highway -- 33 mpg. IMO this is not stellar, but it is what is achievable given a ten year old car designed five years prior. If you are hitting the EPA 37, then anything beyond that you're in "extra credit" mode and have to start looking at hypermiling techniques like my suggestion. Lower front spoiler also helps :P For most ppl this stuff is not worth the tradeoffs.
