Make sure your tire pressure is set... You want it at the highest rating the tire can take. The ride will be a bit rougher, but you'll get way more feel of the road too.

I regularly get over 40mpg with my 2009 Fit MT. My wife gets around 32-33mpg with her 2010 Fit AT. The manual makes a huge difference -- the automatic shifts WAY too aggressively, even if you try to drive slow.

I get about 35mpg when I'm towing, as long as I keep it below 65mph.

How fast are you going? Air resistance increases drastically at higher speeds, so if you keep your speed down, you'll get way better mpg. I had a 46mpg tank going to the beach -- all highway at 65mph. It was awesome.

 

I just bought my '10 Fit last month. LOVE the car. Had been driving a 2003 Buick Century, and routinely getting 28-30 mpg based on my typical driving. Was a bit surprised that the Fit was getting the same kind of mileage - BUT - that was during the frigid Chicago polar vortex blast. I had learned the pulse and glide thing long ago when gas spiked to $4 a gallon several years ago.

This last tank of gas was different with the Fit, and I changed three things, so I'm not sure if one or more are what made a difference:

1) I made sure the tires all had the right pressure (I don't know if they did, my gauge in my car didn't work, so I guessed and slightly over-inflated, drove home, then let air out to the proper 33 psi).

2) I filled up at a different gas station.

3) This isn't a change I made, but the weather has been about 20 to 30 degrees warmer.

My mpg went from 30 for most of the last 4 or 5 tanks (almost to the tenth) to 35.3 this last one. I'm guessing it might be all three things, but it's hard to know for sure.

One other thing I noticed: Wind direction matters, as does the surface you're driving on. I live in the Chicago area. The interstate by me, I-57, I tend to get worse gas mileage on no matter whether I'm driving north or south compared to driving on I-294, which is more of a concrete-surfaced road. When I'd fill up and drive a ways on it, the gauge would tell me 36 or 37 mpg (I had it up to 41 mpg this last tank of gas before I had to get off the road and stop!). On I-57, I always, always, always got worse gas mileage - barely over 32 or 33 most times.

Different roads, different friction. That's my experience. Oh, and hi! Nice forums.

 

I know this is going to get some differences in opinion for what I do but I've owned 13 Honda/Acura's since '98 and some cars needed this from the factory and some didn't but I get the best mpg when I 1. Add 2psi extra in the tires and 2. Use premium fuel. Not exactly for the added octane (which all hondas vtec.net has tested in cars using 87 made nice to big gains "J-series V6's" w/ 93) but for the detergents that keep the fuel system and injectors working at top efficiency does a lot. For a 10gal tank you'd only spend another 4-5bux if that. Now usually in the city, I run plus (89) but on freeway when you're running the L15 in its "sweet spot", you'll be using less fuel making the same power. For example, I just got my car last week. For the 75mile drive to take the car to have my hand controls installed my local dealer put 93 in, the car got to my disbelief 40mpg. This is still a "green" engine. I can wait to see what the car gets on a road trip @1000mi on the odometer. Just my .02

My first couple tanks were in the high 30s, then the weather suddenly got above freezing and I got two tanks over 43. Now it's cold again and I'm seeing just over 40.
