I just bought my new 2011 Fit Sport on Saturday. I allready went through a full tank of gas (356 miles) and put in only 9.5 gallons of gas. That equals 37mpg. I'm still breaking in the motor. No real secret on getting this MPG. I do a lot of freeway driving. Cruised around 70mph with the cruise control set. Never went over 4k RPM's. Accelerated gradually.

 

This is NOT how you break in the motor. You need to vary engine speed (RPMs) and shouldn't use cruise control during the break in period. Gradually keep adding RPMs too, not just keeping it low all the time. Doesn't mean you're running at redline all the time, but you want to blip/raise the engine RPMs up from time to time.

 

I'll bring up the RPM's a bit tomorrow.

 

Here's a reference for you...

New Car Care – How to Take Care of a New Car - Popular Mechanics

Gone are the days one should baby the engine during break-in, but you don't have to beat it up either. Variable engine speed/RPMs, with occasional (couple of seconds) running at higher RPMs (raising it past 4000, say to 5000, then 5500, etc) helps seat the piston rings.

 

My first tank around town short trip driveing with AC always on was about 36! I have never got that good mpg again JIm 0311

 

I appreciate the inner workings of an engine, but doubt it takes more than a couple hundred miles to seat some rings. The day after we bought our GE8, we drove 600 miles on the highway at 70-80 mph. I changed the oil, and put another 4500 miles on it over the next 3 weeks.

It's got 68k miles on it now, uses no oil, and runs fine. Just drive the damned car and change the oil.

 

Nice gravedig for your first post.

This has got to be one of the more classic debates in the automotive industry. If it works for you, then great.

 

Damn Son!!! have you never been on a forum before?

 

If there is a secret, that's it. The Fit spanks on the open road. City/suburb, the numbers pull back some. Still though, all good.

 

35-36 mpg here in metro Atlanta rush hour. Mix of city and highway. I haven't taken it on an extended highway trip yet. When I do, I'm almost positive I'll be in the 40's.

 

it's only six months old... at least it wasn't like the other person that dug up a 5 YEAR old thread.

(=.=)"

 

That's what I expected. But two runs to LA and Las Vegas prove the car just wants to average 35 on long trips. I think it's the higher speeds. I get my best mileage at 70 miles per hour or less. Pushing it to 75 or above really tanks it from 37-38 MPG to 33-35 MPG.

If I go about 60 MPH, I can get 39. But that's the best I've ever done. Changing the oil helps. I ran my first oil right to 10,000 miles when the wrench icon comes on. I've been stuck around 34 MPG. Now my car is getting 38 fairly effortlessly. So I do think oil life plays a big role in that motor.

 

You first oil change has all the shavings and particulate matter from when the engine was assembled and tested at the factory. All that crap probably got flushed out when you changed it.

 

Probably so. I remember how effortless the engine felt after pulling away from the stealership service center (1st oil change was free, though). And now my meter is still averaging 38, even with a good chunk of suburb driving.

 

I think it also has something to do with that avg. fuel economy gauge. I know im not the only one who watches it and trys to get a high score like its a video game

 

Hey guys! I'm on the market for a 2012 fit sport now and I'm trying to pick between a manual and an auto. I see lots of people posting great mileage, but I can't tell who is driving a manual and who an automatic. Is it possible to get the near-40 numbers with an automatic?

 

My neighborhood is embedded within a golf course, so I keep going for the low score.

 

If you drive mostly highways, possibly. If not, then not as much.

 

For the love of GOD buy a Manual. Save the sticks people.

 

Interesting. I'll definitely find out in May. We're heading on a long trip to the east coast of GA. I filled up tonight and did 36 mpg this tank.

I'm really impressed because, ATL traffic is just awful. I drive in the teeth of it in the AM and PM. Ugh!
