Just reached 20,000miles (32,296km) and did use 1895.8L gasoline.

This is 17.036 km/L or 40.07 mpg (US)

It could be better, since my working way is daily 4 x 5km, a lot of the distance is done in the warm-up sequence of the engine!

 

"Worst tank filling = 6.657 l/100km
= 15.022 km/l = 35.334 mpg (US) = 42.436 mpg (Imp.)

The worst tank was during wintertime, with AC 100% switched on.

I can’t complain about AT either :-)"

Why would you have the A/C on in the winter?

 

The A/C takes humidity out of the air. Keeps the windows from fogging up.

 

In the winter, the defroster will run the compressor a tad to remove humidity, but it's not the same as "having the A/C on"...nor does it suck gas as bad. AND...it's usually a temporary setting. I realize that winter in Hawaii isn't the same as winter in Canada...but still makes no sense for a Canadian to be running A/C in the winter.

 

It's exactly as having the A/C on... compressor cycle time is the same in the defrost setting as turning on the A/C via the switch.

It is not a "temporary setting. If you have it set to "defrost" the A/C runs as if you have turned it on. Show me where it says the cycle time is diminished in the defrost mode? I've never seen anything to confirm this. In fact, there are many on the board that have gone out of their way to disable the A/C function when in the defrost mode to improve gas mileage. The only thing needed to do is to take off one wire from the defrost switch that enables the A/C when in the defrost position regardless if the A/C button is depressed or not.

I'm sure it's not the same (thank God ), but humidity is humidity and humid air in the cabin will fog up the windows... especially if you are running the heater, as I know you are in freezing temps. In your case, I would think your humidity is higher in the cabin due to you dragging snow into the car on your shoes and it melting into puddles in the car. If I were in that condition, I would most definitely run the A/C along with the heater to get rid of the excess moisture in the cabin air.

 

My point is that once the windows are clear, you switch back to the HEAT...of course that's in COLD weather...not humid, or wet conditions. In the cold of winter...the air holds no humidity. The only reason it's even in the car is because of you! (unless the car was in a warm place and your taking it outside).

 

I don’t do that either, if there are 'normal' conditions.

But at this particular day we were driving home from ski holidays.
It was heavy raining during loading the wet stuff into the car, and the 3 passengers and I also did bring a lot of water into the car.
No way to switch of the AC during this ride!

 

Just had the valves adjusted and new plugs on one of the '07 Fits with 207K on it. We are gettting 37-38 MPG's.
This is on two lane northern plains (windy) backroads at 65-70 MPH. This particular route has 25-50 miles between stops and the stops are no more than 10 minutes per place.

 

Last check on my '07 Fit (has automatic trans) yielded only 31 IMPG (combined city and highway) it used to do better when we first got it, and the mileage on the odometer is still relatively low (about 20 thousand miles).

I've ensured correct tire pressure and don't drive hard on the pedals (gas or brake), so I am a bit disappointed with this result. My brother has been getting better results with his Nissan Versa (also an automatic but the CVT).

later,

 

The cycle is diminished in the winter because of the outside temperature. The compressor won't operate below freezing (I think it's more like below 40 degrees Fahrenheit). Below 70 degrees the compressor runs infrequently to avoid freezing the A/C's evaporator.

That said, running the A/C with heat is the most effective way to defog windows in weather above 40 degrees. That and don't leave the outside air selector on "recycle." Amazes me whenever people insist on leaving their car's heating on recycle and drive around with foggy windows (my wife does that ).

Oh and I'm averaging about 32.5MPG on the 1st three tanks, automatic 09 base, calculated, daily commuter (50 miles RT) in metro atlanta.

 

31 IMPG is 25.8 US MPG. I'd have alignment checked and the engine diagnosed, unless you have gremlins driving it hard when you're not looking.

 

I've got a 2009 Fit MT, base model. With hypermiling, I've managed to get the lifetime average of the car to just over 42 mpg.

 

i went from kansas city to topeka kansas and was going 105mph at one point and still got 27mpg i love my fits gas millage had it in s and was hauling ass

 

i average 37.09

most 37.1

least 36.3
