Yeah watching the instant MPG gauge helps me more than the colors.

Whenever I need to step on it I say "Time for BLUE SPEED"

 

Naw Naw Blue Speed is too slow. We gotta go right to....LUDICROUS SPEED!

 

Haha love it

 

Ludicrous speed?!? I don't think this car can take it.

 

Its nice to see consistent temps in the 40s and 50s. I love this little engine. Here's proof that it's finally getting warmer (this is a picture of my tank history screen taken after my morning commute today):

Wow, those are some impressive numbers!

 

The Current Drive mpg is a bit of a misnomer, that is the result of just 2 trips (35 miles and 25 miles) and both were with a tailwind. That number will be dropping for sure, unless I can somehow work it out such that I only drive with the wind. But, at least temporarily it looks pretty cool.

 

This is a non-issue. I can see a manufacturer eliminating that feature if people complain that the car doesn't agree with their calculator. Big deal!

That's one reason that temperature gauges went electronic and stopped giving accurate readings. People complained to the dealers that their cars were "running hot" when the needle move a little bit.

That's one thing I miss in the Fit. I like to keep an eye on the temp gauge, especially for turning on the heat in the winter.

 

It is most likely my fault, but I can't touch any of the reported mileage here. I've only driven my first tank so far, but my 2015 EX Manual got 26mpg. I was shifting when the colors would turn blue and do highway driving with 2/3 lights every day.

This tank I decided to ignore the lights and drive it like my Miata. We shall see what happens... I'm pleasantly surprised by the nice little throaty growl this car makes when breaking 3k on the tach.

 

I don't think my engine knows it can rev to 3K.

 

The ups and downs of the highways down here in SoCal really hurt my mileage. There's a huge difference between when I take a drive down to San Diego (I think 38 mpg is my best, round trip), and when I go up to Orange County or something (generally flatter roads, and usually 40-42mpg).

I just did my first oil change at 3800 miles - only did it early because of a several thousand mile road trip I plan on taking soon. Filled it with a Japanese-spec motor oil approved for the L15B which should maximize fuel economy. I plan on doing a UOA after 5K miles to see how the oil held up, and I'll also see how it affected my mileage.

 

My wife filled our new Fit for the second time today, both times filling it to where she could see liquid fuel in the filler neck. For that tank the display said 41.0 mpg, the calculation came out 39.4 mpg, so about 1.6 mpg optimistic. Same number as some have reported, although others reported no error.

Anybody know if it is a bad thing to fill the tank all the way to the top? She said both times she filled it, she was able to put two more gallons of fuel in after the pump first kicked off!! Concern maybe regarding fuel expansion. She likes to stretch the time between fills (her previous car was a VW TDI that would go 600 miles on a tank).

10.3 gallons went in shortly after the light came on, but I should think there was a gallon or more actually left in the tank for reserve. Rated capacity 10.6 gallons must not reflect a complete fill.

 

I always get about 1.5 gallons more after the first click of the pump. The pumps are all different but I've never seen anywhere near 2 gallons yet, that pump must shut off a little earlier than the ones I use. The most gallons I pumped in so far was 11.2, so yes, the tank has some reserve. And I won't fill mine all the way to the very top, I fill it to where I can see it at the top of the filler neck, but then it recedes a bit.

 

Definitely not a good idea. As you said, fuel expands, even when it's not above 90°. Unless you don't know where you'll be able to find gas for your next fill-up, what's the point?

 

Doesn't the GK have a vapor recovery system canister that could get damaged by overfilling? I know it's not very common that it gets damaged but if you overfill every time such that it gets saturated with fuel, it could damage it. But again, the fuel would have to overflow into the recovery system repeatedly for that to happen.

 

That was my concern, I'll suggest to her to go no more than one gallon after the first click.

SilverEX15, the point is simply to go further between fills, but obviously not worth damaging anything.

 

last week I tried filling up to the first click and the MPG was within .1 of the meter on the dash, but I could still add another 1/2 gallon after that to the 2nd click so obviously it was off by 2 mpg or so afterwards.

Also when I put the nozzle in, it's not inserted as far as it will go, it's maybe 1/2 way.

Edit: I filled to one click again today and it was within .5mpg of the dash

 

I had an old English car, a '52 MG, and there was one section of the owners manual that took me a long time to translate. "Do not fill the fuel tank until fuel appears in the filler neck."

 

Yeah, the owner's manual was correct. Plus, on modern cars (as mentioned above) there are other systems that can be more easily damaged than in the past by over-filling. Just stop filling when the pump clicks off.

 

First, what is GK? I've had my Fit EX for almost nine (9) months, and use the ECO option. I tend do mostly city driving, with an occasional highway trip. The computed MPG had been pretty spot on when I calculate actual MPG at full up. That said, I'm averaging only about 28 MPG, lower than what was advertised. And MPG for total mileage is under 30. Again, less than touted.
