I drove 711 miles from home to Cape Cod, around the Cape, and back home. The screen in the car showed 46.6 MPG, but my math showed 44.4 MPG. That included driving 65 - 70 MPH, construction delays, and traffic and lights in towns. I'm surprised and extremely satisfied. As you can see below (from Fuelly), this has been typical of my mileage. My Garmin GPS showed 37 minutes "not moving," so for 37 minutes, I was just sitting, idling, burning gas but not moving. I can see the advantage for those cars that shut off the engine when stopped.

 

That's still pretty awesome MPG!

 

"Construction delays and traffic".... that's putting it mildly, I imagine. (-: Next time, wave as you drive by.

 

I did!

 

Dang. Sorry, I must have been being one of those unfriendly New Englanders that day. laugh.

 

I guess I've never run across one of them.

 

Well now, that is nice to read!

 

Geez Silver, u must have little traffic in your area. Traffic for you is probably like a normal day here in SoCal. I can never get that kind of MPG unless it's 90% highway. Is that trip with AC on?

 

Was this trip just you or did your son follow you in his car?

 

No, he's my son, not a siamese twin. He does more stop and go driving, and he doesn't care about getting the highest MPG.

 

Traffic kept moving, except for construction and later an overturned truck. The AC was probably on 75% of the time.

 

I was wondering what accounted for the difference in your MPG statistics. That explains it.

 

That is awesome!

 

I'm still on my first tank of gasoline (have had my '15 EX CVT exactly a week). I'll check the math when I fill up, but my on-board tank average is sitting at 40.1 mpg, and here are the numbers from yesterday's drive to work and back home. For some reason, I am consistently getting better mileage coming home than going, despite the elevation at work being lower than at home…

New Fit, manual, driving 1500 miles. Mountains, freeways, curvy little mountain roads: MPG: 42; 44; and on one trip over the Sierra Nevada, heading down to Sacramento, with 80% downhill, 58! I drive conservatively, 60-65 mph. some road work stops of 5-10. I do shut the engine off.

 

First, it is difficult to refill to precisely the same level each refill so until you average many refill mpg's you really don't know accurately.
Additionally the mpg counter is not perfect either.
Either way its an approximation of mpg.
