Re: Fuel economy...

Yea there's gotta be something wrong, maybe the gas gauge is wonky?

No way u can only go 250kms/ tank
Granted the top half always seems bigger lol

Re: Fuel economy...

That's the respond from one of the Managers at the dealer (who is a friend of mine) :

"You’ll want to allow approximately 15,000 for optimal fuel economy as new engines are programmed to run “rich” during the initial break-in period. I never pay any attention to the vehicles on board estimates, the best way is to fill the tank and monitor the average kilometres per fill – that’s the only way to get accurate readings. "

Do you agree ??

Re: Fuel economy...

Well I don't know about the first 15000 cause I've never owned a brand new car
But u should calculate everything by hand if u want an accurate reading of fuel mileage

And I know in my jeep I can go 250-300kms on the top half of the tank
Then 200-250ish on the bottom half

Re: Fuel economy...

I've monitored the fuel consumption of every tankful of fuel in four of my vehicles over the past forty years. From my experience this idea that fuel consumption magically gets better as the engine breaks in is an urban myth. On my vehicles, after the first 500 miles, the mileage is stable and there is no trend to any further betterment. The numbers don't lie (real fuel receipts and calculations, not EVIC readings).

Other factors like highway/city, headwinds, hilly terrain, towing, etc. etc. of course have far greater affect, than the engine break-in after that first tank or two.

Re: Fuel economy...

Thank you for the input. I filled the tank today ,first time, then I pressed the RESET arrow on the EVIC Fuel Economy display. The numbers became erratic, moving rapidly from 6.0 to 26 (at one point to 156 ...!!!!!) even when the car was idle in a stop light.....????

Re: Fuel economy...

Idling will always give you poor gas mileage. Just think about it. You're burning fuel but not going anywhere!

The WK only goes as high as 99 right after resetting, but starts to settle down to a normal range once you drive it.

Re: Fuel economy...

I just took it for a smooth short highway ride (only to 70-80km/hr.), and the Lit/100Km. dropped significantly to 14.9...!! I feel better now.

True. Pen and paper method is the only way to get accurate readings.

Exactly! Only thing to note here is the engine is tight for the first 500 or so miles. It needs to get all the parts worn into eachother to work efficiently with the least amount of friction.

Idling kills fuel economy....

Re: Fuel economy...

Any chance the Canadian models use the imperial gallon for mpg stats?

28.3 imperial mpg = 23.5 mpg
