So I've been attempting to monitor the MPG I've gotten for the past few months.

What I've noticed is that the car tends to give me 3-4 higher MPG than what I work it out to be.

Bear in mind, this is a Honda Jazz 1.4 which I assume is more economical than the US one.

But through about 60% motorway/40% city driving, I managed 43.8mpg although the car said 47.2mpg.

I only managed 321 miles before the light came on so there was plenty of fuel left for another 60 miles but I can't resist to refuel when that light comes on.

Refilled 33.29 litres for 321.2 miles.

Any other experiences with Jazz?

 

Does the UK Jazz have an in-car fuel monitoring system, or are you using something such as a ScanGauge?

Either way - great fuel economy numbers!

 

I think the euro Jazz has a fuel consumption display built in.

Tekki: Are you calculating/converting with Imperial gallons or US gallons?

 

1 liters = 0.264172052 US gallons
33.29 liters = 8.794 gallons
321.2 miles / 8.794 gallons = 36.5 mpg
Not bad... but not 40+ mpg.

 

Ah seems so!

I always thought the Jazz was more economical than the Fit but I can never seem to get any decent MPG!

And the car has a built in MPG thing which is usually 2-3 higher than what I actually get.

 

c'mon i just did 360 miles on a tank with the 1.5L a/t slug, you can do better! (about 205 on the first 1/2, and 155 on the last half.) well that was like 95% freeway. some cars you can "tune" its mpg estimate by telling it that it's too high too low tank after tank. But still, 36.5 in mixed driving is freakin' awesome!

 

Well perhaps, but I primarily do a lot of short trips about 2-4 miles and about once a day.

If I ever become rich or decide to pollute the environment for no reason, I might just do a full motorway run and see how it goes.

Or I could actually find a reason to leave the city.. but I have no reason to :/
