Thanks for the input Richard.
I'd be happy with a 10.4L/100Km city driving.

Heck i get better fuel consumption with my 2009 Pajero, that's a heavier car (4x4) with bigger tires (all terrain), I'm really surprised that I can only manage 13L/100Km with the honda.
Not impressed at all.

When the next service is due I'll get a wheel alignment hoping that makes some kind of difference. I still don't think it's normal to get that fuel consumption.

By the way, you mention your fuel consumption figures, are those from a Honda Odyssey as well?

Cheers,
Cecu
