Thanks to the Scangauge, I have now access to partial numbers on my drives.This morning commute, 55kms, I did 7.5l/100kms or 31.4mpg, mostly highways at 110km/h or 70 mph.
With the traffic jam on the way to home this afternoon, I won't probably be able to do that good and go back to the 8l/100kms range.
The tires are now at 42psi, doing a little experiment to see if I can gain mileage like that. Ride is a little bit noisier and harder... but it is always bumpy on quebec roads anyway 
That is ok with me, especially if there is a gain (tire wear should be better too), but my wife will be the ultimate judge, she has a more sensible butt sensor than me 
.
