Fuel consumption

I get the following for my SD4 auto. City driving is around Canberra so its without too many traffic jams but a lot of roundabouts

Highway : 5.9 - 6.1L /100kms
City : 8.1L /100kms

I just did a return trip - Melbourne to Sydney - and average has dropped from 9.9 to 8.3... Hwy cruise must be very efficient.

My figure for a SD4 Auto after 8500km of mixed driving (countryside and some 600km trips on the highway) is now 10.8L/100km. This is since the car arrived until now without resetting.

I'm planning to bring it in 2 weeks from now for a (first) oil change and some small maintenance work prior the required 24000km oil change. I'll see if it makes a difference on fuel consumption.

I am using Road Trip Lite for iOS so quite easy for me to track costs vs performance give it a go!

As you can see, so far averaging just over 9L/100km of actual fuel usage (not relying on the dash reading). There was a lot of 40 degree days in the last tank of fuel but this didn't really impact consumption a whole lot.

Surprisingly I haven't topped the mileage I got out of the very first tank from the dealer!
