Title: Fuel consumption
Post by: George23 on November 24, 2020, 18:11:31: Hello!
I just bought a 2016 GD 1.6 diesel two weeks ago.
This is the first diesel car that I own.
I drove about 500 km and I noticed that the consumption is somewhere around 7l/100km. I expected it to be lower.
I mostly drove on countryroads out of the city.
I really tried to save as much fuel as I can but I still cannot achieve a better consumption.
Is this consumption normal? Am I doing something wrong?

Have a read of the pinned topic by Aussie Keith - may make some sense :)

Post by: josh1990 on November 25, 2020, 20:33:42: My 2015 GD Tourer always gets 5.8L/100km as soon as we get out of town. Around town is in the high 7's low 8's - which doesn't bother me. My XR6 ute gets around 8L/100km out of town and 18/19 around town (geared for the highway).

Post by: George23 on November 25, 2020, 20:51:22: Maybe the consumption is high because I am not used to diesel. How many revs should I have when changing the gears to drive more economical? Changing the gears at lower revs will harm the DPF?

Post by: josh1990 on November 25, 2020, 23:33:44: Keep in mind we have no DPF (in earlier diesel i30) in Australia and that will use extra fuel as well.

i typically get around <7l per 100klm around town and i've had as low as 4.8l out on the hwy at 100kph on cruise control. :happydance:

tried pushing the reset on your odometer to 0[average mode] after each tankful...or when you want to do an economy check?

you also neeed to stick the peddle to the metal on occasion to stop carbon build up [injectors turbo exhaust] - this doesn't effect my economy figures. in fact she loves it! :Drive:

3.5L/100km on the display as I pulled into my garage.
