Thread: Fuel Consumption

This was my first big drive in my 2011 FL2 SD4 HSE after picking it up last week ( 15000 km),didn't manage to get what they quote in the owners manual 5.7/ 100km but I'm happy with the 6.8/100km I got coming back on the New England HWY from Byron to Newcastle full of camping gear with back seats folded down. Love the torque on the SD4 the engine bearly revs over 18000 rpm , as much as I love the 6 speed auto I find using the command shift I can take advantage of the torque of the engine in the hilly and windy roads.makes it more fun to drive too.

I have just completed a trip of about 7000ks that included about 80% towing an off road camper, the rest made up of highway,city and off road .Towing speed was generaly between 100 and 110 mostly on the flat straight Stuart highway but with some good head winds . At the end of the trip the trip computer showed 10.5 ltr/100k average ,I suspect it is a bit higher but not much.Very happy with this as my popular 3ltr work fwd does not get that empty doing highway work .

Noted after 10,000kms after the first 10,000km of mixed driving, my 2011 SD4 HSE (bought new) has returned: 10-20,000 = 8.2 l/100; 20-30,000 = 7.9 l/100; 30-40,000 = 7.6 l/100, and so far 40-45,000 is 7.5 l/100 and running.

Looks like it's almost run in, then...

I have a brand new , well 1800 ks 2013 diesel which averages 6.9 litres per 100 on the highway at 110 ks using cruise, 2up with a little gear on board.
I am super impressed with this as cruise always used substantially more more fuel on the old Commodore.
Cant imagine getting any better even when run in. Is it just me or are these are real nice drive particularity on the highway.

Hi, all, at 37,000km I'm still not getting the less than 8L/100km which I envy in other post-er-s. I live in hope. Notably, my dash-computer cheerfully informs me that I'm now averaging 8.2L/100km. The litres I pay for calculates out at over 9L/100km. It has improved slowly as it's been run in.

My 2008 Td4 (86,000km on the clock) manages around the 7.2l/100km on a long journey with cruise control between 100-110. Around town it sits on the mid to high 8's and doesnt head much above that unless its real start stop driving.

Drove to Canberra from Sydney and back Fuel economy 6.6ltr, pretty happy with that.

Cheers

Indicated or calculated?
