Thread: Spinoff question: Your fuel consumption per 100km

I just came back from a trip to Lake Eyre. Melbourne to Hawker to Farrina Ruins to Andamooka to William Creek (for the 2 hour fly-over), then Halligan Bay, Maree, across the Cooper, Mungerannie and then back to Melbourne.
We did 4090 klms and a total usage of 11.5 l/100 on diesel - with a mixture of road, a bit of sand and many dirt roads with a loaded cargo area + roofrack with spare tyre and 40 litres of water/fuel.
Tyre pressures down to 28 psi on dirt, 40 on bitumen.

The best ever economy I have recorded was 7.3 l/100 on another highway trip with my learner daughter driving.
Cruising at 90 klm seems to give the best econony, but that makes it a slow trip. I would rather cruise at the speed limit and use more fuel.
I have also noticed that a strong headwind wind can make up to 3 l/100 difference.

I often wonder how many people (with or without computers) bother to correct for odometer error. My Series III used to travel 107 km for every 100 km indicated. The Defender does 97 km for every 100 km indicated. People sometimes make a correction when they have strange tyres fitted, but even with standard tyres, most odometers seem to be a bit optimistic.

VNX wouldn't that mean your speedo is out too then? How would you know if you were travelling at the speed limit?

Trobbo - that is an incredible figure! Are you driving a diesel?

Our best seems to be around 11 - 12l/100kms on the highway (with my husband driving, I might add ). But even then, it is hard to hold it on that for long. And that is with newly fitted Pirrelli Scorpions. School pickups and peak hour traffic will still drive mine up around 18 - 19l/100km.

Hi Fifi, yes tdv6 hse. When I saw those figures coming up the rear view mirror sure did get a workout looking for a big mack truck.
Usually I sit around 13 or 14 ltrs per hundred with city driving.

Hi
I have a D3 S 4L petrol. Fuel consumption around the city is awful. However, just got back from a 2,500km trip and achieved just over 12L/100km.

Hi Fifi, I have the D4 3.0Lt Diesel and average 10.5 Lt per hundred with a mixture of driving (mainly around town).
On a trip, I have achieved as low as 8.0 Lt per 100.
Cheers, Craig

I have 54531km at an average of 11.08 l/100km on a 2008 TDV6. Most of my driving is to and from work about 20 km of freeway (or car park - its the M4 in Sydney ) and about 10 km of suburban road each way.
Cheers
Mike

You guys with TDV6 D3's should be really happy with your fuel consumption figures.

The best my auto Td5 D2a has done is 9L/100 .... worst (stockton beach) was 18L/100 ... around town (not city, coastal town) is about 11-13L/100 depending, and my long term average (over the last 18months - on/offroad combined) is 11.8L/100.

You guys are getting around the same or better, with an extra 25% worth of vehicle to drag around. Impressive!

... and I also get worse figures when SWMBO is driving

Wow! The difference diesel makes is huge, isn't it? Has anyone done a comparison on the cost benefit of diesel versus petrol engine? It would be interesting to know how long it takes the petrol savings the diesel makes to pay for the addition $10,000 or whatever it cost. I think I've heard the diesel engine lasts longer too, is that right? And do they drive differently to the petrol version?

And what are us girlies doing that make our cars burn less efficiently? Is it because we all do the school and grocery runs so there's lots of idling around carparks while you boys do the highway driving? Or do we really drive differently? That is my next question .
