Thread: Spinoff question: Your fuel consumption per 100km

Fifi, off subject but if you have 2 months to go and plan to keep the D3, then the Allianz extended warranty might be worth considering. See the threads on this in the D3 forum.

I got mine through Luke at SCLR.

Cheers.

Found my sums...... This was while I was in Sydney, so I noticed near enough 3l/100km improvement in fuel consumption from 91 to 95 (around town) between 95 and 98 it only improved by 0.2l/100km.

In general it is 13 - 14 ltrs per hundred with short city driving and 11 on highway.

D3 TDV6 HSE with BAS Remap.

It is worth noting that all the figures I am quoting (and I suspect most others in the thread) are as per the computer. Fifi, if you are actually calculating your fuel consumption your quoted figures may not be so bad. The computer on the D3 has a reputation for being optimistic and under estimating fuel consumption..... If you are quoting the computer figures, it could be that you just have an accurate and honest computer.....

The variation between displayed and actual for TOD has varied by as much as about .8 ltrs per hundred to as little as .2 ltrs per hundred.
TOD is always optimistic but sometimes the difference is very minimal.

Yeah, I'm quoting the onboard computer.

WhiteD3, I didn't know about that extended warantee. Thanks, will go see if I can find the threads.

My figures for the Series III were not from the computer.

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.

OK, figures:

After loss of spreadsheet, here's figures for overall average only:

Distance L/100km MPG KM/L
7749.7km 10.29 27.45 9.71

For our Tassie trip:

Distance L/100km MPG KM/L
3777.1 10.32 27.36 9.68

Most times the OBC would say between 8.8l/100km and 9.9l/100km. Car is not accurate at all, but still VERY VERY good for a 2.5t vehicle.

A big factor is what defines "suburban" conditions. I know that when we moved from Sydney to Perth our average speed (as per computer on another car) increased from 21km/hr to 32km/hr. I would have to think that a bit more steady suburban driving speeds will lower the consumption rate. Oddly, the V8 tends to have slightly lower consumption than the V6 petrol, but the savings would never pay for the difference in cost. The V8 is a pretty highly tuned motor, so the improvement on 98 RON fuel may be better than the V6.

The 50l/100km I quoted for the beach is probably the highest possible figure for the V8. It was a sand lesson for my (then) 21 yr old daughter. She was deliberately driving on the soft sand high up on the beach (she replied, "Because it's more fun" ) and the sand was above the axles, AC was on full (this was WA in January) the radiator fan was on full roar - noiser than the engine, and the engine temperature was trying to drift into the "high" zone. It was indeed fun and I think the engine and chassis were finally being used at their design capacities for once. I'm looking forward to replicating this test with the 3.0 TDi next summer.

bugger, cant cut and paste from excel and it wont accept spaces or anything else to format.

going across

TDV6 HSE. basically average is between 11.96 to 14.3 depending on how slow the driving is.
