Simon,
Thanks for the handy sheet.
BUT,
The more I look at consumption figures, the more convinced I become of the fact that fuel consumption is a dark science influenced by a large number of external factors.
I trust the sheet will eventually get some size and then one of you stats-gurus can come to some meaningfull numbers on the expected consumption of the various models and motors.
I know it's early days with this data sheet, but a number of 30% more fuel to feed the petrol Pajero is already surfacing.

As kid I always wanted to become an advocate. Now the advocate in me says that Marius' fuelly doesn't lie, but Marius didn't mention whether he lied to his fuelly

come to think of it my fuelly is showing pretty high at the moment. Higher than what I usually calculate myself at the pump.
I wonder what history fuelly uses to calculate.

Must confess, I have been tempted to gippo my fuelly entries 
. Damn, sometimes even I'm ashamed by my fuelly numbers 
. Problem is it forms part of my total record keeping, so petrol card and car kms and service record kms and dates and stuff must all gee out.
This 30% thing is a number I cooked up soon after going from DiD to V6, based on my own numbers. Thing is with the V6 consumption numbers, it is really fickle about how you use it. One "working trip" over the mountain in low range can ruin the global average for ever. That heavy old Jurgens can also do terrible things to my average.
If one had to park the V6 for the week and take it for a quiet cruise on Sundays, it will most probably give the DiD a good run for it's money. Cold start and idle while you close the garage and gates and stuff results in a "start average" of 50 - 60 L/100 at the end of the first street. By the time the motor is hot one is down to about 18 and then it slowly creaps down to the 14 - 16 bracket.

I assign a category to each tank, if it is more than 75% of one type of driving then it is assigned to that category, otherwise it gets popped into the combined cycle (which is about 80%)

Simon,
That is a good system and one I will have a look at implementing.
I think what I'm getting at is that two identical V6's (even driven by the same guy) can have vastly different averages purely as a result of their usage profile.

Attached is a (poor quality) pic taken with my cell while driving home from Jhb on Sunday.
It shows the average for the trip (over almost 4 hours) to be 12.4. The graph is built up out of little "packets", each representing the average for about 5 minutes of driving. The graph "grows" from right to left, so the first packet in Jhb sits on the far left. The double bar on the far right shows the current consumption.
The only reason I post this pic is to illustrate how fickle the V6 consumtion is to conditions and driver input. The run on the N4 in cruise mode is almost a straight line, from Badplaas through the mountains is a different story.
Thus; an honest and accurate global consumption figure for the V6 is almost impossible. The best one can do is to describe it as heavy on a good day and bloody heavy on a bad day.
