Real life fuel consumption

[Cuppa]

We have recorded our fuel consumption for several years travelling a wide variety of terrain. Most but not all towing our Tvan. All up weight of car + Tvan fully loaded is around the 5tonne mark, which obviously goes down as supplies, fuel & water get used. 265/75R16 tyres

Best was a fraction over 12L/100. Worst was 20.5 L/100. Average over two periods comprising a total of around 5 years (Stuffed up with the app & had to start from scratch again) showed almost identical averages - First two years & second 3 Years - 15.6L /100 within 0.1 litre. I have a fairly light right foot - often happy to poodle along at 80 or a fair bit slower on tracks. It makes a difference! If we were towing on the CSR I would be allowing for 25L/100. If car only probably 20 or 21.

Our fuel tanks hold 180 litres, (95 & 85) would normally get us well over 1000kms, but for the Canning I'd be carrying 4 jerries in the car too & feel fairly confident that'd give us a reasonable safety margin.

I think we've decided to leave the Canning until we have a truck based camper. Towing, although do-able sounds like hard work & less enjoyable. Without the Tvan we'd be carrying a tent & I think we're already too decrepit to consider that any more!
