| 1406850 | 2015-08-17 06:29:00 | Is there a reason for vehicle fuel consumption figures being given as litres per 100kms? In old terms figure were miles per gallon. Why are we not using Kilometres per litre? I am thinking of my old van that did 8kms per litre. If I run out of fuel and put in 5 litres from a can then it is easy to work out that I should now be able to do 40kms before running out again. Easy calculation but not so easy if I know my van does 12.5 litres per 100 kms. |

| 1406851 | 2015-08-17 06:41:00 | I agree what I do is do a consumption test in miles per gallon it means something to me. Did one on my hose truck was 14mpg, thought bugger that cant be right did another 2 they were 13 point something mpg. Just the weight of everything I guess and the drag because it was a luton body. House bus is 15mpg strange because its treble the weight of the hose truck and engine is twice the size but it does have more gears 24 in fact 6 speed with splitter and 2 speed eaton diff. |

| 1406852 | 2015-08-17 06:43:00 | My 2008 Corolla requires only 5.8 litres to do 100 km (official figure) It's a matter of efficiency. The less fuel it takes to do 100 km the better. Some (hybrids) are less than 4 What are these olden times you refer to.... ;) |

| 1406853 | 2015-08-17 07:00:00 | Kilometres per litre makes more sense to me than litres per 100km. It's "how far can I go on a tank" rather than "I need to go 100km, how much fuel do I need". Of course, miles per gallon only makes sense to me on Top Gear ;) |

| 1406854 | 2015-08-17 07:04:00 | It's likely just because most places that state fuel economy decided to do it that way, probably following car manufacturers who made that the default on most built in trip computer displays. My cars trip computer shows km/litre (2002 camry) and my work car shows litres/100km (2011 corolla). I guess Toyota changed their minds at some point. Just adjust your driving habits until you get to 10 litres/km, that way it's the same with both measurements and you don't have to worry. |

I guess Toyota changed their minds at some point.My 2007 Swift shows kilometres per litre, but can show in any of the three mentioned units. Not sure if that's the Suzuki default or the previous owner's choice though. | pcuser42 (130) | ||
| 1406857 | 2015-08-17 08:33:00 | Maybe it's economics vs consumption. Most personal drivers in NZ perhaps only interested in km/l. But maybe truckles- running already economically may find l/100 km more meaningful for calculating/optimizing road user costs and for general trend stats. Many travelers in the US/Canada travel vast distances - interstate, and perhaps reference liter costs per travel distance of 100 km. One USA Honda forum I'm on, members were often travelling > 1500 k through a few states - then back. They hardly mentioned costs per gallon, but more the nearest localities or counties or state lines. Never mind consumption costs. | kahawai chaser (3545) | ||

They hardly mentioned costs per gallon, but more the nearest localities or counties or state lines . Slightly OT, a Canuck friend was driving from LA to Toronto in a Honda Civic, circa 1974 . In the middle of the night, almost out of gas (aka petrol) in a remote midwestern village, the local service service station refused to sell him gas because he was driving a Japanese car . An appeal to the Sheriff was partially successful - the station was forced to sell my friend gas - but only enough to get him to the next township . :groan: |

| 1406859 | 2015-08-17 21:53:00 | Should go back to measuring it in how many "Cheery-pip ol' chaps" are received per 317 handspans or something, perhaps. Litres/100km is a simple, and broadly averaged rating that is relatively simple to test in a consistent manner between vehicles under controlled conditions. km/litre is more suited to establishing remaining range based on a known fuel quantity, as long as the km/litre value used is averaged across a sufficiently broad sample range, and it fluctuates more significantly (relatively) over short periods. | inphinity (7274) | ||
