Fuel consumption in my car is very different to before I got my fuel card back... I miss the days of under 10l/100km.
 
My main car for a while was a Toyota FJ Cruiser,don't think that had a fuel computer (I don't do instruction manuals) but I know it sucked juice!
Now I drive a Land Rover product,I'm pretty sure that it has a fuel computer but I'm shit scared to play with it in case in goes wrong:):)
 
My 2.8l Sahara did 10l/100kms in traffic and 8l/100 open road. In 4 low it did 12l/100kms.
My 3.6 Rubicon did 12/100kms irrespective of conditions. In 4 low it did 18l/100kms.

Currently doing 3.1 to 3.9l/100kms when driving like a granny and 8l/100kms when in sport mode. Averaging out to about 6l/100kms.

Impressive figures for such big, heavy things!

They were the 2012 and 2013 models.
The new v6 pentastar engine was 25% more fuel efficient that it's predecessors.
Still heavy as I was paying over 6k a month on fuel. This is one of the reasons I sold them and I do miss them terribly.
 
According to my calculations, my etios hatchback is doing 7l /100km. That's too much for a hatvhatch don't u think ??
 
I concur. What car in this day and age (apart from a Datsun Dead) doesn't have a trip computer?

They are not very accurate and work by average. I compared @Hooked 's method to what the car's computer told me and the computer was quite far off. I have a 2007 Mercedes C class. So I don't really trust the computers. I like to do it manually. I trust myself.

That's odd. Trip computers in all my cars (even all the Frenchies) have been pretty much bang on.
 
Do not trust a VW trip computer! It has a little sensor that tells it when you are looking at consumption and shuts down two cylinders during that time.

Nonsense asside, i do not go by what the tc tells me, most are optimistic and programmed to give good news. Neither my current vehicles have them and they are not missed.

Fill up and divide the km’s traveled by the litres put in tells you k’s per litre and thats all you need to know.

The Mazord dc gets ten to the litre no matter what and the Jimny tries to beat it, almost getting there at eleven to the liter. When driving like a grownup it is capable of almost fifteen though.
