Thread: 2012 Defender puma 2.2 fuel consumption 13.5l/100??

iI wonder if it could be something like a binding hand brake, or a dodgy wheel bearing. Not sure how to check this safely with the nature of the hand break, maybe lists of chokes.


or fuel filter?
Bloody auto correct

Also note the tanks are not as per the "showroom" specs. In a 90 for example it is actually a 56l tank I think and not 60, can make quite a difference to your calcs.

As far as an accurate figure is concerned, "300k on three quarters of a tank", is not the way I'd be calculating.
I'd fill up the tank, take the odo reading, use up half three quarters of a tank etc, then take odo reading again, & work out consumption from there.
Gracie is the first Defender we've owned & unlike other cars, we often find that we get the same, or even worse consumption on a trip maintaining say 100kph, because the Defender is "Hard to push through the air". This is unlike other vehicles we've owned where invariably country cruising obtains much better economy.

These figures correspond to around 27 and 25.5 mpg

Thanks for the replies everyone, I'm pretty sure it was dodgy fuel I've had a bad batch from this place before in my golf but I filled up with BP and it seems to have settled down a bit and not smoking anywhere near as much as it was.

I've found mine likes Caltex diesel,road speed and wind,wind is the economy killer with deefers.With diesel engines don't pander them,drive the suckers,remember that diesels use heat and pressure to burn the fuel,if you drive like Miss Daisy you'll just carbon it up. Pat

How fast do you drive? When I first got my 2012 2.2 90 I used to drive the Hume often between Syd and Melb. Going over 110km/ph often saw 15l/100km. Defenders don't like to go over 100km/ph. I used to get better fuel economy around town. Bit different in a V8 Discovery. I get 11l/100km on the highway and around 18l/100km around town.

Another word of warning. When the fuel light and tone comes on, fill up. You will be lucky to go another 40kms. Trust me on this.

Most of my driving is country road sort of stuff on the back way to work, usually sit on between 80-90km/h
