Thread: Puma fuel economy

One of the primary reasons I installed my UltraGauge was to keep an eye on fuel consumption.

Getting real time feedback of 80L per 100km teaches you what not to do.

On the other hand, it is surprising how hard it can be driven with quite reasonable numbers.

Essentially, the 600 marks sort of average, which is what I was getting for the first 12K until they swapped out the ECU and injectors. Then I was getting around the 530 mark. Not good, but thought it was due to putting on the rack etc when I finally got it home.

So they've swapped out the injectors and fuel pump, and the ECU again at 80K, and now I'm getting 450. But I'll confirm that when I get back to Melb tomorrow :-/

Mark, I'd be looking into your figures I think. Are you running smaller diameter wheels at all?

After 16 years of defender ownership I've found road speed is everything with fuel economy.Both mine get better millage around town up to 80km/hr than they do at 110-120,defenders push alot of air which really hurts on fuel,I've travelled alot in the interior and the wind is a killer,I pushed into a headwind from north of Alice all the way to Port Augusta and struggled to get 400k's before the light came on if I even tried to go over 90,it's better to back off and suck it up than try to force your way forward.

Just driven up from Perth home 1500k,s heavily loaded pulling a 2 ton double axle trailer ( 1.5 ton) I recorded 12k,s to the litre. Generally from full, I get 62/64 litres of fuel burn (Puma 110) before the light comes on. As Pat indicated there is a big difference staying at 100k,s than 110, 90 is evan better in high winds but not always practicable. I have an Alive map, decat, centre pipe removed.

Am just about to leave, will let you know in the morning how we went, but my normal driving is to sit "on" the speed limit, so I will change nothing for the trip home.

Cheers for now.

My 2 bobs worth. Have 2010 110 Defender. Have watched consumption fairly closely since purchase. When completely stock was getting mid 9s to mid10s per 100 km.
Since then have added bulbar, roof rack and drawers and other various heavy stuff. This has affected economy by about 1 to 1.5 l/100.
About 9 months ago got BAS remap which has not had any noticeable affect on economy, but has improved drivability.
Have just returned from Flinders, Oodnadata, Simpson trip fully loaded. Over whole trip average was 11.5 l/100km. Best was 9.3 , worst was 12.4 across the desert. That was between 2 and 14 litres /100 better than fellow travellers.
My observation is that the moment you try to sit at 110 kph you had better start looking for a service station.
One last observation; I have spoken to a few people who run mud tyres and all terrains depending on their trips, and the common findings are that muddies cost 2to 3 l/100, especially if wider or over standard size

I struggle to get 450km out of the main tank these days - just goes to show what driving 3km to work and back does to the fuel economy

Cant imagine the Defender is enjoying that. Buy a bike!

We seem to be getting very low 10l/100km consistently.

10.16 was the last tank I think.

5500km in 3 months and I think every tank apart from the first one has been between 10.1 and 10.9 l/100

I am averaging 11s since I bought mine. Am running winch and LR roof rack and wrangler tyres. Never got under 10.
