Thread: 2.2 Puma Defender Fuel Economy

My 2.2 110, gets around the 12-12.5 per 100 on open road, much worse than LRA will tell you (9 on the open road). But agree that dropping it to 100 rather than 110 definately helps..or else just pop in behind a truck!! Havent used it around town much, so can't comment what difference that would make. But I would also love to hear from anyone who has any ideas on how to drop this down at all.

2012 2.2 Puma 130 HCPU got 11.5l/100km when it was new.
Since adding bullbar, ally canopy and roofrack it still gets 11.5/100. All rural driving- highway and bushtrack

However the speedo reads high (compared to GPS) so I presume the odo is also high. So my calculations may be about 6% low making it really 12.2/100

From this thread, I get the message that either the 2.2 is not as economic as the 2.4, or I get freakishly good economy!

I have been watching my economy over the last few weeks, and have seen as good as 9.1l per 100k's.(as high as 10.5l/100)

that's in an empty 110 wagon, unladen, easy (early morning) city traffic averaging between 200 - 300 k's per week !

Must be the superb aerodynamics (I dont have a roof rack!)

My 2.4 is about the same as 4ranges, 9.4l per 100 in the city and 10.5 on the Hwy. No roof rack and she is empty most of the time. Better than the MY08 hilux I had

Actually have a look at how the fuel consumption numbers are devised ... the extra-urban cycle is not what I'd call a highway or freeway run ...

All the PUMA speedo's indicate faster then their actual road speed, so anybody calculating their fuel economy from their odometer....the figures are flawed in favor of better fuel consumption.

The variations are all in the right foot of the driver - I thought my 2.4 was thirsty (12.5-13.5l/100k) until I followed a similarly equipped 110 (mud tyres, roof rack, bullbar, cargo drawers, etc) and discovered that mine can easily return 9l/100k.

Unfortunately I find that maintaining that type of economy for any distance would be very expensive (cos' I'd deliberately drive the truck into a tree to make the misery stop). Consequently I've decided to fit a chip, bigger intercooler, bigger tyres, more lift, another 150 liters of fuel capacity and a new winch in an attempt to get better economy...

For my MY12 110 Wagon I got:
Odometer (km) L/100 km
1198 10.8837
1683 10.5588
2222 10.4638
2837 10.8407
3222 13.774
5851 10.833
6711 10.9907


The 13.774 was from a day of winching with the 110 idling for long periods of time.
All in all pretty good economy. The small increase over time is probably due to a weight increase from bullbar, winch, drawer etc.
