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

Recently did a trip back to my parents (500km round trip) and found my fuel consumption seems to have improved significantly recently. I was travelling at a constant 110kph and a bit above for long sections and got about 10.75lt per 100km.

I have a six month old 110 and before I was more around the 12 to 13lt/100km.

I didnt use AC this time but I was also driving faster. Will be interesting to compare next drive.

You mentioned you drive in 5th or sixth
You can expect about 15-20% less economy in 5th compared to top

See this post with instantaneous fuel usage results from Ultragauge measurements comparing 5th or sixth gears http://www.aulro.com/afvb/2187098-post44.html

G'Day All,

Mine varies.
Around the city (so to speak as I live 35Km out of it) I usually get around 10.5 L/100Km. What needs to be taken into consideration is that there is a 10 km stretch at 110 km/h and it's all big hills for the 35Km trip to the train station.

I have cruise control, which is much thirstier than your foot will be. And I have a weight problem with my right foot anyway..... :-)

I often do a run down to Bunbury which about a 450km round trip (never bothered to measure it), and that is a pretty flat run. But, I am doing the majority of the trip at 110 Km/h. I generally get 10.6-10.8 L/100Km.

I took a run to Badgingarra, and back, the other week to pick up my kids. I had the aircon on, sat at 110 Km/h with the cruise control, it was raining, and there are lots of hills (not that you feel them much with cruise control). On that trip (approx 430 Km) I got 11.686 L/100Km. I was not too impressed..... But I did have the tyre pressure at 30 psi. [I have found the best pressure for my tyres, wear wise (most even), was 28psi. Best for stability, wear, and control 34psi. For control (emergency braking) anything above.]

Oh, I have a 2014 90', and have done 27K Km. No roof rack,but Snorkle and roo bar with spotties.


Cheers,

Phill.

I did Bridgetown,Nannup,Bingarup over the weekend and did 502km's and used 60ltres combined towing and touring. Pat

[QUOTE=DiscoMick;2344223]Driving Brisbane-Sydney over the last two days my 2.4 averaged 9.9 l/100kms over 850 kms beween fills of the 110 litre tank, so that's pretty good considering some of that was at 110 km/h. Better than my BIL's 80 series which is using 16-17 l/100kms.


On the trip home it averaged exactly 10 l/100kms up the Pacific Highway Sydney-Brisbane, which I thought was pretty good. The GG TR tyres were 36 front and 40 rear. I assume the Steinbauer chip improves the economy a bit.
Being a tightarse, I tend to be gentle on the throttle. In the wife's Yaris I drive so that most of the time the economy light is on.

I don't have the latest figures handy but as at January my Defender 110 2012 had travelled 32418km in the city, highway, cross country and towing (SIII LWT and trailer - 2600km).

For those km I had purchased 4074 litres of fuel at a cost of $6377.57. If my calculations are correct my 110 therefore averages out at 12.56L per 100km or 7.96km a litre.

Best ever was 9.94L per 100km crossing the Hay Plain and the worse ever was 18.25L per 100km, also crossing the Hay plain but towing the Lightweight. Around Canberra I sit just above 11L per 100km.


The defender is running on Wrangler MTRs, has a snorkel, an ARB bull bar and a 2m roof rack. That probably explains the fuel usage!

I drive a lot of local roads in Western Sydney, and often into the city mainly for work. A stint on the M7/M4 and then the Hell that is Parramatta Road all the way into Sydney Terminal, or through Newtown into Eveleigh. My 2013 90 still averages 8.6 Litres per 100kms. But as I have mentioned before, I do drive like a granny, bit like DiscoMick above, I'm a royal tightarse. But I am certain that I have saved thousands of dollars in fuel and wear and tear costs over my many years of driving. I have never killed a clutch, never had engine or gearbox problems and generally all it has cost me is leaving home a little earlier to be at work on time...

Having written all this, I had better go and touch some wood...

I think the MTRs are definitely the cause of some of the pain. By my guesstimate they add about 1l/100km, maybe more. I have a very light foot and yet can only get 10.5l/100km out of our 90 on average. Will try the Conti ATs next time around.
