Thread: Disco 4 Long Range Tank

Since I changed the transmission oil and filter a month ago, it is like my gasoline tank is a hundred kilometres bigger - maybe 200 for paved highway. 2005 gasoline 4.4l V8 LR3 HSE

I used to get about 16.5 litres / 100 km around town; now it is more like 15. On the highway, previously maybe also 15 litres / 100 km on a good clear highway; today with the air conditioning on, sunny, OAT about 21C, speeds 120 kph I got a bit better than 12 litres / 100 km measured.

I have never seen fuel consumption as low as that in the last couple of years so I conclude my tranny must have been slipping or something and the oil and filter change improved something. Acceleration is also better.

For me, this was way cheaper than a bigger fuel tank and my spare still hangs underneath.

Any photos of these auxillary tanks fitted, I wouldn't mind seeing how they look for clearence, do they hang lower than the spare wheel

Be aware that having a fuel tank as the point of contact with regard to departure angles doesn't have the same roadworthiness as a spare wheel, even though the tank might not be as low.

Great to have the extra capacity.
You just have to be aware of the tank. Clearance is not compromised and it depends if you are out there looking for trouble.
If so - buy a Defender.

I was concerned about the fuel tank being the point of contact too. But this forum did not showed any adverse happenings due to the tank.

Also the original tank hangs down to the lower edge of the chassis, and there is probably more chance of knocking this than the Aux tank.

I'm mindful of the occasions when I've slid the rear of my RRC and D2s down rock ledges on the towbar support bars that protected the fuel tank and would be happier to see something similar on the D3/4. However being able to select more height on the D3/4 lessens the exposure, along with less overhang anyway. I'd like to fit a RWC to get the spare out from under the vehicle and if I did, I'd probably later fit a LR tank too.
