Hello all,
As many 'overlanders' seem to fit in either additional fuel tanks, or carry several jerry cans, it leads me to the question of Land Rover Fuel consuption, and tank range.

I know nothing about LR consumption or size of fuel tanks, presume, 88 / 90 / 108 / 110 / Disco etc, and 130, if it is used as overland vehicle, they all carry different volumes of diesel / petrol. yes ?

So, to make things easy, let's just work on 'unloaded weight' no kit weighing the vehicles down.

Which vehicle gets best mpg, which gets worse mpg
Which has longest standard tank range, which has shortest tank range.

110 tdi or TD5 with twin tanks. 90 has a 50 ltr tank.
 
we are running a 110 full kitted out with a standard tank 72 lts and 2 x 20 lts jerry cans and at the moment it is on average returning a very nice 9.3 kilometer per liter.
 
depends if your driving on sealed or unsealed routes vette.

Red, the TD5 90 tank is 60L ( I thought).

Standard 90 tank can take 50L. I will be running both on my 90 shortly.

I get 26-27 mpg here in the UK on motorways etc. drops to 25-26 with RTT and loaded. Unsealed routes abroad 24-25 mpg.

I worked out using both tanks I should get a 6-700 mile range out of my 90 between fuel stops.

Hi Vette,

Studied this very point over the last couple of weeks; first of all depends where your going.

My 110 will probably do 6/7 miles per litre, but with a rack/roof tent/boxes on 4/5 miles a litre. When loaded about 3 tonnes about 4 miles a litre.

With a standard 80L (approx) rear tank, there are few options, as for fitting 'pod' type tanks outside the chassis this is illegal, apparently, in Western Europe.

Options; fit a long range rear tank about 120L and a 45/50/60 90 def tank, at an £££ cost, or fitting a purpose 100L tank (approx) on the floor in front of the middle seats, or carriers.

Personally, I'm looking at carriers; you can fit 3 down each side of the rear windows, + 4 on the roof + 2 at the back (space between rear door and mobile storage drawer helps to secure these) + a couple more or so on the floor in front of the middle seats.

Why so much fuel, and why carriers? (I'm going on a 4 week hop to Morocco (solo) or to Libya with some friends, this is what everyone has said for Libya)

In desert I need to be carrying enough for about 1000miles (approx) at around 3 miles per litre; 14 carriers (4 roof/6 sides/2 rear/2middle) + 80L tank = 360L.

Why so much, if you go off piste for a few days even in a group, your going to drink fuel at a greater rate, and secondly, if you get stuck, carriers can be removed from the vehicle, they by making it lighter to recover.

Cheers, Mark

Hello Mark,
Thats very informative.
So fully loaded, I should expect some thing like only 2/3 of my normal fuel consumption.
I am also in a phase where I don't know if to fit a single additional tank, or to carry separate 20 liter jerry cans.
I suppose there are pro's and con's of both methods, which just makes the selection that much more difficult.
I don't have the option of carrying additional jerry cans along the side of the vehicle, so any additional jerry cans would have to go up top on the roof rack.
I have a very convenient place on my LC where the spare wheel could alternatively go, that is, (as mine is on the back door) between the chassis rails at the rear.
But by putting a 'sub-tank' there, it hammers the rear springs, as all the weight is behind the back axle.
I would be looking to carry an additional 100 litres, to my standard 90 liters.
On sealed roads, this would give me about 1200 miles, 950 miles on gravel, and say, 800 'off road'

Cape Town is calling loud and clear these days !

I think you need to work out the longest distance between fueling points and plan on how long you think you will spend in the bush. 1Life, Libya may require vast amounts of fuel (speak to Chris Scott on the Hubb) but Morocco is fine with a standard 110 tank. I took a standard 90 with 2 jerry cans and only once needed to use 1/2 a can.

Vette, I would try to avoid putting cans on the roof as im sure you have read elsewhere and still look at upgrading the original LC tank and maybe an additional one somewhere. Can you not find one designed to fit further forward of the rear axle? Again try the LC section on the Hubb. A chap we met in Morocco (jean) also on the hubb traveled from SA to Europe and back (east and west coast) with a LC and trailer. Im sure he managed fine for the entirety of the trip. He also likes a fair bit of off-road!

Looking forward to using my twin tanked 90 :D

Its cheaper easier and in my mind better to run OM equipment on an expedition vehicle. You can get the TD5 rear tank set-up for £200-£250.

3 tanks is not silly. You could install the underseat tanks on both sides of the 90 along with the TD5 rear. You would just need to find a new home for the batteries.

Yes That makes sense, don't think I want to move the batteries though, so maybe just the one underseat tank.

Would you mind saying how you plumbed in your TD5 Tank ?
 
A Y piece filler on the original and a 12v fuel transfer pump. Its a very simple solution which can hardly go wrong. I will hopefully be doing a full write up for LZ when I finally get a few days to go ahead with it.

Thanks Griff, a writeup would be cool :D

Hi,

Yes I was talking Libya re: 1000 miles @ 3L, Morocco I'll need a lot less, depending on what my plans are.

I've looked at extra tanks; apart from the 90 tank under the seat, you can get 50L pods for each underside of the chassis, or/and a 100L on the floor in front of the middle seats and/or rear quarter 45L tanks. All great ideas, and having just an extra 45L tank useful just day to day around UK. All of these cost £££.

So I'll probably go for extra carriers, it just allows me to use as many or as little as I need, shift weight, and if I get some bad fuel, then I can easily get rid of it. I've had 4 full jcans on the roof and went off-roading, it didn't seem to be too much problem, though I'm aware of the 150kg rack limit for a 110.

Great thread Vette. Cheers, Mark

Hello Griffdowg,
I have since found out that a diesel tank of a SWB LC Colorado, (65 liters) is mounded at the very rear, up between the chassis rails, (where a spare is some times mounted):)
So I will see if I can spot one at a 'scrappy' and measure it up.
Can only cost about £50.00 with the fill pipes, sender, and under tank securing straps.:rolleyes:

So Griff,
Was your 'Y' piece filling OK ?
Easy enough ?
Keep it simple works well with me.:D

I drive in january-february from Romania to Bamako, Mali, with an extra loaded 200 Tdi Disco 1, with standard fuell tank (80 liter) and 2 extra jerry can. I realy don't use the jerrycans. Fuel consumtion 10.3 litr/100 km
 
we are getting in our fully loaded 110 about the same 10 lys to 100 kilometers but thats on good tarmac with the tracking all out, will be getting it checked soon so would expect a little more.
