Hi All
Did do a site search first first , but besides coming up with over 3000 matches didn't really find the answer .
On my TDV6 I assumed a fuel tank size of about 87 l . Yesterday I filled up the V8 and it took 87 + l with the range indicating I still had approx 85 km on the tank . I know that the range indicator is notoriously inaccurate - but does this mean that the V8 has a bigger tank . Did try reading the manual as well but must have missed the page with fuel tank size on

According to the manual it has a 86 ltr fuel tank same as the diesel. I have filled up more I though about 90 ltrs. 87 ltrs is a normal fill-up. I'll check tommorow again as I have only 45 km to empty. The funny thing was in the last 5 km from the highway to my house it went from 68 km to 45 km.
I hope I can do the 4 km to the fuel station.  Roel

I have also experienced the same, and after fitting a 80 l aux tank filled it up (needle on 1/4) and stopped at 168 l  I still am not sure what he actual volume is it can take, which is not good. I carry a jerry can on long trips in case. Live Life, do Africa!

Roel, do you know sweaty palms are known to cause sticky steering wheel?

It seems to me that your views are based on the accuracy of the fuel bowsers.
Despite having standards and checks in Oz, I often found that I needed more fuel to fill when I used a "cheapo" SS, than when I used a major brand.
My eventual conclusion was that litres aren't litres in such cases.

Yup you could be onto something - drove the car until 0 km range , filled up last night and it only took 84 l this time . WTF ?

Wow, I knew kms arent kms and some brands are always on the same side of how they should count... but this is something different! Actually I would say this is theft!

Wiljo, I know that sweaty hands cause a sticky steering wheel. I found that after a sticky steering wheel problem the steering wheel beomes less sticky if the temperature comes down and now it isn't sticky anymore only rough.
I think I am ready for a new steering wheel.
The funny thing with the fuel is that with only 30 km left I could only get 77 ltrs in (BP). I think that has also to do what the slope is at the fuelling station. This time it was leaning to the right and a liitle with the nose up. I think that is the worst situation. Roel

Gents (& ladies), a good source at one of the fuel suppliers told me to fill up early mornings when it is cool.  Why do I hear you ask 
Apparently the density of the fuel changes substantially with change in temperature, typically in southern Africa by as much as 20 deg (or more) between morning and afternoon. I was told that they do not compensate for density changes, meaning that the early bird will get more BANG for his buck, sponserd by the afternoon sucker having less dense fuel.
One volume liter stays one, but with the variation apparently some gains can be had filling up early.
It will be interesting testing this theory, especially with petrol, as it is more volitile and may be influenced more Live Life, do Africa!

Well I don't know how fuel is stored in SA.
Here, the fuel is stored in underground tanks meaning that the fuel is always of more or less constant temperature. The density only goes down (volume goes up) after fuelling... which is why I've always instructed drivers to NEVER fill up 'till the rim in summer as the rising volume will cause the tank to run over... which happened on occasions so proven my point.
If fuel is not stored underground but is subject to changes in environment temperature, you are of course correct in what you say.

 Wiljo,
Point taken. Theory says it should stay at a constant 10 deg cel (apporoximate) depending on the depth of the tank.
I do have variations from fuel depot to depot though...
When one wonders into Africa it is a different story, being forced to buy fuel whenever / wherever one can. This includes above ground tanks (good days) or decanted containers (bad days).
Shall we call this theory tested & concluded?   Live Life, do Africa!
