Thread: Fuel tank capacity?

Fair enough too, Craig - but having 13 - 15 litres effectively unavailable is more than I'd consider necessary to avoid any sludge at the bottom. It's another 100 - 150 km of possible range, and so many times I've been in the same situation Graeme mentioned - forced to fill up "early" due to the doubt around how much fuel is actually left. It's enough of a pain to be working around an 80 litre tank (dare I compare this with many Toy-trucks and 150 litres ++?) without having to surrender to sub-70 litre capacity!

Garry - interested that you regularly put 80 litres in your RRS: I wonder if there is some difference between the RR and the D4? Or do you do the jiggle-slow trickle-jiggle-slow trickle thing to squeeze the last 10 litres in?

Despite good fuel filters etc now a days, I still stick with my method.

Why would you pick up any sediment only when fuel is low - the pickup is near the lowest point in the tank so if there is any sediment you will be sucking it in anyway - irrespective of the fuel level - an old wives tale for car fuel tanks.

Different is filling from drums etc where you might be able to raise the pickup point.

Around town I drive down to the light then fill at the next opportunity. Yesterday the light came on at 750km with 80km left. I drove the 15km home and still have 80km left (was on 80kph dual lane). I will fill tomorrow and expect to put in about 78 - 80 litres.

The tank is the same as the D3 and I fill to the click and then a little more until it starts to spit back but not until I can see the fuel coming back up.

When I fill I will let you know the stats.

Thanks Garry - that is the same fill method I use, other than I push it a bit further, until I can see fuel bubbling up the spout. So - something is a bit weird here. I'm going to go fill up today, and do Sniegy's thing of trickle filling after the click and see what I can squeeze in.

Tried trickle filling my D4 (35k dist to empty, yellow light and took 71 lts) but only got a couple of trickles after the click..On the other hand drove my 08 RRS with 88ks to empty and yellow light on and managed to get 75 litres into it today when I filled up.. I think the tank on RRS is slightly smaller than D3/D4. So I would say that LR have changed something.. Asked my dealer service manager bout it and he new nothing.. He said he would ask LR for me but I don't expect to hear from him. But you never know.

Went to the pump with 135 km to go - figured at worst this should equate to say 15 litres (at around 11 l/100km), which meant I should be able to put around 68 litres in. Pump clicked off at 59.2 litres - about what I'd expected, given the distance I'd traveled and my likely consumption. Tried trickling more in, stopping, bumping and wobbling car - trickled until it was literally right up the spout to the neck - 61.8 litres.

Which means I should have had 22 litres left (84 - 62), which means at my average real consumption of a tick over 11/100 km I should have had at least 200 km range still available. Given that there appears little to be gained by the trickle feed (other than a spill down the side) I am now reckoning there is at around 100 km beyond the 0 to go mark - something similar to what Craig reported being told by his local dealers. Question is - am I brave enough to put it to the test? It would be great to know just what the reality of this is...

Because the concentration of rubbish increases as the volume of fuel gets smaller and the rubbish is confined to the well where it might not be if there was more fuel.

Ran my RRS down to '0km' range today and did around 5 extra km before filling. Took 79.8 ltrs of diesel.

If filling, I tend to slow down to around half pressure when around 20 ltrs to go, just to reduce foaming. Then trickle the last couple of ltrs in.
