What do you get on a full tank ??

[revjames]

Just took the fan off so we will se if what has been said on here is true. Got it in the boot plus got air con so I could use those fans I guess

This is my point. A/C models have 2 big leccy fans on the front of ther rad, If you short the 2 wires on the sw on the thermostat housing they will come on. I think the setting on that switch is a bit high as I have only ever heard them come on when the engine was almost at meltdown with the head gasket fault. A switch on the dash wired in paralell would be handy. I intend to give it a go (keeping the VCF in the boot just in case

Is that the connection at the top of the housing connected to the aircon loom?

I was hoping that that would be quite a low setting so I could use it like you say.

If not looks like a switch and a realy for the time being.


I have drove about 7 miles with it so far all seems well. See how it copes with the drive to work in the morning (15miles)

 

[revjames]

I think its a high setting so its a kind of back up. I wonder if you can get a lower rated one?

Disco 2 TD5 (Fathers)

Regularly obtains 450 - 500 miles per tank, the latter with more motorway miles at 70mph. I must add that when we fill the car we continue to fill after the first click (and wait for all the froth to subside). Takes about two mins and you can squeeze quite a few extra litres in. I stop when fuel is visible in the filler neck.

Last time I borrowed I filled from light and got £94 in at 104.9ppl.

Are you guys filling to the top or to the first time the pump stops??

Also notice worse economy from sainsubury's (to name one) city diesel. If we use Bp regular diesel (not ultimate) then we always hit the 450 miles minimum.

Regards,

Steve

Yeah we fill it right to the top just before it comes out !!

and count when the light comes on permanently !!

I know with mine I can get 80 miles out of it when the light comes on !!!

Just keep an eye on the temp mine only goes above the halfway mark when I cane it

The temp gauge seems to be staying in the same place as when the fan was connected, just below half way.

Its now done 35miles since removal.

Traffic jams, summer, then you'llneed leccy fans

Traffic jams, summer, then you'll need leccy fans

Certainly long hot traffic jams are a challenge to the cooling system, that's why I keep the fan with me, but I have never needed it.

I accept that I have some responsibility to monitor the situation and re-install the fan if needs be. Fortunately it only takes 30 secs.

Yes your right on the diesel so you cant set it ( you can adjust the amount of boost on it though)
but you can on the petrol.

Please explain .... I really REALLY want to know how to SET a turbo in turbocharged petrol engined car.

Please ...

I am going to be looking at getting rid of the condeser for the air (dont work anyway plus you need to mod it to run on the new gas) and put the air con fans directly on the rad.

As a matter of interest my TD5 did a 420 mile trip in the summer using 9½ gallons of fuel in then process.

The tank takes nearly 95 litres ....almost 20 gallons .....

I would nearly be prepared to bet that I could drive my TD5 for 800 miles on one tank of diesel. It would be a long slow cruise, but I am sure I could do it.

How did you manage to get 44mpg out of it????

 

[oil dripper]

used to get 720 miles outta me old RR with a 200tdi fitted enuff for belguim un back with a trickle left over

 

[thebiglad]

We get well over 40mpg on a run out of our 16yr old Tdi 200 - you just need to drive them properly and stay under 65mph.

Ok then how do you drive em 'proper' ????

That's easy to say, harder to do.

1. Don't over rev, change up gears at about 2500rpm;

2. Always keep looking ahead so that you can anticipate changes in road conditions and alter your speed accordingly eg when on the open road, you see in the distance an obstruction, slow down now, to give time for the obstruction to move. Slow down in anticipation of a reducing speed limit. Take your foot of the gas sooner when coming to a roundadbout.

Reading the road and anticipation is an important part of good mpg;

3. Don't go over 60mph - the aerodynamics of 4x4's are awful and cause increasing drag as the speed rises. But it's not linear ie 10% increase in speed, 10% increase in drag, it's exponential (I think that's the right name??!!), 10% speed increase - 10% drag increase, 20% speed increase - 40% drag increase!!

So, cruising speed has an enormous effect on mpg.

4. Don't expect car-like performance. These vehicles weigh roughly 2000kgs, with engines that provide about 55-60 bhp (for diesels) at the road wheels (loads of power loss through the transmission) whereas an average Modeo 2 litr Tdci gives about 100bhp at the wheels and weighs about (depending on model) 1400kgs. They WILL drive more dynamically !! Forcing a Disco along will kill mpg, especially on an auto.

Basically, relax when driving your Disco, start your journey 5-10 mins earlier to get there on time and enjoy the comfort.

Funny, but I remember growing up in the UK and this is precisely the way I was taught to drive......mind you my father was test engineer / vehicle proving for Triumph at the time. (many a time spent with him in prototype Stags, TR7's etc)

 

[thebiglad]

I'm sure to some, it will appear like 'grandad style' driving, but I don't care.

I get where I want to be, on time and without stressing myself or the car, so that'll do for me.

Used to get 580 to a tank in the TD5 with grizzly claws, patriot roof rack and lights and doing 60 to 80 from Bedford to Workington. dropped off a bit now but I think the intrcooler is choked with crap.

what do you think of setting a not official test on this matter of testing the basic mileage.

Maybe the question was too broad in a sense of different tank sizes.

Well in theory a 200, is better than a 300 and then even better than a td5.

We could narrow it down to 10 litres of fuel from the red nothing above 60 and see what we can get out of that fuel.

Then categorise it in the series

Also we got to bear in mind a standard car should get an advantage with regards to the weight they carry to a modified with winch bumpers, winches, gurads rocksliders. Road tyres to mud tyres !!

What do you think!
