I thought there would be a LOT more 3.9's on gas,,,

As the D1 3.9 isn't as fuel efficient as the D2 4.0 Bosch system, your figures should be better.

well done mate...

good to see you smiling again...

Bloke who I saw today with his 86 3.5 RRC did 300 to 350km on 60 litres of gas at a steady 100km/h up to Lake Eyre. Based on my experience I would suggest you would get between 4 and 6 km/l depending on which way the wind is blowing....

Highway driving on cruise control at 100 gives me 300k on gas after using 60lt. A 60lt tank is 60 lts, does not matter what is in it, but the petrol and gas will each have different mass. ie a 60 lt tank of feathers will have a different mass to a 60lt tank of sand.

My 94 Discovery takes 67 litres LPG from empty,

I get 300 kms out of it, which works out to around 4.4 kms to the litre,
Running the mixture as lean as i can without dropping any power.
Vac advance is working and the timing at 10 deg.

Gearing is a bit different, it does do 2600RPM at 100 kph,

Blowed if I know what you are trying to say or its relevance to the subject.

LPG tanks are (correct me if I'm wrong Bee Utey) rated by water capacity and you can only fill them to 80% capacity with LPG. Thus a 70 litre WC tank (like mine) will take only 56 litres of LPG (again like mine).

What we don't know is if Pedro is talking 70 litres of LPG (even thought that's what he wrote) or the tanks are 70 litre WC.

My tank takes 60lt of gas from dead empty to click off, I have a 4.6 fitted to my DI and commuting every day in crappy city traffic and the Adelaide hills I get 250km per tank.

I was full of good intentions on my one trip away to Robe - fuelled up zero'd the milage then promptly forgot to check distance when I swapped to the petrol tank. I would like to think it would achieve 300km on distance driving or better but need a brain that keeps paying attention

What part of 70 litres of gas don't the other posters understand? You didn't once mention the nameplate WC of the tank/s.

Yes the legal lpg capacity of a lpg tank is 80% of the rated water capacity, expressed as litres or kg of water. 70 litres is the approximate capacity of a pair of 44WC tanks as mounted under a disco/rrc. Legally it may vary by about 2% from the rated capacity at 80% full.

So a typical range in city/hilly country would be 300km, heavy towing 200km, lightly laden touring economy up to 400km.
