I am yet to see an accurate LPG gauge in a car.Originally Posted by walker
Did the first fill-up today.
Spent the past 2 days driving in peak hour traffic and got 22l/100km which sounds about right. I'm sure (hope) it will be a bit better with normal driving although I was usually getting 19-20l/100km on petrol.
The best thing was when I worked out the cost it came to $8.60/100km
Once thing does worry me though. The red light lit up on the gas guage after had only done 165km! As far as I knew the tank should be 60 litres usable. I was getting worried thinking I was going to be getting over 30l/100km but when I filled up it only took 39 litres. I will see how it goes on this tank and will take it rightout to empty but I am wondering whether the tanks are filling up properly.
I always wondered how those tanks filled to there stamped limit. With a normal gas bottle you have the pressure release valve where you undo it and fill the bottle until a heap of fresh frosty gas flows out it and you know the bottle is full. But with a car how dose this work to fill the car bottle to full if you do not have a pressure release valve to check when the gas gets to the top and pores out. ?

Loaded Disco.
With the "frosty gas" you are basically letting gas flow from 1 cylinder to another, this is called decanting and relies on a pressure differential- ie depressurising the recieving cyl by opening a bleeder. The sending cyl needs a special valve that draws from the bottom of the cyl ie liquid withdrawal.
With autogas you are PUMPING the liquid gas in and they generally spray fill which tends to lower the vapour pressure build up. In any case the vapour will turn to liquid under enough pressure.
The AFL (Automatic fill limiter) is basically a float valve that stops filling by closing the valve- like a dunny cistern- at around 80%
I would say that each of the 3 cyls would have an AFL and when 1 fills then the other 2 get more gas until full.

so over 3 tanks he looses 60% useable lpg..... I would want much bigger tanks.... maybe you could get some fitted in yr off road trailr walker?? Fork lift bottles?Loaded Disco.

No, the tanks are joined and there is only one AFL...
So 3x30l tanks would be 1x90l tank
AFL would cut in at 72l

right stilll i small amount of gas.... i produce more then that after 6 beers

Yes, we know you do!right stilll i small amount of gas.... i produce more then that after 6 beers
DeeJay and Tombraider and all others thanks you have totally answered my question. Thats still a lot of gas and mileage from those tanks. I would say on a very rough guess that would give you another 500Km. ?

You wish, I don't think you would ever get the economy that good.
I am pretty sure the tanks I have are meant to give 62l useable. That should give me around 300km of city driving.

therin lies the problem cause it wasn't that much cheaper...... it still cost me $3950 !!! did i get ripped ?
