Hi all just had my first long run since converting to LPG. Vans a 19DG with a 49ltr tank at the front. Gauge has 3 green lights ,last light flashes for about 40 miles then runs out. I put in 30ltrs and got 104 miles combined driving before it ran out again. Seems a bit low to me 16mpg. Is there any way it can be adjusted for beter consumption. Thanks in advance.

Who fitted it ?
When I had mine done at Gasure in Chester, iirc, he asked me to come back after a weeks use for it to be re-adjusted after it had "settled down".
He adjusted it and I was getting around 22mpg

There is a fairly obvious "mixture" screw on mine in the gas feed pipe that goes to the carb.
Steve explained, when I asked, how it worked.
A quarter of a turn out richens it = a bit more power and more fuel used.
A quarter of a turn in = a bit less power and less fuel used.
I have done some careful experiments on mine, checking the results of various settings and have settled on one I like.

HOWEVER I cannot recommend or condone the end user adjusting their own LPG installation, especially if it a recent Gasure job !!
I know Gasure prefer us to contact them to have any adjustments made.

If there's anything you wish to question speak to the man himself ... accept no lightweight imitations :mrgreen:

with the power valves slowly screwed in till the engine falters at 3500 rpm then cracked back an eighth, I got 24 mpg at a constant 60, the trade off was a remarkable loss of power for hill climbing.

2.1 on carb

his gasness Steve Shaw at Gasure will enlighten

Coming home from Cornwall all loaded up, with the taps open for the power sapping hills, I got 18.2mpg
