Hi jeffo i have a 3.5 on lpg in a 110 and i must say that i do find i seem to get a lot less per liter in winter or i may have a problem as well.

"Throw us a bone" You haven't really given enough information for anyone to start trying to help.

Is the engine running badly? what LPG system do you have? how did you measure the poor consumption, full tank to full tank? If you run petrol, what is the consumption on that.

For the record I expect between 3 and 4 miles per litre depending on driving conditions etc. If you really are getting 1.5 miles per litre from a reasonable engine, something is up.

engine runs as sweet as a nut especially on lpg i have a omvl vaporiser,put new plugs and leads,runs better on lpg than on petrol

i tested full tank,left it run empty,then filled again,i now have turned the screw on the vaporiser in seems a bit better
