fuel economy on LPG, dual fuel question, hub question

Hi there,

My fuel injected GQ gets around 24-27 (highway/city) litres of lpg per 100 km. Its a venturi mixer setup, not injection. Is that about right?

Also, how often should I run a tank of petrol to protect the valve seats etc?

Sometimes my hubs don't disengage from the locked position even though I've unlocked them? They seem a bit sticky. How can I fix that?

Thanks

Justin.

Hi Justin,.
Just saying mate, the forum likes it if you put a quick hello post up in the introduction section before getting into the Nitty gritty. Anyway all I can say is I have a 4.5l on LPG and I get about 21 / 100 highway. But under full load (me,wife and three kids with all their crap and a roof piled high) has been up to 30 /100
