What kind of MPG are you guys getting on LPG?
My commute is around 20 miles each way. I have an option of going cross country with lots of windy corners, stopping, crossing main roads and accelerating back up to 60mph or taking the motorway which has 2-3 miles of stop start traffic at each end.
I leave it up to the satnav to decide which route I should take on any given day as it gets traffic updates etc.
I'm averaging somewhere around 14mpg on LPG.
