Just filled up the L322 with LPG and as promised I would update with the MPG:

224.1 Miles, 72.48 litres LPG @ 79.9p = £57.91

Works out to be 14.09mpg and £0.26p per mile - OBC reading was 17.3mpg and as gas is around 80% efficent as petrol that reading is fairly close.

My P38 DSE was averaging 25.21mpg and £0.26p per mile, so they are comparable on fuel costs so far, lets see what the next fill up is....

25 mpg = around £0.19 pence per mile over here on diesel. Shame about the rip off fuel prices in the UK.

They're looking into drafting a new law which will force forecourts to lower prices when there's an oil price change - since now they jump at the change to raise them, but take ages to lower.. fingers crossed for that one.
How come LPG's ~80% as efficient as petrol? It's a shorter carbon chain, should undergo more complete combustion?

It burns cleaner as you say with complete combustion...but the energy created (the Calorific Value) is less, therefore it doesn't create as big a bang....

Oh I see what you mean - less energy per litre of fuel, of course.

Saint, I work that out at 23.58 mpg (£57.91 divided by cost of 1ltr petrol, £1.34 = equivalent amount of petrol yu would have purchased for that amount of money. That's 43ltrs of petrol equiv. divide by 4.55 litres in a gallon which gives you 9.5 gallons. 224 divided by 9.5 gives 23.57 mpg.

I would have it serviced for c.£100 and then you should get more than 26-28 at least.
