V6 T5/Multivan

[Tornado T5]

Just wanted some feedback from anyone that owns a V6 T5/Multi. I have a friend that wants to try the newest technology Liquid Injection (LI) LPG (not vapour injection) system on a V6 T5 however he would like some real world average fuel useage for his "spreadsheet" before he makes a final purchase. I'm also interested because LPG is now 1/3 the price of diesel in Melb and if the claimed economy difference between LI lpg and petrol is between 5-10% then the figures even allowing for the conversion and initial purchase price of a V6 VW need more serious analysis.

I actually raised the question with my dealer after the oil cooler replacement if VW were looking at LPG more seriously now that the pricing gap is enormous. I know that the engine warranty is voided atm if you convert to LPG however if sales drop off due to diesel pricing they can't sit back forever.

In my own case, the ease of towing with my tdi would keep me away from a petrol/lpg unit unless the fuel use increase under heavy loads was less dramatic then what I experienced in my previous pet/lpg T4. It's also becoming more difficult to recoup increased cost with customers.
