Much song and dance has been made about LPG power and its environmental benefits, but is it really a viable alternative to diesel (and to a lesser extent petrol)? Interestingly it's 50% cheaper at the pumps than diesel, which sounds very attractive especially since the 2p fuel-levy increase came into effect recently.

CM decided to settle the argument once and for all by taking three indentical vans powered by three very different fuels (diesel, LPG and petrol) across foggy London town to see for ourselves. The results aren't what you'd expect. Look out for the full report in the 17 September issue of CM.

What are your experiences with LPG? If you've dabbled or currently own a whole fleet-load of LPG vans/CVs I'd love to hear about it.
