Kia Sportage 2010: Converting diesel to LPG?

Asked by Peter Inns

Is it worth fitting a dual-fuel LPG/diesel system to my new Kia Sportage? I've heard it gives better power and economy, but it's not cheap.

The manufacturers of duel-fuel systems for diesels claim around 20 per cent better performance and economy, but there are also horror stories about blown engines. My understanding is that the systems are designed to deliver fuel consumption savings, but a side benefit is an increase in power. If you drive your vehicle the same way you did before the conversion you will make the fuel consumption savings and the engine would probably be ok, but if you make use of the extra go in the engine, as many people apparently do, you won’t get the fuel savings and the engine will be at increased risk of damage. I wouldn’t recommend it, and I certainly wouldn’t recommend it on the new vehicle when the warranty is still in play.
