Ask Smithy Xtra Kia Grand Carnival gas conversion

I want to buy a 2007/2009 Kia Grand Carnival, which would still be under warranty, but before I do I would like to know if it can be converted to LPG. Some fitters don't recommend it, others were happy to fit it. Does fitting it affect the warranty? How does it affect the fuel economy? How does it affect the interior space?

It does affect the warranty in as much as the carmaker’s warranty would no longer cover the engine and anything affected by the installation of the system. If you wanted a warranty on those components you would need to buy a warranty from the LPG system installer. As a general rule a vehicle uses around 20 per cent more LPG than it does petrol, but the extra fuel is offset by the lower price of LPG. EMR have a sequential vapour-injection system that is said to work well, and the tank goes in the storage cavity in the rear, so there is minimal impact on the boot space.
