I've been quoted $4100 to have my 2006 VZ Commodore wagon converted to LPG using a sequential vapour injection system. After the government rebate of $1750 dollars I will be out of pocket $2350, but I've seen ads for some systems that can be installed for $300-$400 after the rebate. What makes this system so good?

It’s a bit like comparing a carburetor with fuel-injection. A carburetor is really a compromise and is very difficult to tune perfectly for all running conditions, so there is often a problem where the engine coughs, splutters, misfires, stalls or surges. Electronically-controlled fuel-injection can be more precisely tuned to all running conditions, whether it’s hot, cold, wet, windy, high speed, low speed, whatever. The end result is that the car performs better and gives better economy. It’s the same with the vapour-injection system; your car will run better, it won’t stall, stumble, surge, and the performance will be the same as it would be on petrol. Whether that makes it worth the extra $1900 or so it would cost is only a question you could answer. For me it is, I wouldn’t be bothered with an old air-valves system, which is the cheaper system you would be getting.
