I'm looking at getting LPG for my Mazda 6 GH Wagon, but I have received conflicting information from LPG fitters. One says that the better system for the car is a mixer-based system, whilst another says the new injected system is the way to go. The first place claims the mixer-based system is more reliable. Can you shed some light on this?
Cars built after 2003, such as yours, must be fitted with a system that has been emissions approved, and I would very much doubt that anyone has mixer system that is approved for your car. The mixer system is old technology and is nowhere nearly as good as the newer injection system. Although injection systems are more expensive they are the best option.
