Injection power

THE two types are the older Venturi/mixer system that has been around for 30 years or more and done a pretty good job. It will save fuel, but you will lose power and the driveability won't be as good. The other system is gas-injection, used on most modern cars like yours. It will give you the fuel savings, you won't lose power, and the driveability will be better than with the old system. The downside to the injection system is it's more expensive. You could fit an old Venturi/mixer system for about $2500, but an injection system will cost about $4500. I would recommend the injection system even though it costs more. Shop around to find the best installer in your area. Look for brands like Eurogas, Impco, Global Autogas, Speedy Gas, Apollo and so on -- they're all well-respected.
