Holden Captiva: Converting to LPG

The LPG system manufacturers are working on kits for the Captiva and they should be available within weeks. From what I am told they are developing both vapour and liquid injection systems, and either would be fine. Of the two liquid injection would be the better, but I would expect it to be more expensive. Generally you would pay off the cost of a vapour-injection system in about 12 months, which makes it a good proposition given you plan to keep the car for five years.
