I AM considering converting a 3.8-litre V6 Commodore sedan and need advice on the best gas option. My main concern is cylinder-head-valve lubrication.
The 3.8-litre engine is fine on LPG, but to ease your fears you could add upper cylinder lubricant to the petrol and that will help lubricate the valves when you run it on petrol. Other possible solutions include lubrication kits. I don't have experience with them, but have recently been given a kit to test so I may have an answer on that soon.
