I have a FJ75 1988 Troopie with 3F motor. Its been running on LPG for 10 years. Engine still runs good, minimal oil consumption between 10,000km oil changes, motor done 300,000.

It spends 95% of its time on LPG.

Should I bother with installing a drip lube and using valve saver? I heard that the valves in these motors are OK with LPG, but other mechanics say no you still need to run a drip lube if you run 95% on LPG, no matter what the engine.

I've never bothered with it and never had a problem with valves, 300,000 on LPG with my old VL Commodore and it was as good as gold when it went, 80,000 with a ED Falcon...good as gold, 30,000 so far with a AU Falcon and my Lux has done approx 100,000 on gas and appears to be in good condition.

Word around the traps when I owned a cruiser with the 2F was they are bad with burning valves. True or not, I don't now, but I trusted the people who told me.

When I bought an FJ62 with the 3F running LPG, no one could answer my question, so I spent the 30 odd bucks and put a valve saver kit in. I thought it better to do that rather than spend $$$$ years down the track on a recon, or new head.

Cheap insurance.

Falcons have always had a good rep for running on gas.

P.S Your carby won't like not having any petrol in it.
