Any good oil of the appropriate grade will be fine.

If you run on gas most of the time you will find your oil stays clean for longer.

IMHO yes use the oil you are currently using if you are happy with it, HOWEVER there are many on here that know oils a lot better than me. And there might be gas oils on the market.

A car that runs on gas is generally cleaner than a petrol one so your oil won't get as dirty. I had a friend that had a tried L300 that tended to blow a little blue smoke, however after 12 months of running on gas, smoke had stopped and compression had lifted. We put it down to the engine running cleaner. Mind you we didn't strip the engine to check. To much of a bugger to get out.

jeffI use Penrite HPR Gas (http://www.penriteoil.com.au/products/motor-oil/hpr/hpr_gas) on my 4.6, I did run HPR Gas 10 (http://www.penriteoil.com.au/products/motor-oil/hpr/hpr_gas_10) for a short time but wasn't sure that my oil pressures were any better when hot so went back to the HPR Gas, which is stocked more places.

(I was running Penrite oils before the conversion.)

An oil that has 'suitable for LPG use' in it's applications would be the best.
These generally are formulated to resist nitration better than most oils.
While yes, the oil stays cleaner with LPG, nitration can be a real issue, I've seen some test results from here in Oz on two turbo diesel vehicles with LPG injection and the oil was toast (excessive nitration) before a regular 10,000km oil change, and this was using a premium synthetic diesel oil.

Have been using penrite hpr10 gas in my lpg 81rrc oil fairly clean at 5000km change intervals. Not really sure of the actual cause but I recently changed from hpr10 gas in our lpg falcon to gtx3 which they say is suitable for lpg. The oil ended up much blacker looking at change time using the gtx3.

We use penrite HPR GAS 20w/60 in our LPG Mitsi work vans & have done for 20yrs.We also supply this oil to the Dealer if the vehicle is under warranty for them to use in our vehicle.We generally change the oil every 12 to 15k,& have never had an engine problem.
We now have a Hi ace with factory LPG,it will be interesting to see what oil Toyota use ,it hasnt been for its first service yet.I bet they use Toyota oil,whatever that is.The penrite gas 20w/60 may be to thick for it?

When we were using a lot of castrol synthetic refrigeration oils,in the late 90's,the Castrol rep told me ,castrol GAS oil was no different from their other oils,just different packaging!This situation may be different today.

That doesn't surprise me in the slightest.
Way back when I had a 351c on LPG I used Penrite gas, but after building a new engine I switched to Mobil 1 15W-50 and occasionally Rormula R 10W-60 or BP's full synth Visco whatever. They all had ok for LPG use on their labels.
