Thread: Whats different in dedicated LPG engine

LPG has higher Octane rating so can run more (advanced) timing, ignition and cam and higher compression, would also have hardened exhaust valve seats at least, Regards Frank.

It will probably run well on 98 octane premium unleaded when set to optimum LPG specs.

Thank you Tank and bee Utey.

Appreciate your input and engine may be worth further investigation.
The engine has the heads off, and is suppose to have been reconditioned is there anything I should look for and look out for so I'm not buying a dud.

Cheers

However a standard 3.5 engine with no mods other than the LPG system and advancing the timing will run perfectly on lpg. Mine does.

The suggested mods will also improve running on petrol as well.

I went to go look at a RRC for sale recently and apart from the car being a total shed and the asking price being faaaar to high it was on LPG only. That put me off big time as your pretty screwed if you run out in the bush! Not like you can get a mate to bring a jerry can bottle out to ya! (Or can you and I'm just not aware of it?)

All you need is a suitable hose for connecting a gas bottle to your filler point and any swap-and-go 9kg or similar bottle can be used as a jerry can. Been doing it for years.

Taxis have been doing this for years too even if your not supposed to

My 101 was converted to LPG (dual fuel) early in its civilian life and did was used mainly used across the top end. The previous owner said that they bought a couple of large household gas tanks and carried them to decant from them to the 75l tank in the vehicle. As a result it was able to travel across the top end on LPG. Totally illegal and as said it does happen.

With the correct equipment and gas containers decanting is quite safe - afterall that is what you are doing when you fill up with LPG at a garage. With the correct regulation and checks it would be quite doeable but I guess there are vested interests to keep the status quo.
