I know this has been discussed in the past but has anyone an update to the use of Avgas in petrol engines (NM Pajero 3.5 lit ULP).
I wish to run the Great Central Rd but concerned on fuel availability between
Laverton and
Yulara.

Avgas is all that is supplied at the bowser in remote communities, they have an excemption for vehicle use. This is because petrol sniffing is a huge problem and Avgas doesn't provide the 'high' so no point in sniffing it.
If you can't run avgas due to a cat on the vehicle you will have to carry ulp with you. Be sure to lock all containers up if staying at some of the roadhouse campting areas.
Last time we were out there the 3.5l rangie we had with the group went the best it ever had on avgas, 100 octane makes a huge difference.

At the moment there is no low grade AVGAS in Aust, so communities are currently having to stock unleaded.
Ring ahead to find out. There are some good shopkeepers around who may look after you, if you are going thru.
Big Petrol company have advised for modern (cat convert) vehicles to use 50/50. or alternate tanks. BUUUUUT it will stuff your cat convert eventually........
IMHO I would go the 50/50 option and only in a have to situation.
Which means that if you carry 80L odd you should only have to fill up at Tjukulya(sp?) roadhouse or maybe
Warburton.

Slammin,
do you know which outlets currently have ULP instead of Avgas. One of the vehicles in our group is going to have to carry enough ULP to get from
Marla to Sandfire Flat! If we knew of some ULP in betweensomewhere it would certainly help.

hi all,
It would be really great if there was some quantitive information as to the problems with running AVGAS in moden unleaded vehicles.
ie. How many Kilometers could one expect to do running on AVGAS before there was a real detrimental effect on the Cat. convertor and / or oxygen sensor.
And,
how many kilometers could one expect to do running a 50/50 mix of unleade/avgas before real problems with the cat. convertor and oxygen sensor appear.
Also,
are there any other problems other than those previously mentioned ( oxygen sensor , cat. convertor ) that may become evident in the future by using avgas on the odd occasion.
There seems to be a lot of conjecture on this subject , but no real supporting evidence either way !!
cheers .. Andrew
