Hi Macca
The Shell refinery at Clyde has closed and they just import fuel from O/S. I don't know about Brisbane. The stain in the fuel is just a dye to differentiate the types. If it is damaging fibreglass tanks then it is likely that methanol is added. We don't use it at all, only Caltex -and that from a station which does not have e10 unleaded. Don't forget to reclaim the road tax component from your fuel bills if the fuel is used exclusively for aircraft.
Regards
Glenn

I am wondering if others in Australia are seeing a change in 98 fuel. Ours comes from Brisbane and I think is from Shell but for past 3 months has a very dark brown stain and more recently there was one lot with a deep orange colour.

The issue is this new "stain" in 98 fuel really stains even correct German (with release note) clear fuel line and within say 6 weeks makes the tube a very dark brown and you can not see fuel in tube.

Also recently Jabiru Aircraft have said DO NOT USE SHELL 98 in Jabiru aircraft which have fibreglass tanks as it is reacting with the fibreglass tank. Jabiru now say use 95 or Avgas even though most Jabiru s require 96

My concerns is this will show up in Turbo and Motorgliders like Duo and Arcus in the plastic tubes in the LHS of rear seat and may react with motorgliders like PIK 20 which have glass tanks.

It could well be other states are not having an issue but think it is worth keeping an eye on and can send photo to anybody who asks. All this has come in over the last 3 months or so.
