    Fuel for Thrusters

    Is it MoGas or UL91 for Jabiru-engined Thrusters? I ask because of something I just got around to reading from last Aprilís AOPA magazine. It said garage forecourts would be moving to fuel containing 10% ethanol (E10) which attacks the alloys in fuel lines, rubber seals etc.

    Ethanol has been lurking in fuel for many years ranging from 5% to around 13% currently especially in cheaper supermarket fuel.
    Jet and Esso claim to use small amounts of ethanol but won't give a percentage, I've used the ethanol testers on both brands and couldn't detect ethanol so they're my 2nd choice if no super unleaded is available in the Quik.
    I used to run the jab on super unleaded, this reduced the chance of ethanol but not strictly removing it 100%, throw in some avgas from time to time, checking your filter/fuel lines regularly is pretty much all you can do.
    G-HAMS a pretty quick Quik

    You can run Jabiru engines on mogas, UL91 or 100LL. So if you want to avoid ethanol completely use one of the aviation fuels.
    Otherwise, pretty much what Dave said.

    Unless you're flying hundreds of hours, I'd suggest the extra you pay for 100LL is well worth the security in knowing that there is no ethanol in it.

    Esso unleaded is still testing as Ethanol free at my local esso station and obviously the added plus that there is no lead and its cheaper than avgas

    Cheers, all. Do you tend to store it in your hangar (assuming there isnít a supply at your airfield) or do you bring it with you each time?

    Bring it fresh. Fresh fuel is good, it goes off after a while (so people say anyway - could be an old wives tale).
    There are rules about fuel storage that you don't want to fall foul of too.

    Do you use a big metal Jerrican or lots of little plastic ones?

    Best not to store it in the hanger, at Lucon we have a separate container just for fuel.
    Generally for the club aircraft there's a max of 1-2 weeks supply of fuel in storage.
    However I do know of a school in France which stores up to 900 ltrs of fuel in a specialised bowser on a car trailer https://www.pegase-carburant.com/pro...ation-highway/
    I guess it takes him a few weeks to get through that even when busy.
    The three most useless things in aviation:
    • The air above you.
    • The runway behind you.
    • The fuel in the bowser.


    Rule #1: Always tie your aircraft to the largest heaviest object available. The planet Earth meets these requirements and is readily available in all locations.
    Rule #2: The great thing about twin engined aircraft is, if one engine fails, the other engine always has just enough power to get you to the scene of the crash.
    Rule #3: You can never have too much fuel in an aircraft. Unless it's on fire.

    Semper specto in clara parte vitae.

    Martin,
    I don't think it's old wives stories, but I also think it takes longer to deteriorate to the point where microlights won't run properly on it than the forums rumour mills would have you believe. I've not found any definitive information and I'm far from qualified to do my own experimenting

    Halibut,
    Me being the boring type that checks for the current official guidance - you can see it here. If you choose to follow the links within that document to the full legal regulations, don't blame me if you get brain ache
