    Abstract:  I was wondering what fuel people are using in the Limbach 2000 engine.  Is it 100LL or Auto fuel(What Octane)?

    The limbach engine 2000 is listed using 100ll the compression is 8.7 to 1 and I think that you could use unleaded auto fuel of the "super" premium 98 octane.

    I use unleaded auto fuel 93 octane and a few gallons of 100LL now and then to lubricate the
    valves.

    A Grob service letter recommends auto fuel to prevent problems with lead.
    The octane numbers are confusing. The German 96 ROZ recommended by Grob is equal to
    the American 93 R+M. At least that is what a Shell fuel specialist told me, I don't have the
    data available.

    The 93 R+M supreme auto fuel is the highest octane normally available and should be fine
    for 8.7-1 compression.

    Alcohol in the fuel could be a problem and is to be avoided.

    Since 2005 I fly the G109B in France with unleaded auto fuel 98 octane
    with a lead substitute brand Wynns. The previous owner did the same in
    Germany for many years.
