    Very Ketil, I just checked out your website. Looks like a great job on restoring that Ju-88. Will this aircraft be able to fly when done?

    I'd contact Mike Nixon of Vintage V-12's check out our web page at Vintage V12s

    You don't really need 87 octane fuel. Your local airport should have an appropriate fuel. General Aviation fuel will work. Here's what he mailed me to a few questions about Synthetic Fuel and using 100LL.

    I've talked to an engine rebuilder that has overhauled quite a few DB's and he sets them up to factory specs. He runs them at 100% power on 100LL wit no problems at all. Of course with 100LL they won't run them at WEP settings just as the Merlin's he rebuilds.

    My questions:

    Hi Mike,

    I've always been intrigued with the synthetic B4 and C3 fuels the Germans
    produced from Coal.

    Since you've posted your website and you have rebuilt DB 601/605's and
    now in the process of rebuilding a BMW 801; I'm curious as to the fuel
    you are using to run the engines in.

    I have chemical breakdowns of them and the percentages of the
    hydrocarbons and additives are much different than fuels derived from light
    crudes.

    The question/s I have are. Do you have a fuel specially blended to
    match the Synthetic B4/C3 formulation? If not how demanding is setting up
    the the injection pumps to run on crude based fuels and is there a difference
    in the boost pressure maximum that can be used?

    Thanks so much for your time and answer.

    His answer when I asked the question on fuels and how they run them without having a synthetic fuel with the qualities of German fuels of WW2. Mike Nixon of Vintage V-12's sent me this answer to my question.



    Best,
