    Post 100LL and Octane 100/130 not same

    Flight Simulator error 100LL fuel for Warbirds reason?

    Asking a question: 100LL and Octane 100/130 not the same chemistry that correct or incorrect?

    (figure) "Octane rating"

    (Point) Motor Octane Number (MON)There is another type of octane rating, called Motor Octane Number (MON), or the aviation lean octane rating, which is a better measure of how the fuel behaves when under load, as it is determined at 900 rpm engine speed, instead of the 600 rpm for RON.[1] MON testing uses a similar test engine to that used in RON testing, but with a preheated fuel mixture, higher engine speed, and variable ignition timing to further stress the fuel's knock resistance. Depending on the composition of the fuel, the MON of a modern gasoline will be about 8 to 10 points lower than the RON, however there is no direct link between RON and MON. Normally, fuel specifications require both a minimum RON and a minimum MON.

    We will relieve such a problem thing for Microsoft Flight Simulator 98; 2000; 2002; 2004 and X, Because of 100LL fuel not same Warbirds? Found out earlier that when I fly the aircraft of the Curtis P-40 Warhawk (the same every body who fly any warbirds such "Noth American P-51D Mustang or else."

    Well, MFS have a fuel for Jet and 100LL only that right, but WHERE IS THE "Octane fuel" FOR MICROSOFT FLIGHT SIMULATOR?
    That's octane fuel for military aircraft as for Roll Royce and Allison engine that following the octane fuel for United States Army Air Corps, after then, United States Army Air Force, United States Navy Avaitor and United States Marine Aviator in the World War II, it not that "100LL"?

    "FLIGHT SIMULATOR REVIEW" USERS POSSIBLE REPLY.


    THANK FOR KINDNESS IMMEDIATELY DISCUSSION!

    It is all buried in underground tanks at Area 51. When you find it please don't let anyone else know. In the mean time use water, coke, corn syrup, or anything else you have around, because FS doesn't care what you use. For the pilot plenty of coffee or Red Bull, because Red Bull gives you wings.
    Thanks,

    Jim

    Look at all the money you save flying your Mustang on 100LL. I couldn't afford to fly mine if I had to buy "the good stuff".

    You won't find it, as MSFS doesn't distinguish between the differing grades of Avgas or Jet fuel either.
    100LL is what is used, that is all MSFS knows. The R-4360 engines used on the B-377, C-124, B-36 and others required 145 octane fuel for performance reasons, largely Anti Knock (anti-Detonation). Otherwise one would have to cut back on power output to compensate for the lack of knock resistance in using 130 grade Avgas.
    Same could be said of Jet-A and JP-4, JP-5, and the now standard JP-8. JP-8 is not the same as Jet-A.
    The JP's are all different fuels that MSFS lumps into Jet-A for sake of it's programming. One size fits all is MSFS's answer to keep things simple for all the fuels.

    ...but WHERE IS THE "Octane fuel" FOR MICROSOFT FLIGHT SIMULATOR?
    It's there, in the form H2o injection(Lake Water). Add N2o(chemical supercharging) for mo' power.
    FS engines are specially constructed and tuned to use the 100LL available. The knock sensors and ignition retard mechanisms are computer Monitored/Controlled, so they are transparent to the end user. If the computer isn't up to snuff, Newegg.com can help.

    Seeing that all of those old Warbirds have had their engines brought up to speed in the RW with Tri-metal Bearings, High Density Forgings for the Pistons, Stainless Valves, and Hardened Valve Seats, 100LL and H2o injection should be OK.
    If not then the myriad of custom fuel blenders will have you covered.
