For each engine (9) a record of 66 bytes:
 +0  20 BYTEs   Name
+20     WORD    Cost (mc)
+22     WORD    Tritanium needed
+24     WORD    Duranium needed
+26     WORD    Molybdenum needed
+28     WORD    Tech Level
+30   9 DWORDs  Fuel used to travel 1 month at the given speed, for each
                warp factor, for a 100000 kt ship

Fuel used to travel d light years with a ship of m kt at speed v:

        d * m * X(v)         d
    N = ------------    t = --- (approximated)
        v*v * 100000        v*v

N is the fuel required, t the time required (E.T.A.) and X(v) is the value from the table above. When traveling longer than 1 month (t>1), the fuel usage is calculated again each month since the ship mass changes (less Neutronium aboard).

See DISTTABL.DAT (under 3rd-party Clients) for how to correctly compute the d used in this formula.

The engine fuel usage commonly plotted/tabulated equals X(v) / (v*v) and yields a value in the magnitude of 100 at an engine's nominal fuel usage (exactly 100 with the standard list), around 900 for the most inefficient speed (standard StarDrive 1 at Warp 9). Values of 120 or lower are generally considered efficient by automatic speed selection functions (PCC, VPA).

After the engine records, 4 unused bytes follow.
