    I enjoy the honor of 'piloting' our wind generator, a Pratt Whitney R2800-CB3 18-cylinder radial. I recently encountered great difficulty finding Aeroshell W120 oil due to very high demand from the fire dept. A lot of old radials were fighting fires.
    We have always used the same Aeroshell W120. Phillip's recently introduced a multigrade oil. X/C 25W-60 is marketed to owners of old radials. Has anyone tried it?

    Don't use a multi viscosity oil in a large radial engine.
    Stick to the W120 or 120.
    Read the information in the link.

    Also remember in Aircraft engines with silver bearings you DONOT want any
    oil with zinc additives in it.

    Oh and since you are in CA I see no reason to even consider a multi grade oil. Its not like it freezes there.
