Likely the best available synthetic, 'bet it's better than Mobil 1, but I'm
not sure. 'Been retired from B-52's 27 years. 'Been 49 years since I was a
maintenance crew chief/mechanic on B-47's; I remember taking 2 and 3
24-quart cases of oil up on the wings to refill the six lub oil tanks after
a 12 or 14-hour flight; 'think the tanks were about 15 or 20 gallons or
more - don't remember for sure. Probably same for B-52 and others. I was
amazed at how thin the oil was/is -'course, it has to perform (lub bearings
spinning at 20+ krpm) at high altitude, -55F.
BTW, does anybody else recognize the blue vertical stabilizer sticking out
of the Hudson River as the same as that on a B-47? How 'bout the
under-wing, break-away engines also pioneered by the B-47, circa 1947?
