 With all these comments about thick cold oil, I' wonder why no one is using
100% synthetic, which was given top marks in an extensive test by Aviation
Consumers many years ago... the leading ones being BelRay and ... and also
Mobile 1.  Still fluid down to more than minus-30F, as I recall.  I used it
for hundreds of hours in the old Continental A-80 in the Dragonfly, and intend
to use it in the Lnc2's IO-320.  It has high film strength, and always cranked
easily at cold temps.  Many manufacturers and weights  now available in places
like AutoZone.
 Any adverse comments by other users?
