[AT] Penetrating Oil Test

[Ken Knierim]

Gene,
   VERY interesting data. I know Kroil works well from when I helped restore
WWII warbirds for a while; that was all they used and it worked wonders. The
data indicating the ATF-Acetone works better is something I'm going to play
with. With all the ATF types out there, did they mention which one they
used? Was it regular Dexron II or one of the many other available variants?
I have Ford Type F, Dexron II (or is it III these days?) and the synthetic
type specified for my Dodge available.

Thanks!

Ken in AZ
