Did I miss something, or did no one bother to post anything on the DVT
fly-in last weekend????
GREAT TIME! 25 or so aircraft including 7 Yak-50's, a TW, 3 T-28's
(see, the Blue guys are starting to realize where the action is!) and
even a beautiful Spitfire came down to check things out. The -50's in
a 7 ship vic (US history) was one of the many highlights....
3 days of standard FAST, tactical formation, BFM/ACM, canyon runs, and
even an opposed road recce (a section weaving up a road looking for
targets of opportunity whilst trying to keep the bogey "out there
somewhere" from becoming a bandit).
Thanks to Cannon Aviation Insurance for sponsoring the event and some
delicious smoked pork!
TJ, Furball, Kato, Weasel, Stormy, Yoda, and the rest of the DVT crew
deserve warm accolades for putting together what is sure to become a
winter time habit in the Southwest!
Up next, the "Dust off in the Desert II" Advanced Tactical clinic in
Palm Springs March 3-6. If you are interested please contact me
ASAP...
Cheers,
Barry

Lee,
You said: Oil does not "wear out".
Actually multi-viscosity oil does wear out. Little strands that are
straight when they are cold and curl up when they are hot are what gives
the
oil two viscosities. Over time they break and don't increase the
viscosity
at high temperatures.
I did say "oil", not this synthetic garbage that is
still not proven, as far as I am concerned. :>)
And as far as the multi-viscosity stuff is concerned,
how many of us actually operate our engines at temps where this
stuff in reality has any real use? Frankly, (unless you operate
at Denver in winter as I do), very seldom do any of us go flying in
temperatures cold enough to make starting with "thick oil" a problem,
and that is the ONLY legitimate reason for having multi-viscosity
oils. Cold starts.
Personally, and I KNOW the "modern thinkers" are going
to take my head off for this, when I go flying when it is cold,
I preheat my engine up to the point where it is in a "normal" state
before starting, (engine temp at 40-50 degrees F) INCLUDING ITS OIL,
and therefore I have no need for a magic oil. And I know of at
least three instances where an engine or oil manufacturer has had to
buy MANY engines because their "magic oil" failed.
I'll keep using Aeroshell 100W in all my birds, until I
see the 50 years of experience (I already have) of good results
with something PROVEN better.
Oil is one thing I don't experiment with. It is too
important. I'll let all you "modern thinkers" do the experimenting.
I have made all the off-airport landings I want to. (Three, one at
dark-dusk, into a mountain meadow, thru power lines.)

Gents, I have received a slew of questions via personal email based on my

places where one can find this info via the Internet, and they all agree
with each other. But for those that like to have it presented free of
charge and effort, here you go.

Hey,......... Marvel Mystery Oil. I've used that stuff for years - T6,
Stearman, Bonanza, Golf cart, air tools, and now my YAK.. I mostly just
like the way it smells!
I've enjoyed reading the Banter back and forth so far. Anyone up for
arguing about wax?
