Kas Thomas ( a REAL skeptic on additives) believes that Lenkite
MAY be a good thing, altho he has not written about it in a few
years and I can't vouch for his current position. At one time he
either recommended it or thought it was worth trying. A little
fuzzy, but I am pretty sure it was not negative. BTW, Kas is
the former editor of Lightplane Maintenance and current owner
editor of TBO - a very good newsletter on aircraft engines and
their care and maintenance. Sharp guy, not much BS slides past
him.

He wrote very nice warm friendly things about Av Blend's abilities to keep
cams and valve guides wet, also to free up stuck valves. His big caveat was
that soaking valves overnight in Marvel seems to do about the same thing,
and Marvel is a lot cheaper. It was on the strength of his article that I
started using Lenkite in my Lyc regularly, and on P&Ws when we have
recalcitrant valves.
I think Av Blend works on the Lyc, but only because I have not had any
valve problems since I started using it. I KNOW it does wonders for P&Ws if
you suck some into the intake manifold while the engine is running, then
shut down and wait 12 to 24 hours. I read somewhere, can't remember where,
that all Shell W oils and the new Exxon semi syn have the same additiveand
so does Lyc LW-16702.
I am hoping one of the several super knowledgeable engineers on this
site will 1) know what the secret ingredient is 2) know if it works and 3)
know if there is enough of it in Shell W and the new Exxon so that I can
quite spending an extra $18.00 bucks every 25 hours. I also thought if it is
as good as advertised it might be useful in rotaries. Going 240,000 miles in
a car doesn't show me much. Consumer Reports last piece on auto oils
indicated ANY good auto oil will provide similar service in New York taxi
cabs. tommayer
