Finn... There is a better additive for your oil. It is called "aircraft
Microlon".   For all the doubters.... I have used it for years on all my
automotive engine. My toyota vans stii are going strong at 205,000 miles with
no mnoises whatsoever and start first click everytime.   My dear wife drove
my old V.W. diesel for 30 minutes at highway speed with no oil after the
drain plug fell out!  Say what you want but as always, the proof is in the
pudding as any good engineer knows.    JIM DANA

The trouble with these additives is you have to wait 200,000 miles to see
if they worked so you can't prove anything one way or another.
The best thing is rely on independent testing labs. Some of the best are
the car manufactures themselves or the oil companies. If there was any
real advantage to this stuff they would be recommending using it. It would
be highly in their interest to do so.

My Accord is running great at 225,000 with NO additive - just
a regular change (3k miles) of Castrol 5W-30.  My Ford 400 E350
monster van has 157K, runs fine - regular oil, same for my Civic at
175K.  Just because one engine survived an additive does not prove
benefit.

How do you know how long the oil was out of the VW?
Not doubting, just curious how someone could drive that long after they
were aware that there was no oil?  What happened to the engine?

DuPont (owner of the name Teflon and the originator) will NOT permit
anyone to advertise that they have an engine oil additive which contains
Teflon.  This is because their testing has shown no benefit and much
possibility for powdered Teflon to obstruct oil passages in the engine and
cause harm. If it really worked DuPont would be the first ones to get rich
and help sell it.  No really independent or scientifically controlled tests
have
been done (at least that I have heard of, and I have been paying attention)
which support the various "voodoo" additives.  Only TCP and a few other
additives have been proven and they are already in most auto oil.
If it helps, the major oil companies will use it as soon as their scientific
testing shows good results without problems to offset.  Notice that
these additives contain "PTFE" - the chemical name for Teflon, to
avoid lawsuit by Dupont.  It would be great if this stuff worked, but I
can't find any real proof and much to cause doubt.

Also, it irks me that Microlon claimed to have had their product in
Voyager and refuses to acnowledge that it was NOT.  Jeana Yeager
marrying the Microlon owner casts suspicion on her support of the claim
that it was in the engines, against everyone else on the Voyager team
adamatly saying that they did not use it.  Smells like hucksterism,
as do most miracle additives.  A few additives are real, but most are
questionable at best.

For an example of an additive that has been proven --
Porsche has recommended Chevron's Techron as a fuel system
cleaner for decades.  Now that most cars are fuel injected,
many gasoline suppliers are putting the same stuff in their gas,
some using other gas "detergents".  Stick to additives recommended
by someone not hired to advertise and that has nothing to gain
from you buying the additive, and is technically skilled.

Caveat emptor -- big time.
