With the great debate about which TCW III oil to use I sent some out
for testing. you can see the results here

http://home.comcast.net/~team_doughe...s/results.html

From my limited knowledge of oil I would say of the 5 tested they are
all pretty much the same. With the exception of mercury and yamaha
brand. they have molybdenum in them. Not alot but some.

I did post some links to other sites that explains what the additives
are and what they do.

Do what you like with these results.
