synthetic oil additives

[rasputin@gate.net (Tom Britt)]

Can anyone advise me about usung a product called "Slick 50" (I think) in a
'52 TD? I have been told that this was a teflon-coating additive that will
prolong the life of the engine. I know not of this substance. My TD runs
like a proverbial top. The engine is like new (after much work by good
mechanics), and I hate to use something that could have a downside. I use
Castrol in it now. Is this additive worthwhile? Thanks, Tom Britt
