I am happy that my favourite gossip shop is up and running again. Can I
repeat my earlier question about Teflon additives to keep my manual P6B
As you know, I am on my third P6B manual gearbox. I believe that this
present box is not long for this world. The main input bearing,
especially, makes its presence felt. The box is filled with HPR30, which
is a semi synthetic SAE 20 - 60.
My question is this. On the market are several Teflon additives which
promise to shut up noisy engines and gearboxes. Can I safely use one of
these additives without compromising the already limited (INMHO) lifespan
of the box?
Vern has advised against us ing SAE 90. The HPR 30 is a SAE 20 /60
semisynthetic (whatever that means). The book suggests a SAE 20 /50. In
many ways, a Teflon additive to the box should be like a Beta Blocker for
old geezers like myself. The question is, does it work, especially in
boxes that are on borrowed time? Were I to be adventurous, TQF hydraulic
oil has been another suggested possibility, but all I want is to get the
bearings to shut up.
