There was some discussion in 'The Courier' (TSSC monthly mag) a while ago about
this topic. The concensus then was that silicon (DOT5??) (NOT your normal type)
brake fluid is the stuff to use (for easy fitting and long term anti-sqeak) as
this is the most similar type of compound to the actual bushes themselves. This
stuff is v. expensive and normally used in racing applications due to its
superior performance at high temperatures. Apparently if mineral oil based
compounds (including Vaseline etc) are used then this *may* cause longer term
degradation to the bushes.
It was also noted that you should never use washing-up detergent to ease the
fitting of bushes as the salt in it can quite quickly corrode any metal parts in
contact.
I'll end by saying that I have no personal experience of using Si fluid...just
adding in my 2p worth.
