lucas?

Planning on changing both eng oil and trans oil this wknd.Just wondering if Lucas is worth it.Should I cut it or use it straight?Getting close to 200k on my 88 vic wgn 1.5 5 spd.Any opinions on the additive Engine Restore or is it junk? Should I use all Lucas in tranny? Thanks in advance!!!!!

There is a big long thread on this in the Engineering/technical forum if you want to walk over there and do a search.
