I'm sure this question has come up before but I haven't seen it. Our '85 
Westy has about 110 K miles on the (2nd) engine, I am about to do an oil 
change, what are your feelings about using an oil additive such as Slick 
50 or something simular?  My mechanic says "It probably woun't do any 
harm"... Will it do any good?  Will it make those first cold morning 
starts any less drag on the engine? 
Thanks for input
