I just lubed my older pse polaris express with some Dupont teflon lube spray(just a little on the axels/cams and cableslide)its about 5$a can. its good for everything. Dont use wd40.! There is some other spray thats in a black can its in the Martin archery catalog(cant remember the name) its also very good spray but hard to find and a little more $$. also make sure nothing is loose on your bow.
