I am surprised they did not send you to the drug store for KY gel!
Most anything will help-- I use a dab of wheel bearing grease in the O-Ring groove to help hold the O-Ring in place and a little on the top. This is to keep the O-Ring from rolling and coming out of the groove when you tighten the filter. Also a little in the center seal to help it slide over the nipple.
Some just use a little diesel fuel! Not a good idea to fill the new filter with diesel-- you will send un-filtered fuel to the injector system!
