If you've got a TSC (Tractor Supply Co.) store in your neighborhood, they have a better selection of fluids than the average "friendly local auto parts store"- - - -which you'll find abbreviated "FLAPS" on this forum. The lever-arm shocks will work with virtually any lightweight oil such as power steering fluid. NAPA also has a better selection of gear lubes than most FLAPS since they service commercial customers like trucking companies, but you'll need to find a counter man who is willing to do a little research. The 20-something mouth-breather computer jockey at the front counter of some parts stores thinks it's an imposition on his important text messaging time to actually look up something in a paper catalog or listen to an oddball request from the customer whose purchases are generating his paycheck!
