Any general purpose chassis grease will work, but be VERY stingy with the amount of grease you use- - - -too much grease has a bad habit of blowing out the pump seals. DO NOT use a pressure gun- - - -hand pump only, and only a little bit! Maybe every 6 months or so, depending on how much the engine is run.
