Been using the Adams Worm Gear 680, do you recommend any other type of oil to use?

Been pouring it in from the top (see picture)

Oil level tube gauge shows it about 5/8’s full
Seen instructions from Otis and Hollister that says it should be full or ¼ way to top, what’s your take ?

For the grease fittings / zerks, can i use the same Adam’s worm gear oil to inject into the fittings?

Any recommendations on a grease gun?
