I don't have a Singer dealer close by, didn't want to wait to order it, and so I bought some White Lithium grease at Lowe's that's used for power tools...seems to be working fine!
I read this on Sew-Classic Blog about using white lithium grease
"After 50 to 70 years the grease that lubricates the motor bearings and the gear drive gets very dirty, breaks down and sometimes even cakes up. It’s best to completely remove this old grease, clean the bearings, lubricating wicks and worm gear and them replace the grease. In order to do a through job, I have found it's best to remove the motor armature completely.
I have seen machines where someone used a lithium based grease on the machines, and it was always hard - like brittle hunks of cement which have to be scraped and chipped off of the parts. So, I always caution against using a lithium base grease for this application."
The website has a lot of information.
