What kind of grease is best for old plastic gears? Here are the choices I have on hand:

Unless you know different I vote no no and no..Just sewing machine oil. Can you find a manual?

For the gears? I thought the rule was smo for metal on metal and grease on gears. The instruction manual says nothing about oil or lube at all. Apparently, as Donna 13350 and Quilted Sunshine noted, they thought the grease would permanently lube it. Lol, it must have lived longer than they planned for its obsolescence to take place.

This is a good guide as to which oil/grease to use where..

Read carefully the caution on plastic vs. nylon gears..be sure you know what your gears are made out of.

I would go for oil when ever possible. I guess it's for the Singer in your other thread. I can let you know that a lot of current medium priced Singers (and other brands) are oiled. Even if they are so called lubrication free, they are meant to be oiled during a service. Except for the step motor and circuit board, most machines part are much the same as on vintage models. To sum it up, unless grease is absolutely needed I would go for oil. All moving parts you can get to with out too much fuzz on a regular basis are better oiled, it reaches the inners of joints and hard to reach places and is much less messy. Grease is mostly for places when you can't afford any spill or mess, and when you need the lubrication to last longer between applications. Oils are generally safer for plastic parts, some greases are said to contain additives that make them risky for plastic parts, and it's hard to know which ones are safe.
