Zoom spout would work fine. Any weight oil will work.
Zoom spout oil is definitely NOT food grade
Ok so would I drink zoom spout, probably not, have I ingested it probably use since it's what we use to maintain and lubricate out mix masters and other food processors.. Any oil will work and the old 3 in 1, is a fail safe. It can be used on everything from tools to sewing machines. As long as it provides a slippery surface, I use zoom spout since I have lots on hand and it is meant for bushing/bearings where there are minimalis tolerances for parts to move in. On a personal note if you have any corroded parts that are seizing use a drop of brake fluid to break down the corrosion and then clean and relube. A lil known fact is that ATF transmission fluid is an awesome weapons/parts cleaner. It is slightly acidic and breaks down carbon in an excellent fashion. It does not affect blueing and penetrates quite well.
Just my 2 cents
