Best light oils to use for various things
As mentioned three and one motor oil light weight turban oil in the zoom spout, sewing machine, oil bicycle oil these are all good lubricants that are good for most light duty purposes.
Penetrating oils are usually meant for freeing up stuck parts however they are also excellent for lubricating, an old motor or clock where the oil has gummed up the penetrating oil mixes with the old oil and actually will free it up very nicely and help The motor run properly again.
There’s really no one perfect oil for everything, fortunately, most of these low powered motors are not very critical. It’s not like engine in a car that really has to be lubricated with an exact type of oil.
