I've done some research on axe maintenance and it seems gun oil is the best lubricant for axes. However at approximately $10 for a 4oz. bottle cost becomes an issue if you get a lot of use out of your axe and oil it after ever day of use. Is a cheaper alternative like 5w-30 motor oil adequate?
I will note that if its ok to spraypaint my axe head, then the cost of using gunoil becomes cheaper since I don't need to oil the entire surface.

I'd say almost any synthetic oil would work. I know people that use Mobile 1 Synthetic on their rifles.
