This has been around for years and was the usual staple of those who wanted value for dollar.For this you will need 10W30 Motor Oil, Mineral Spirits, and an old empty chain lube bottle.For those who don’t know Mineral Spirits also are known as Paint Thinner.The ratio is 1 part Mineral Spirits to 3 parts oil. Once you add together in bottle , shake, and apply as you normally do to the chain.This is good in most conditions, it’s just like any lube you buy but you get more for the dollar.
