I'm just talking about chain oil, I don't have a solution for anything else 🙂

Parafin seems easier to make at home since it's has been used for candles for a long time (since like the 1800s). Plus you can salvage candles in a pinch, and dipping a chain hardly takes any Parafin from the pot so the same pot will last decades. I've been using the same Parafin pot for about 5 years and the level hasn't noticeably changed.

Not to mention that using a dry lube like parafin greatly extends the chain life because it doesn't collect dirt and sand that increases chain wear, and you wouldn't want to have to find a new chain.
