In Breath of the Wild , there aren’t oil jars as a standard item; the search results available point to Tears of the Kingdom , where oil jars can be bought in Rito Village at The Slippery Falcon for 12 rupees each and there’s also a free stash at Hebra Trailhead Lodge.

If you meant BOTW

BotW doesn’t use oil jars the way TotK does, so you may be thinking of a different item or the wrong game. If you’re trying to make fire-related gear or bait in BotW, the item you need is usually something else entirely.
