油 is an Artisan Good and common cooking ingredient made from the Oil Maker. It can also be obtained from Pierre's General Store for 200金.
Oil is given no quality rating, so its sell price doesn't benefit from quality increases. In addition, despite being labeled an "Artisan Good" in-game, its sell price does not benefit from the Artisan Profession. Its main benefit lies in its use as a cooking ingredient, however, oil made from base quality sunflowers, cultivated sunflower seeds, and all qualities of corn is profitable, though corn is more profitable in the keg or preserves jar.
