It's quite tricky to get it, you need to use something you may have came across during the game. I don't want to give much spoilers tho! It's nothing to do with the bottle, but you did use it correctly! It's supposed to slow down the meat worker that's chasing you, however, we didn't manage to get to the visuals for that, so you just need to imagine there's a pool of oil on the ground when you use it! :D
Thank you for playing and we are glad you enjoyed it! <3
