Yep, been doing it that way all these years. True, you do sacrifice the bottle, but if you have a sealable drain pan, that works too ;-)A wide funnel and steady hands will do the same thing. And you’ll still have the jug to put old oil into.
Not sayin I would adopt this method. Just struck me as “interesting” for those with no funnel and pouring anxiety!! LOLBro that's just lazy. Even more so when I see all the dirtcake surrounding it.
