when you have a tank, you fill it up completely with crude oil and then you take a Universal Duct and plug it into a Boiler, set it to extract with a screwdriver, it will fill up the internal buffer of the Boiler (8000mb) and then it will proceed to void the remaining 248 buckets of Crude Oil
idk if it does this for anything else, this is the only thing i experienced it on, also i'm playing on 1.12.2
