Cheapest way to remove a stuck oil filter stud

Tight engine spaces prevent wrenches from fitting, making a socket-based solution the best cheap approach. Because specialized single-use tools are too expensive, some end up just leaving the old filter attached and filling the engine with new oil.

“The problem is I don't know what the best way to remove it is cheaply. There is barely any space to fit a wrench, so a socket solution would probably work best.”source ↗

“I don't really want to spend too much money on single use tools like this, so I'm asking what y'all think is the cheapest way to remove it”source ↗
