Oil filters that were improperly installed or used way too much over their limit can get stuck in the system. In this case, special tools can help take it out without damaging the filter or at least not harm the engine: - Oil pliers. These can be adjusted and used for different sizes of filters. Still, they’re usually quite bulky and don’t provide much flexibility. - Chain tongs. Regulated diameter and tight grip are great, while the latter can be lost due to oil getting on the chain. - Band wrench. Catches more area of the filter and thus can be tightened a bit harder than other tools. - Crescent wrench. While ensuring the tightest grip, such a tool is likely to tear the filter if applied too hard. - Screwdriver. That’s the last method to go with, as it’s most likely to damage the filter. Put the screwdriver inside and turn it trying to spin the filter body. If not prying the filter off, it will make the top part come apart, where a chisel can be used to remove the remnants.
