I work on forklifts for a living and sometimes run into filters that the ONLY way to remove them in with a cap style filter wrench. I originally bought the metal ones but they are just not grabbing some of the filters. I will try the plastic ones, but not sure what sizes I should get. What are the common sizes on say most 4 and 6 cylinder engines? I work on any and all brands so I never know what filter I will run into. Most filters do have the shape to except a cap wrench, but I can never get the metal ones to work. I hate to buy the full master sets cause I just dont have the room for all of the un-needed extras. What size and brand should I get so I no longer have to fight this stuff laying in the dirt?
