Nice tool. I had to use an air chisel before (no, I didn't put it on). Oil filters that are on too tight (or the people who put them that way) is a pet peeve of mine.
Similar concept. Same issue had a stuck oil filter on my truck, tried several types of filter wrenches, ended up bending the filter so nothing could grip it well. Tried the screwdriver and it just cut it in half. Tried using a chisel on the filter holes to push it off, no dice. Ended up making the pictured tool. Still have it somewhere
The reason I put my filters on pretty tight is because somebody loosened the oil filter on my brothers car once while he was at a bar. At night with the tunes on you don't notice gauges or knocks. I don't know why the idiot light didn't come on sooner but the engine was toast. I always figured if somebody was going to try that trick on me he will have to have a good grip. Sometimes there is a method to the madness.
Yeah, I hate having to fight a filter but when I have to I use a nylon strap oil filter wrench. It tightens around the filter and squeeze the heck out of it until it finely comes off. I'll never go at with the old screwdriver trick.
Have had the oil filter adaper bace bolt come lose and drop down and catch one of the holes in the filter, would only turne a little each way. Finly after cutting the filter away, a day on my back side ,, i got where i could see some thing sticking down,pushed it back up and the rest of filter came right off. Check them their bolts for tightness.Maybe
I broke down and bought a pair of filter pliers two years ago. So far, I have not encountered anything that they can not handle.
Only issue with filter pliers is I cannot see them fitting up between the headers and engine to get at the oil filter on my Camaro. Would probably be fine for my other cars though.
I had to tie a strap around one once, used a screw driver to get the strap extremely tight, and had some one else tug at the strap. took forever, but got it done.
