My neighbor found this in his car and wondered if I knew what it was for. I did not, thought I would post it and see if anyone knew.

If it flew out from the undercarriage and poked a hole in the oil pan, it could be the most expensive oil filter pliers in the world

They work good in tight places. Only good for removing since they usually damage the filter.
 
easier to use than a stupid can or strap wrench to take the filter off. More leverage too. Filter destroyer....

fixed it for ya

3/4 to 1 full turn after gasket contacts base, even if that means using a filter wrench. Not a filter destroyer wrench, obviously. Some filters even have an illustration on the side, and handy numbered reference points every 90°.
Around 1990, I had an old timer for an oil customer, who has since passed away. He always insisted "hand tight." Our filters were made by Purolator, because Pennzoil owned them at the time. He installed one of our filters on a 302 Ford, which leaked, and the engine blew. He put in a claim, and our tech people tested the filter to 100 PSI. The claim was denied, because the filter didn't leak. The failure was blamed on incorrect installation. I lost the account, but got it back a year or so later, but oil only.
Moral of the story: If you don't crank that sucker down a full turn, don't blame the filter when it leaks at the gasket.

i like to use these to remove them, gets you in tight spots since you can put as long an extension on as you need
i like to take mine apart and put a bunch of axle grease on the gears so the fingers dont open as you try to put it on

3/4 -1 turn past gasket contact is pretty tight. you cant usually get that with a greasy hand unless its a POS Fram ultra guard "grip tape" model.
 
Also good for pool filter pipe remover or jar opener and the larger radiator hoses.
 
I drive a flat head screw driver through the filter and twist em off when they get stuck.

I worked for a mechanic for awhile that had the same thing happen. He use to just hand tighten filters until he had one back off and blow a Diesel engine. He ended up buying and installing a new engine on his dime. After that he always put em on finger tight plus 1/4 turn.
