Oil filter Fram or AC DELCO

AC Delco OEM filter is all I have used on my GM trucks in a long time.

Fram FE9688 for my WRX and BRZ too. I’m tempted to run two oil changes to one filter change as the filter says it’s good up to 25,000 miles.

I also use an ACDelco filter (blasphemy, I know).

Ok... so as a DIY mechanic, how tight am I SUPPOSED to tighten oil filters? The box says 1 turn after gasket contact, so that's what I do. It gets pretty tight by the end of a full turn, but I'm still able to do it with my hand (so long as it has one of those rubber grip coated bottoms, like the Fram Tough-Guard). I never have to use a wrench to get it to that point, but it takes about all my hand grip strength to do so. Taking them off is usually requiring a strap wrench, and sometimes it dents/crushes the casing.

I got an ACdelco oil filter for a 07 classic GMC duramax and right before installing it I noticed the threads were stripped off and there were big chunks metal shavings clipped off inside it.

I’ve worked on Subarus for over 20 years now and almost every blowed engine has a fram oil filter on it. Easily 75%

Using a cheap (fram) oil filter is a recipe for disaster, because those filters fail internally, and either go into bypass mode, or the internals of the filter grenade, and go directly into the crankshaft bearings.

Stay away from fram as the name is just ruined in many peoples eyes. I wouldn't buy something for good money with fram on it.

Fram Air filters: Their OEM filters are the absolutely best while the exact same filters with a "Fram" label are manufacturing rejects. Kinked pleats, misaligned bracing screen, holes in the gasket, missing glue, etc.

Fram Oil filters: Nope. Few pleats and not very strong. You can find lots of test and teardown videos. I've had past problems with the gasket swelling so badly that the filter has to be torched off.
