Oil filter AC DELCO or Castrol

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

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

Absolutely not. Example, I was an equipment manager at a Petroleum tank company. On our generator I tried to use several different manufacturers and the all blew the seals out because of filter material and pressure valves they used. I ended up buying OEM filters and never had a problem after that.

Castrol Edge 0w 20 with the Dexos1 and an STP gold filter done at 2k.

7500 miles religiously, including filter every time. Full synthetic 5-30 Castrol.

I buy Castrol edge and Mazda oil filter off Amazon.

RockAuto sells AC Delco oil filters for $9. AC/D dexos 5-quart for $19 and one single quart for $4.

AC Delco oil filters are now all made in China (but they won't confirm nor deny this), so they have a single package for all markets they serve.

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.

the local gm dealer here uses the cheap delco filters and they always make my oil pressure drop 10psi
