Oil filter AC DELCO or OEM FORD

I will never use any oil filter that is not OE/OEM.

AC Delco in the D-max.

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.

Plus I've been told its a better filter typically from the dealer.

My XJ channels its ww2 roots with Ford diesel oil and an FL-1A filter.

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

when I did the first oil change on my car I removed an aftermarket Filter. The OEM filter was about 1/3 larger, and weighed the same as the aftermarket filter full of oil. Just makes me wonder how much more there is inside the OEM filter.

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

For oil filters I feel like the ACDelco filters are pretty low quality and there are many better options. Mobil and K&N oil filters are available at Walmart for $10-15, made in USA, and seem to be much better quality.
