Oil filter AC DELCO or Mobil

Im using mobil 1 extended performance with the factory oil filter...so far so good.

I use 5w30 mobil 1 and mobil 1 filter thats guaranteed to 20k miles, and I change it at around 10k. No noises, runs great. Done 34k miles in 7 months.

Been using just regular t4 Rotella and AC Delco filters on all of my diesels since 2011. No complaints

Usually I get them in bulk from the dealership. Are cheaper when comparing with the aftermarket and are very good OEM filters. When I don't have one available, I use Mobil 1 M-108A and I get it from Walmart when I get the oil.

Currently running a mobil1 oil filter since they have good filtration for reasonably good flow.

After watching some tests videos on YouTube, looks like mobile 1 filters had the best filter capabilities. So I’ve been using that for years now.

Been driving STIs reliably for 20 years, and I never use oem.\n\nI use Mobil (M1-110, the longer one), or Wix.

The best oil filter is mobil 1 but there was a batch years back and could tell simply by shaking filter and would rattle.

Ac delco/delphi quality has been getting really bad. There’s a cheaper line of products that are all Chinese and then a higher level. I stopped using their oil filters when the threads were completely off for my 3800.

I changed the oil with an AC Delco PF66 filter. Turned on the car and it instantly started spewing oil. Immediately turned it off. Oil sprayed through the cracks in front grill/bumper panel on passenger side.
