Oil filter AC DELCO or Castrol

Get the afm tuned out. And use ONLY full synthetic oil and a ac Delco filter. Mine has 232,000 and has been super reliable and still runs like new

7 Qts. Mobil-1 5W-30 Standard Full Synthetic, 500 mL bottle Rislone Engine Treatment, ACDelco PF61E. That's what I've used for all of my oil changes I've done on my 2008 and I've had absolutely no problems.

OEM AC Delco

I use Pennzoil 0W-30 Euro Platinum, and a Castrol CAS3593 filter every time, and change my oil every 6000kms which is about 3728 miles. I have heard good things about the efficiency of the Castrol filters.

Use full synthetic Mobil one or Castrol Change every 7k miles. And the oil filter too.

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

Yes, Castrol gtx and a KN oil filter

Switched between fram and ac delco. Sticking to ac delco due to a tsb. Oil pressure issues.

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.
