Oil filter AC DELCO or OEM Mazda

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

I've taken to buying made in japan mazda rx8 filters for my 2015 impreza.

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

The Mazda filter has a higher capacity and larger design compared to the OEM Subaru filter. So, it will hang down slightly lower than OEM. The anti-drain back pressure seems to be similar, but I have never verified myself. I ran this filter on my 2005 Impreza WRX STi for a few years.

I’d high recommend doing an oil change with 10w30, putting on a factory oil filter (they’re about $10 at the dealer and come with a crush washer), and seeing how it behaves then. I recommend factory filters because for some very odd reason, I had less (or no) lifter tick when I used factory filters vs. aftermarket.

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

I went through the same thing, I believe the part number that they gave you is the made in Mexico Mazda value oil filter. It worked on my 2.5 NA. Though in my opinion, the quality of the filter is subpar compared to the OEM made in Thailand filters.

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.
