I've taken to buying made in japan mazda rx8 filters for my 2015 impreza.
I’ve got a 2013 3.5 eb and I change my oil every 4k miles. I do my own changes and use Mobil 1 full synthetic 5w30 with a Mobil 1 oil filter.
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.
AcDelco filters and Mobil 1 filters are always good options to pick from. Don't get the 4 dollar Fram, please.
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.
Mobil 1 filters are fine. I use them all the time in my E92 and I'm at 250k miles with ZERO engine issues. My car is used for commuting and has no modifications to it.
I chose to use Mobil1 0w16 oil and a Mobil1 oil filter ...made in Vietnam.
Mazda oil filters are good but there are aftermarket filters equal and some are better than Mazda filters. Call the independent shop and ask what oil and filter they use then research it.
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.
I got denied an engine replacement from Hyundai/Kia in 2017 because of a Mobil1 oil filter in Canada and lost my appeal as well.
