Oil filter Bosch or OEM Mazda
I've taken to buying made in japan mazda rx8 filters for my 2015 impreza.
I buy Bosch filters through Rock Auto and oil during the Fleet Farm Black Friday rebate sale so my oil changes cost less than $10.
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.
The Euro oil (which I seriously doubt Valvoline used) is about $30 for a 5q jug + $10 for an extra quart, and a Bosch filter about $15.
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.
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 tried to buy a filter, a bosch is a decent choice, but I wasn't able to find it, or I should import it for 100 sar ( which is expensive, most filter sold for 20 to 50 sar where I live - saudi arabia -)
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.
The current Bosch 3323 oil filters are now made in Mexico and filter quality has decreased. I don't use the current Mexico made Bosch - I cut one open and it was a bit different than US made older ones.
Bosch Filter verbaut, hat sich unten die Dichtung am Filter abgelöst und den Ölkanal im Filtergehäuse zu gemacht ???????? kommt also nicht nur bei „billigfiltern“ vor sondern auch bei den nahmhaften Herstellern…
