Oil filter STP or OEM Mazda
I've taken to buying made in japan mazda rx8 filters for my 2015 impreza.
Vehicle:
Subaru Impreza
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.
Pros: higher capacity, larger design
Cons: hangs down slightly lower
Vehicle:
Subaru Impreza WRX
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.
Pros: less lifter tick
Cons: aftermarket filter lifter tick
Vehicle:
Mazda
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.
In my Turbo, I use what many consider the best oil for gdi engines, pennzoil ultra platinum 5w/30 with the oem mazda filter. Although some aftermarket filters have better filter media, none meet the 22 psi bypass valve specs on the turbo engine.
Pros: best oil for gdi engines
Cons: tiny filter
Vehicle:
Mazda

Since I change my oil every 3,500 miles, the OEM is the best choice.
Pros: best choice
Vehicle:
Mazda
Mileage: 5632 km
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.
Pros: worked on engine
Cons: subpar quality
Vehicle:
Mazda 3
Dont buy a Stp, had my oil changed on my 09 Legacy, a few days later I notice a drip and the usual burning smell while driving . Took It back to mechanic and they said there was a dot on filter so they swapped It out. Burning smell still there but leak was not seen, so I bought a Purolator and changed It myself now no problems.
Cons: oil leak, burning smell
Vehicle:
Subaru Legacy
My son went to a local shop who used STP/Fram/K&N and collapsed the material inside the housing, and the motor gave him fits and lights.
Cons: collapsed material, caused engine problems
Vehicle:
Volkswagen Tiguan
