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

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.

Pros: good efficiency
Mileage: 6000 km
Part number: CAS3593

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

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
