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

I had the same code popping up onky after redlining. I had 2 months prior, replaced the oil filter housing on my atlas 21' 2.0t and vw passat 15' 1.8t with the metal one... off brand from amazon but works well on the atlas, so no issues, EPC would be nonstop until i turned off the car and back on. Switched the housing back to stock with a new filter and BOOM. Problem literally solved.

Pros: problem literally solved
Cons: EPC would be nonstop
Vehicle: Volkswagen

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
