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

I used Liquimoly 5w-30 when I was NA, and still use liquimoly 5w-50 since boost. A little pricey ($120) for 10qts but worth it. Oil filter, just a ford performance filter. Pretty much any auto store will have them or a comparable brand in stock. When I was NA I’d do oil changes every 3k miles or sooner depending on how hard I drove it. Now with boost the max I go is 2k miles. Normally 1k-1.5k since I drive it hard and run e85.

Pros: worth the price
Cons: pricey

Rating 1.0

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
