What i do is changed oil, oil filter and fuel filter for peace of mind every 5,000 kms. Only VIC is widely distributed that is good enough. Bosch also has poor distribution in the provinces kasi.

I also installed OCC to ensure cleaner turbo and prevent dirty oil and soot from coming back to the engine.

What i don't understand is why OEM oil filters perform poorly? Any tech guys here from one of the car manufacturers care to enlighten us?
