Oil filter Mahle or K&N

Engine oil: I use 10w40 in my rebuilt ABA/2H. No issues. I prefer Mahle filters.

I go for K&N. No complaints. Also, they have that nut on the end, so you can wrench it off.

I've been running Castrol 5w40 in my cars for years. Started in my '99 Beetle 2.0 and now my 1.8T GTI. I use the K&N filter but I get the one for the Passat since its larger.

I have several VW/Audi cars and I use Mahle oil filters most of the time. I've heard some horror stories about other aftermarket filters causing some problems, particularly on the water cooled Vanagons (I have one). Mahle and Mann seem like the best option.

Been doing it myself with full synthetic and k&n performance filters every 3k ever since.

K&N filters are beefier, my old VRs filters used to come out looking like that. The only filter that would withstand the vr and keep its shape was the k & n

I use K&N oil filters sometimes, a little cheaper than oem but they are quality.

I'm still running my K&N oil filter, though I've got a Mahle that I ordered along with the ABA pump.

The filter I was running was a K&N. I removed the old filter and it had totally collapsed. The oil light would come on at every stop in the first 10-15 minutes of driving. Especially in cold weather. After changing the old K&N filter that was in horrible condition, I have had no issues whatsoever.

Most cars in my house get cheap bulk ordered filters off RockAuto. Except the STI, that one has been getting K&N and soon switching to Wix. I’d never allow the oem trash cardboard filter near my car.
