Personally I like K&N filters, they come with a nut welded to them so you can use a normal wrench instead of a filter wrench. Gotta be careful not to over tighten them though

Pros: nut welded to them

Cons: careful not over tighten

Vehicle: Subaru

I have a kn 1 on my truck and winter is about every 1k miles I empty it. Its the 6oz canister and usually about half full. From may till like October I dont even have to look in it because it doesnt get more than an oz of oil build up in it. But man winter time with the condensation sucks.

Pros: little oil build up

Cons: condensation sucks

Mileage: 1000 km

Always use BMW genuine oil or Liqui Moly, along with BMW OEM M oil filters, which are made in Austria and feature an ultra-fine mesh for superior filtering.

Pros: superior filtering

That won’t happen if you were using a K&N oil filter. All these cheap brand filters are not sturdy and will collapse when you’re trying to take them off when stuck… either The Black K&N select filter or the white Premium filter will avoid this problem from happening…

Pros: sturdy, avoids collapsing

Cons: cheap filters collapse

Not sure about mobil1 filters, but stay away from K&N oil filters. I've just used one for an oil flush after extensive maintenance work, and after just 100 km it had collapsed.

Cons: collapsed after 100km

Mileage: 100 km

Something is wrong with this model. I hate dealership workshops because you get gouged.
