I’ve got a 2013 3.5 eb and I change my oil every 4k miles. I do my own changes and use Mobil 1 full synthetic 5w30 with a Mobil 1 oil filter.

Mileage: 6437 km

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

AcDelco filters and Mobil 1 filters are always good options to pick from. Don't get the 4 dollar Fram, please.

Pros: good filter options

Cons: cheap Fram filter

Vehicle: Chevrolet Camaro

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

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

I got denied an engine replacement from Hyundai/Kia in 2017 because of a Mobil1 oil filter in Canada and lost my appeal as well.

Cons: denied engine replacement

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
