Oil filter K&N or Wix

Buy WIX, never go back.

I started using WIX/Napa Gold about 2 years ago for all our vehicles, including the German ones (BMW & VW). Have had no issues and after I learned that they were owned by Mann I stopped caring.

Wix XP for over 100k. I used to work at a NAPA auto care center and we never had issues with the Napa gold’s

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

Wix probably beats oem. They a great brand.

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.

My L5P gets better mileage than my 16 5.3. I do my own oil changes. Cost me about 80$ for full synthetic and wix filter.

I'll say the only issue I've ever encountered with Wix filters when they come into the shop (dealer) is that they seem more prone to cavitate/collapse in the center of the filter than OEM; that's it. Most of the time they are completely fine. I've yet to see an OEM filter collapse in the same way. I'm not sure if the sidewalls of the pleats are not as stiff for some reason, but yeah. That's my anecdotal experience with them over the years of oil changes.

I have a 2016 Chevy Silverado 1500 5.3L with a fresh oil change and properly torqued filter. When it gets below zero and I cold start it, my oil filter loosens itself enough to where oil leaks out when starting. I have to crawl underneath and tighten it by hand every time. This has never happened until this year.

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.
