Oil filter Bosch 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.

I buy Bosch filters through Rock Auto and oil during the Fleet Farm Black Friday rebate sale so my oil changes cost less than $10.

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

Wix probably beats oem. They a great brand.

The Euro oil (which I seriously doubt Valvoline used) is about $30 for a 5q jug + $10 for an extra quart, and a Bosch filter about $15.

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.

If you go aftermarket get WIX brand filters. I use their oil, air, and cabin filters. All of them are as good or better than OEM

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.
