Oil filter K&N or Castrol

No complaints from my 16 STI running Pennzoil Ultra Platinum and K&N filter.

Brand is personal preference tbh.. ive seen good and bad reviews with royal purple but no evidence that its actually bad. My main 2 that i use are Delo 15W-40 Full Synthetic Heavy Duty Turbo Diesel oil and when thats sold out i run Mobil 1 Full Synthetic 15w-40. And i put a K&N oil filter every time, changing oil at 5K miles and ive had no issues using it as a daily and autocross car. Backroads racing on the weekends, roadtrips, some drifting. Got 271K miles on it and no motor issues.

I buy Castrol edge and Mazda oil filter off Amazon.

Have done many oil changes on both my Tellurides, and used K&N every-time, better quality than OEM.

My ‘11 CR-V AWD is sitting pretty at 285,000 miles and I’ve been using a combination of Valvoline MaxLife Engine Oil High Mileage Full Synthetic and K&N High Performance Oil Filter for the last 100k miles.

Valvoline High Mileage w/ K&N Gold filter, I've had no problems, and it runs smooth

Also, use the best filter you can afford and that means K&N (I hate that VW Mann 3D world junk).

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

As good as their airfilters are... their oil filters are as shite. They leak and are downright dangerous.

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.
