Oil filter K&N or AC DELCO

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.

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

RockAuto sells AC Delco oil filters for $9. AC/D dexos 5-quart for $19 and one single quart for $4.

I buy 6 quarts of Pennzoil 5w30 full synthetic and an AC Delco filter for like $38 from Walmart.

In my area I usually buy my Mobil One full synthetic at Walmart in the 5qt jug for roughly $22, use what I need (my vehicle uses litters ...) My Delco filter is like $6.

second oil change i used 0w-30 with a KN oil filter and it felt like it had more torque off the line. It could just be a placebo effect but that's what I feel.

For oil filters I feel like the ACDelco filters are pretty low quality and there are many better options. Mobil and K&N oil filters are available at Walmart for $10-15, made in USA, and seem to be much better quality.

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.
