Oil filter K&N or STP

Amsoil and Subaru filters. Other vehicles with horrible oil filter locations I use K&N because I can use a socket to pop them off.

I'm trying out that Rotella T6 5W-40 some of y'all talk about. Just snagged it off Amazon.

I also use K&N filters cause they've got a 1" nut welded on top.

DIY 7500mi interval engine oil using 5qt bottle of Mobil1 0w-20 fuel economy oil (takes the whole thing), a K&N HP-1008 filter (why, because it's so easy to wrench off every time), and a new 9956-41-400 aluminum washer.

I’ve been using K&N air and oil filters in mine for ten years. I run nothing else and will always run K&N. I’m happy with mine. Oil filter number HP1008. I would recommend. The one inch nut on top is often very helpful getting the filter out. I also run K&N oil and air filters in every vehicle I’ve ever owned. There is a noticeable difference in throttle response for the air filter, but I’ve never seen a difference good or bad in the oil filters.

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 also noticed it seems like it made more noise with a K&N oil filter vs Mobil 1 filter.

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.

Most cars in my house get cheap bulk ordered filters off RockAuto. Except the STI, that one has been getting K&N and soon switching to Wix. I’d never allow the oem trash cardboard filter near my car.
