Oil filter K&N or AC DELCO

Been using just regular t4 Rotella and AC Delco filters on all of my diesels since 2011. No complaints

I'd only mix in half a quart each OCI, just to keep the oil pump happy. Nonetheless, it'll be fine. My '08 3.3L Chrysler takes 5w20 & I always replace a quart with 5w30 or 0w20, depending on the season. My '06 3.8L Buick takes 5w30, I typically replace a quart with 10w30 since I live in the desert. Doing so, in combination with only using Purolator & ACDELCO (personal preference) filters & changing them every 3k as recommended, keep my engines happy with their age

Also the K&N oil filter is superior to HD’s despite the recent upgrade. The K&N has a better flow.

K&N HP1002 because it has a hex on the end that makes taking it off through the wheel well really easy. Don't even have to jack up the car, just remove the rear splash guard.

That is why I always buy a k&n filter where can just use a wrench.

I put a K&N nut topped filter on it and never had to do that again!

K&N is good but sacrifices filtration for flow for better performance.

Ac delco/delphi quality has been getting really bad. There’s a cheaper line of products that are all Chinese and then a higher level. I stopped using their oil filters when the threads were completely off for my 3800.

I changed the oil with an AC Delco PF66 filter. Turned on the car and it instantly started spewing oil. Immediately turned it off. Oil sprayed through the cracks in front grill/bumper panel on passenger side.

Previously used the k&n one and it always leaked. After 3 filters, i switched
