Oil filter AC DELCO or MOTUL

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

Motul Oil change kit on subimods, that’s it

Motul and oem filter.

I like using motul with OEM filters but I doubt it's making much of a difference.

If I really care about the car, I use Motul and a factory filter.

Ac Delco is the obvious choice for oil n fuel filter

AC Delco oil filters are now all made in China (but they won't confirm nor deny this), so they have a single package for all markets they serve.

WIX. AC Delco used to be my go to for gm vehicles but some years back they switched out metal parts for plastic and the filters started to have a higher failure rate.

I got an ACdelco oil filter for a 07 classic GMC duramax and right before installing it I noticed the threads were stripped off and there were big chunks metal shavings clipped off inside it.
