What's a top quality oil filter that can replace the Amsoil?

[FlyingTexan]

I've been running Amsoil filters on my LMM Duramax but both the 15k and 25k extended drain filters are out of stock. Going to do a run from Texas to Moab and back towing my Grenadier and will do a change before and after. What compares in quality? They were claiming 99% at 20 micron.

Thanks!

Carquest Extended Performance or STP Maximum Performance. Just make sure the STP isn't old stock made by Champ labs.

Premium Guard never disappoints.

Out of business, so only possible old stock available.

Any PGI-made 10k or 25k unit, or the Walmart Mobil 1 oils in a pinch.

I’d look at fleet guard stratopore, but I haven’t had a diesel in years so unsure if they are top shelf anymore.

What ever you decide, make sure it is suitable for diesel use.

I’ll add the new PGI made Napa Platinum.
25k 99%@20.

Did you not see all the Champion labs drama?
The pgi filters are way better. Doing something like 80% at 5 micron.
We're almost back to having OG fram titanium level filters again.

The 2 main things that make it a diesel oil filter are size and usually a higher bypass psid, usually double to 3x that of a typical pcmo filter.
