2017 Chevrolet Express 3500 6.0L LY6 159k miles

out/off: 5 quarts Valvoline Restore and Protect and 1 quart HPL Engine Cleaner 30 with Carquest Premium 84502

in/on: 6 quarts HPL PCEO 5w-40 with Carquest Extended Protection P84502

looks great as always, so hard to beat the carquest premium filter, hope these extended protections have the same great run.

How much of that carbon gunk in the filter can do we suppose became detached from the media only because the filter was being man-handled?

I'm just wondering how much free-floating gunk there might normally be in a filter canister when an engine is started, which might then get pumped through the bypass valve on a cold start.

I don't think the debris came out of the media and went to the dome end from handling the filter. This filter is probably mounted with dome down. Debris collecting in the dome end on a filter with the dome down is why Ford put the bypass valve on the base plate end.

That's a great looking filter.

Looks like a stout filter. Thanks for the photos.

Great filter, and it looks like the Valvoline Restore and Protect is putting in some serious work judging by the residue in the dome end. I can't wait to see what the dome looks like on the EP filter when you've put in an OCI on the HPL.

I love that reddish hue that the alkylated diphenylamines can induce.
