2008 Chevrolet express 3500 6.0L 120k
in service: 6k

out/off: 5 quarts Valvoline EP HM 5w-30 and 1 quart HPL EC30 with Purolator BOSS PBL12222

in/on: 6 quarts HPL PCEO 5w-40 with Carquest Premium 84502

i don’t even remember installing this filter its been so long. looks great as they always do minus a little extra glue

Looks good

I'm running one with a full sump of VRP, only 50k miles interval, highway miles. Good filter.

very well constructed, not great at actually filtering. 99% @>46um.

... You mean 5K intervals?

99% at 46microns is pretty bad. Not sure what the point of a pretty filter is if it can’t, well, filter?

Looks good though!

Ha!!! Yes, 5k intervals. Thanks

It looks pretty. Yes. Tests show it can hold a sustainable amount of debris, residue if there might be that sort of need.

Inefficient filters like the Boss and XP are big debris sloughers (part of why they are inefficient), which is not really the best thing to do if running a filter for long OCIs. The longer the OCI, the better it is to use a higher efficiency filter. Filters with high ISO 4548-12 efficiency ratings are filters that do not slough off debris like a lower efficiency filter.

I'd use this model. Looks good.

Both are full synthetic fibers, slippery. Maybe that’s why the PG cafi vafi many clones put paper in the glass. I think Boss uses a non glass. Boss has a very high capacity. I guess the sloughers are not doing their sloughing well. .

Doesn't matter what the Boss and XP media fibers are made of, they are inefficient at filtering and a lot of that has to do how they slough off already captured debris as the dP increases. They don't slough off debris because the fibers are "slippery". Ascent's ISO 4548-12 testing clearly showed that happening. Filters with high ISO 4848-12 efficiency don't lose much if any efficiency from debris sloughing with dP. They retain captured particles well.
