I've got the most recent one from our 1500 in the basement, haven't gotten around to cutting it yet. We have 2,613 engine hours on it, 418 idle hours. It does a lot of short tripping in-town.
Amsoil EA15K50 Cut Open 5511miles - HPL PCMO
- Thread starter racer12306
- Start date
Time will tell, however, I'm curious if what I'm seeing is what the Amsoil rep was referring to in response to my inquiry a few months ago...
Were the specks hard or soft?

I wonder how they are determining it is the result of MDS and not just the HEMI being a dirty running engine? Also, worth noting, this only impacts the small filter, the EaO11 (FL820S size) that's on some of them was not included in the TSB.
GM's LSx family engines were also included, since they call for the same filter.
I'd tend to say they're hard. Definitely not squishy.
Do the LS engines have an MDS system?
If you're running an OEM filter maybe it's less efficient & this Amsoil is more efficient at trapping soot. That could be why you're not seeing any debris.
OP try running this filter out a bit longer. I think you've concluded that so... Thanks for posting this Amsoil filter.
The more likely case is the PP was leaving behind a small amount of piston deposits without much cleaning action (as common API oils aren't formulated to clean), and the HPL is cleaning up those deposits. Hence, carbon deposits now showing in the filter.
Definitely wouldn't surprise me, however, it certainly isn't as dramatic as others have shown.

Yep, they have what's called "AFM" but they are also direct injected, which the HEMI isn't, which makes up for any inherently cleaner combustion characteristics, as GDI creates soot.
With Penn Plat, it wouldn't use any oil until the last couple thousand miles of the OCI (10k). Maybe this is where it was going lol
I'll be curious to see if HPL does not consume at all over this interval.
I believe the AFM is Active fuel management if I read it correctly. Maybe I’m wrong. Thanks OVERKILL for the info on the HEMIS

Yep, that's what AFM stands for. It's essentially GM's version of MDS, but they have a crappier lifter design, lol.I believe the AFM is Active fuel management if I read it correctly. Maybe I’m wrong. Thanks OVERKILL for the info on the HEMIS
Very true. Thank You sir
Little off-topic ... but I was under the impression that DI was suppose to give better combustion and power output, yet it creates more soot. I've seen the tail pipes of DI cars and they are way dirtier than compared to my port injected cars. And if DI creates more soot I would assume that the tailpipe emissions are also higher. DI almost seems backwards from port injection in terms of soot and emissions.
When I compare the tailpipe of my 2021 Duramax and the tail pipe of a modern DI car, the modern DI tailpipe has a nice thick coating of black soot, while my Duramax is clean and still shows bare metal after 40,000 miles.Little off-topic ... but I was under the impression that DI was suppose to give better combustion and power output, yet it creates more soot.

I believe it's just a matter of time until gasoline powered cars in the US have GPFs (Gasoline Particulate Filters), just like diesel vehicles have DPFs (Diesel Particulate Filters).
Great idea! Good hate driving in the mountains following a DI car up an incline. Stinks like hell and burns my nose. Can’t be good!
