i thought the lf3947 was supposed to be a stratapore filter. it does not say stratapore anywhere on it and it does not look like a stratapore element. different line of filter from fleetguard or possible fake?

Looks fine. How many miles and what kind of oil? Off your Ram 2500?

All signs point to a Champ Labs made filter. Champ thread end bypass design used on many M1 and FoMoCo 'factory filters'. Champ uses louvered centertube too and what I can see of yellow date code looks like Champ Labs too. Same adbv design and leaf spring design used on some Champ Labs made filters like the FoMoCo factory filters. And the stamped M on baseplate is found on some Champ made filters like STP blue.

FoMoCo Factory Filter

Can't tell you if 'all' Fleetguard are supposed to be stratapore, but apparently this one isn't. Given the choice, don't think it's fake, just a different line.

Looks like it got the job done.

That's a pretty short OCI for Synthetic if you last OCI was also Synthetic you may have already clean a lot of junk out of your engine. Were both those OCI's the same duration or close?

Definitely looks different than the strapore application for the Cummins diesel, Iíve cut mine open and the spring was coiled not the leaf spring type.

While it may not be an FG Stratopore/micro glass, IMO it looks to be a well made filter. Based on this one, I'd have no concerns about running one, in fact I'd do so with confidence.

As for the comparative appearance of particles caught, not much science to that. Mostly subjective. And at 3k mile oci/fci about what one would expect in appearance with well maintained engine. ST Synthetic and this filter easily good for 5k+ mile ocis. Your call though.

As reference Donaldson too sells another similar to topic filter line besides it's full synthetic filter line.

How odd.... never thought Fleetguard would sub out to Champ Labs?

Any guesses on what efficiency the filter media is?

One giveaway is if one inlet hole is larger. Luber Finer makes a lot of Champ Labs heavy duty filters, or Champ makes them and puts Luber Finer on the can.

No idea of efficiency. Perhaps an email to them might provide some information. Though reading their website seems a vague meets or exceeds oem specs.

As for the topic application being made by Champ Labs, for all the reasons listed in first post here, I'd put my confidence in the upper 90% that it is accurate. All of them have including but not limited to the stamped M on baseplate have been posted on this subforum in the past.

Edit. Seeing the added mention of LuberFiner, LF is noted as a Champ Labs filter brand on their website.

Yes, that is established.

But........... this is a FleetGuard -
a filter that typically costs a bit more than Luber Finer and is supposed to have media similar (or identical to) the Donaldson Synteq media.

Yes..... but these are supposed to be "Microglass" media, not paper.

It does make a difference when you think you are paying extra for Synteq media, but get paper instead.
