No, not that I can tell and I have the last 80,000 miles of fuel economy records.
Yes, every 5k, except the last filter which was almost 10k. I'm switching the Fram out for a Baldwin this weekend. The Fram only has 5k, but I don't trust Ultras after my previous findings.
I'm not sure where you are finding the 21k miles for a filter, maybe from my first OCI with HPL? I should have changed that filter much sooner.
The Fe wear rate in the last 5k miles is around 3 times higher than in the first 28k miles. Aluminum is up significantly as well. I'd interpret this as a condemnation point, especially since Fe/mile usually trends down over an OCI (which probably has more to do with the iron getting filtered out or ending up in deposits than the actual wear rate). So actual wear may have been more than 3x higher.
It'll be interesting to see how well the oil holds up with less efficient filtration (assuming the Baldwin is the typical 99% at 40 micron). I've seen a study that suggested that more efficient filtration can reduce the oxidation rate of the oil, and since this is what seems to condemn the oil in your case, maybe it would have a noticeable effect.
Baldwin can be hard to find info on - here’s one a while back
i may have missed it in previous posts, but why not a fram endurance?
Baldwin publishes micron ratings for most individual filters. Most commonly, they are 99% at 40 micron, 50% at 18 micron. FRAM claims 99% at 20 micron for the Ultra based on a few reference models, though in a recent inquiry to them posted on this site, FRAM claimed "98% at 20-30 micron". The FRAM should be quite a bit more efficient than the Baldwin.
I'm having a hard time talking myself into using Fram again:
but, we know that the endurance isn’t actually constructed by fram and it’s the closest to the og ultra’s efficiency. just a point, i know baldwin makes a quality filter and we run them on our detroits in the big boat.
I missed that, who makes the Endurance and do they also make the cartridge filters?
i cannot speak for the cartridge filter but if you look at one in the box you will be able to see if it’s the same media as the spin on. the endurance is made by champion labs and is the same filter as the amsoil and royal purple
here is the comparison to the amsoil. the efficiency can also be found in andrew’s thread on his filter testing at ascent.
But there was also this response from Fram when I contacted them and asked about specific filter models. A statement like "90% at 20-30 microns" can't be for any specific filter, it was probably a blanket statement to cover the whole line of models.
Champ is owned by first brands I.e FRAM. May god strike me down if I’m wrong
Part of the reason being is it's not direct injection or boosted, and when you get one of these ultra high quality oils that isn't restricted with Dexos /cost you can really open up the can of goodies and these results are testimony to that. Great pictures! Did you break you arm doing cartwheels and such over the impressive results because I would have
