AMSOIL EAO17 09/10/24…….its a leaker :-(

hopefully someone at Amsoil cracks down on the quality issues. If they just "trust" Champ Labs to make a quality product with the Amsoil brand on it, then they are just being too lax with a supplier.
100% agree.

I purchased a large quantity of Amsoil Filters ( here in Aus its a HUGE cost !!) because i have 100% trust and faith in the Amsoil oil,s i use .
I purchased the Amsoil filters "thinking" i was getting the same level of quality and performance as the "Oil" product"
I was shocked when i started reading about filter issues and then after my own , personal analysis that confirmed the horrific quality control i was angry that Amsoil would allow a product bearing their name to continue to be sold .

As I've said previously, AMSOIL commands a premium price for what is sold as a premium product. This filter fiasco is a black eye and needed to be addressed months ago. They need to court Fleetguard or Donaldson, companies who have a reputation for producing quality oil filters, to solve this. Anything less is just damage control, nobody should trust anything produced by First Brands at this point.

Does Fleetguard or Donaldson actually private label for anybody else? I am not talking a couple SKU's but an entire vehicle catalog coverage?
 
The new PGI 20k filter would be a great match for Amsoil!
99.5% at 25 microns isn't as good as the EaO, advertised at 99% at 20 microns (and the OG Ultra was higher than that still). I'd be confident that Fleetguard or Donaldson could produce an EaO that's similar in performance to the OG Ultra, which is what I think the filter should perform like.

I agree but with QC problems the current Ultra and EaO are not filtering to their potential. I’d love to see Donaldson high efficiency passenger car filters!
 
I definitely assumed Amsoil oil filters were still Donaldson, so that’s unfortunate for myself and my clients. Brand Ranks has a couple oil filter videos - watch them and take your pic.

Thankfully, my vehicles use cartridge filters, but Amsoil still doesn’t make anything for both cars I own ;-).

Take your pick with a grain of salt. The only info that's worth going by if interested in efficiency is the ISO 4548-12 efficiency rating. This this kid of data - HERE

You’re saying the video where they purchase and use ASTM dust then test for particle size is insufficient? Did you watch their videos or are you jumping to conclusions?

I've watched them all, more than once. There has been a lot of discussion about that testing in this forum - do some searches and you'll find them. Just because they used ASTM test dust doesn't mean it's an official ISO 4548-12 efficiency test. Why does the Boss rate #3 in efficiency along side filters that have an ISO efficiency of 99% @ 20u, yet Purolator and M+H will tell you along with the official spec sheets from M+H that the official ISO 4548-12 efficiency of the Boss is 99% at 46u.

The correlation between the ISO efficiency and BR's efficiency are way off, yet people will take the BR info as some golden standard instead of the actual official ISO data. If the Boss was as good as the filters that are ISO rated at 99% @ 20u, then Ascent's official ISO 4548-12 test would show the Boss up with those other filters that showed high efficiency, as shown in the post 110 link. People buy into YT videos way to fast without knowing the other side of the story, or using some other data sources to verify their testing results.
 
Interesting.

The link you sent doesn’t help me for my cars unfortunately. I’ll keep searching…

How's that? What that graph shows is that pretty much any filter ISO efficiency rated at 99% @ 20u is going to be much more efficient, especially for particles at 20u and below, than the Boss or Wix XP. At least when that test was done. Oil filters change all the time, so it's worth seeing of the filter maker changes the efficiency claim with a filter change. Some claim that the Boss is better because of how the media looks, but if you call Purolator tomorrow they will tell you the efficiency is 99% @ 46u, just like the official spec sheet from M+H shows.
