Which oil filter?

Who’s using the Fram XG10575 Ultra Synthetic oil filter? And what do you think of it? 

The Fram XG series has a Beta of 20  or 95% efficient: 

 

Some ISO 4548-12 comparisons: 

 

WIX/NAPA 95% 

AC-Delco 95.4%

Purolator Red 96.5%

AMSOIL Ea  97.5%.

Royal Purple 97.5%

Purolator Pure 99.0%

 

From an filtering efficiency standpoint it is that same as the WIX/NAPA

 

While it may seem no big deal that there is only a 4% spread from worst to best on this list consider that the Pure One is 95% efficient at 8 micron. Same as the WIX is at 20 micron. The WIX is 50% efficient at 6 micron while the Purolator is about 80% at 6 micron. They do not publish on the box the entire sequence only the 20 micron numbers. 

 

From a construction stand point you will have to ask others. Lot's of talk on that topic.

I got the newest version of the XG10575 and it’s rated 99% at 20 microns, better than the OEM filter. They also increased the bypass pressure to meet our requirements. The new bypass pressure is 16-28psi (22psi is smack in the middle).

The Ultra is and always has been 99+ @ 20 and 94% @ 10. It’s a great filter, readily available everywhere and for every application. I use them on pretty much everything. Some clowns lump them in with the “orange can bad” but they have nothing in common with the Extra Guards.

I had to dig to find that information but I see it. I had the numbers for the UG series. Sorry about that. More information is always better. 

 

Revised list then. 

 

 ISO 4548-12 comparisons: 

 

Fram UG 95% 

WIX/NAPA 95% 

AC-Delco 95.4%

Purolator Red 96.5%

AMSOIL Ea  97.5%.

Royal Purple 97.5%

Fram XG 99%

Purolator Pure 99%

 

You might think I'm picking fly poop out of a pepper shaker but when they list efficiency in WHOLE numbers it is often a rounding. That is there is a difference between 99% and 99.0% And marketing isn't often precise about the rules for rounding either. When it gets the close asking the manufacture for the entire ISO 4548-12 report may prove worthwhile. Why it matters. The last four Beta ratios on this chart could all read 99% eff on a filter box or on a web site. 

 

 

 

One filter that say's 99% has a Beta of 75. Of 1 million particles feed to it 13,333 will make it through the filter

Another filter that says 99% has a Beta of 100. Of 1 million particles 10,000 will make it through the filter. 

They both say 99% @ 20 micron and yet the oil from the second filter is 33% cleaner. 

 

When I asked for the report from Purolator for the Pure One I got the entire report: (On their website it says 99% 2 20 micron)

 

>5 micron = B2 50%

5 micron = B4.8 79.2%

8 micron = B20 95.0%

10 micron = B50 98.0%

11.4 micron = B100 99.0%

13 micron = B200 99.5%

15 micron = B1000 99.9%

20 micron = B1000 99.9%

 

Looks like they go to the school of under promise and over deliver. Plot this in Excel. It's an eye opener to how a filter works. It isn't linear.

In the video it says 99% at 20 micron.

94% at 10 micron isn't mentioned but seems reasonable given other data I've seen. 

I'm convinced

It's added to my personal use list as a secondary supplier. 

 

Here's one of those times you guys say I never have.

About midway through the article, their “technical training manager” gives the 94% @ 10 micron figure, so I’ve been running with it.

Cut one open, you’ll like what you see.

Good read. I smiled when in the last paragraph I see mentioned David Staley and the GM wear study. There is an SAE paper on that study I use as an Oil Bible. That study however showed that the 5 to 10 micron range the most damaging. There are a host of rubbing surfaces in a motor with films under 5 micron. Cam and roller, ring and cylinder, rocker and trunnion. Roller and tip. Vane and case. Chain pins and rollers. Piston trust side and wall...etc. 

 

I like most of what I see with the online Ultra Guard filters cut open....except for the actual bypass spring and once seeing this the lift 'range' then made sense. This AMSOIL filter exploded view shows the same spring type as in the Ultra Guard. A formed piece of spring steel. In precise thus the 16-28 psig range. 

 

 

The Purolator spring is a compression spring like below thus 22 psi. Such springs have a predictable rate.  Thus a point instead of a range.  

 

Still, it will remain on my list. Other than the spring difference the construction is solid and ratings in the top of the group. No reason not to use it. Next time I replenish my supply I compare prices.

I just run a Motorguard filter element , its cheap tech pre-WW2 era, and cleans down to 1/10 micron. they used these back in the 60-70's on old vw's  look it up on amazon, cost about $85
