Tell me your top 3 oil filters for efficiency....
- Thread starter ZZman
- Start date
Purolator 1, Fram Tough Guard, and Champ XL are all excellent filters for 7500 mile oil changes
Dirt capacity is almost irrelevant, when I cut open oil filters at 200hrs or 6,000 miles they're still fairly clean.
For $13 I don't think anything beats fram synthetic endurance oil filters.
I can get down to a 2 micron "hydraulic filter" but they run around $40 or more, may not have a bypass, or be available in the thread size you're looking for, ect.

Carquest Premium 99.5%@20
Microgard Select 99%@25
Premium Guard EX 98.7%@15
All the same filter with superior build quality currently.

all made by premium guard^ they’re the best value in filtration right now with excellent efficiency to boot. i run them 12k miles in industrial fleet service.
Premium guards I've been using, lately they seem to be the best quality. And the new m1s at Walmart
Unfortunately, ISO efficiency data is severely lacking from the oil filter brands. You will get responses but there's little data to back it up. Anyways, Just use any of the brands mentioned & it'll be just fine for your 5k intervals. I like Purolator filters & they were one of the only ones providing data. If you let us know your Purolator part number, efficiency data may already be listed here already.
Some of the official date from Purolator/M+H will show why not to use some of them based on efficiency. The companies that list one or base the ISO 4548-12 efficiency on the average of 3 filter sizes is better than not listing anything, or listing just the percentage of efficiency without any corresponding micron size.
So you didn’t even answer question. Thanks for adding nothing.
Anyways my 3 are CQ premiums, PEntius PXL AND DONALDSON white can
All those are trash compared to a 2 micron wix hydraulic filter if the question is efficiency.
It kinda boils down to how much is someone willing to spend and how hard are they going to look for it.
Hydraulic oil filters don’t fit on an engine and I wouldn’t want to use one unless specs and bypass matched say a Donaldson filter.

If you’ve got a Rural King anywhere near, the new M1’s are a bit cheaper there.
What do you mean hydraulic filters don't fit on an engine?
I've got 2micron filters that are 13/16-16 thread size for doing exactly what you say can't be done.
The only difference is a higher pressure bypass, they cost more, usually at least double that of a normal oil filter and are harder to find.
I think the 10micron absolute Baldwin's were around $30 and the 2micron wix were more like $50.

I would say Fram has been the leader in aftermarket efficiency, showing the numbers and have researched, tested, and developed media. They have shown their test lab in videos, and list several filter numbers tested. You want manufacturer specs met. I wouldn’t experiment with filters not approved for the specific application.
But then there has been quality control and engineering changes with Fram.
I can’t give a top three because a lot of the efficiency data is believing words on a box or website from the people who are selling them.

Fram Endurance: maximum efficiency at letting oil get through.
Seems like there has been a change of mind about Fram and ISO 4548-12 since the "goodtimes" days.

Would you include the STP XL in this group?
Yes. But in some areas they are Champ made so inspect before purchase.
No but several filters will match them at 20 microns and for less than half the cost.
I wouldn’t hesitate to use of the filters in the PG portfolio.
There’s some duplicates and some missing but here is the PGI brand portfolio. Some may not be the extended life version.
