From what research I have done up to this point I have always been using the Fram Ultra. I change my oil every 2,000 miles but I want my new motor to stay as clean as possible inside. I was watching a video someone did on filters and here is a snippet from it.
Don't confuse engine cleanliness with filtration effects relative to wear control. Two different topics.
Most any lube commonly used has a DI (detergent/inhibitor) as part of the additive package. This includes chemicals (various; depending on brands, etc) that have two functions:
- essentially cleaning what already exists
- prohibiting the accumulation by holding what is created and cleaned in suspension
The filter's job is to grab particulate. We commonly accept 20um as the threshold for efficiency ratings, so that a common frame of reference is used to compare/contrast performance. However, most "damage" is done to engine parts by particles 5-15um in size. While most FF filters can catch some of that stuff, it's not really that effective, especially towards the low end.
What most folks don't know is that "dirty oil" is what appears when two things accumulate; soot and oxidation byproducts.
Soot starts out super-duper small; often around 40nm in size or so. (average approximation; see inserts below) That's nano-meters, not micro-meters. Soot would have to grow 100x larger, via agglomeration, to just get to 4um. Soot amalgamates; it co-joins with other soot particles. The "inhibitor" part of the additive package is designed to prevent soot from doing this. Over time, the add pack gets overwhelmed, but that isn't going to be a problem at 2k miles of use. At 20k miles, it may be of concern for some lubes. At 2k miles, it's just not an issue as long as a decent well-formulated oil is used.
Oxidation byproducts come in varying sizes, but are typically the result of two things interacting with the lube; heat and time. If your engine oil is getting too hot for too long, it can be a problem. The only way to know for sure is to take a sample of virgin oil and get an oxidation value, then run it for X miles and take another sample.
However ...
Given that you are using a top quality lube, and your OCI is 2k miles, then NONE OF THAT ABOVE IS IN PLAY !!!
Your oil is not going to degrade fast enough in 2k miles to have any substantial concern about soot levels, oxidation byproducts, etc. There's not going to be anything large enough in size, or large enough in quantity, to have any bearing on "cleanliness" relative to filtration. And I really mean it ... no over-the-counter full-flow filter is going to make a hoot's worth of difference in 2k miles regarding how "clean" your engine is going to be, given the lube and OCI you've chosen. The oil you've selected is very heat-stable. And the 2k mile OCI is going to flush out the tiny soot well before it ever becomes large enough to be caught by a filter.
If you're concerned about wear, then any decent filter which is >95% efficient at 20um is going to be fine.
