I see this Full brand oil filter is now sold at Napa through Altrom for some applications. The parent company is Siam Filter in Thailand I believe. It looks like an OEM Nissan filter. Here is our conversation and what the company had to say about their version of the Nissan filter:
My question: I am interested in an oil filter for my 2011 Nissan Altima 2.5L engine. The Full filter part number is 2ONS002. Can you tell me what the filter efficiency rating percentage is at 20 microns? Also, is the filter media cellulose, synthetic, or a combination of both? Any information would be helpful.
Their response: "Our 2-ONS002 is a long life oil filter which was designed to have similar filtration efficiency as the oem filter. Most Japanese passenger cars will have moderate filtration efficiency but rather long oil change interval. The average filtration efficiency (defined by multi pass test method) at 20 micron of our filter is approx 50%. The multi pass test method is the standard evaluation method used in filtration industry to evaluate the efficiency of filter media at each particular particle sizes. However, the general market would use the term "nominal micron" which has a slightly different definition. In such term, our filter and most Japanese oem filters would have the 20 micron efficiency (nominal) at about 90%.
For more technical understanding of the term "micron rating", please read this attached literature. I hope it is not too detailed for you. https://a.gfx.ms//pdf_57.png
With regards to your question about the media, our long life oil filter media is a blend of cellulose fiber + high percentage of synthetic fibers + thermosetting resins.
We do also produce oil filters with higher filtration efficiency exceeding the standard oem requirements. However, higher efficiency comes with higher pressure drop. So, we designed such high efficiency product to be used only for synthetic oil which has lower viscosity.
If you are interested in the high efficiency version of the oil filter, we will keep you informed. We expect this version of filters to be available in USA through the stores sometime in the near future."
They are much more forthcoming with their information than either Gohner or Nissan about anything concerning their filters.
Is this 90% at 20 microns comparable to how Fram comes up with their 95% or 99% at 20 microns? Any thoughts?
