Of the 2 filters, oil and air, oil filter is much less critical. Any oil filter, OCOD included, can be used for 10-15k miles in a clean engine without problem.
The filter manufactures want you to believe that the FCI is 3-5k miles for low to mid range filters, above that they want you to buy their top of the line filter at much higher cost, that is their profit is.
Even the lowest cost filter can hold about 6-7 grams of contaminants, shred metals and dirt, if your engine generates that much metals in 15k miles, it is in dying mode, no filter will keep it alive.
Thank you! You answered about every question I had in a few sentences.
