Secondly, unless the aftermarket filter maker catalogs a oversize filter for your application, they have grounds to not honor the warranty for their filter and not cover any engine damage.
That being said, there is very little evidence in most applications that adding a oversize filter does nothing more than give a warm fuzzy placebo effect for every little extra overall oil capacity.
You, sir, are going to be in time out ... Your heresy in applying common sense and logic are out of bounds. How dare you bring forth the lack of proof and risk of warranty denial as appropriate considerations for this topic.
Do you not understand that if something is good, then it's downright Amurikan to up-size it, 'cuz more always be better! Have you not heard the resounding call of the BITOGer zealot; syns and huge filters are the only safe means of maintaining anything, and if you do not follow this mantra, your equipment will surely die, instantaneously screeching it's main bearings to a galled halt. Cannot you simply turn a blind eye to the complete lack of evidence that suggests oversized filters do nothing? Despite all theory, a total lack of credible data indicating larger filters are a boon? If one up-sized filter is "better", cannot two of them in tandem be considered "more better"? If two up-sized filters are "more better", then would not a bank of them mounted on the firewall or frame-rail be "more best"?
Further, do you not recognize the great legal power of the BITOG collective? When, in the rare event of filter failure, the BITOG elite will rise up, pool together tens-of-thousands of dollars, and pay for your legal wrangling, as well as your rental car for the 7 years of delays in court/arbitration? And the BITOG elite will also befuddle the uneducated masses with their filter rhetoric, over-riding all the expert testimony of actual filter engineers and reams of data they have at their disposal?
We eschew your logic, and supplant it with the BITOG experience of "more is always better".
For shame; woe unto you. You are to sit in the corner. Say 10 "Our Filters" and 5 "Hail Moly's" and you will be forgiven.
