Hey a bear!
I think you misread the Mobil document. I read it to say the MOBIL 1 (brand) 15-micron filter meaning 15-mic absolute.
Regarding George Morrison, I thought he worked for a distributor that sells Mobil products. I'll go find his sig to get straight on that.
OilGuard went on the record saying that their filter will not remove additives. I am not technically qualified to confirm or deny this. But, other than from the product seller and advertiser- I have seen no other statement to support this.
I do know with certainty that additives suspend contaminants- so in my mind, logic tells me that if the contaminants are stopped by a 1-mic filter, at least SOME of the additive gets stopped there too.
BTW- I haven't said the by-pass filter doesn't work, just that it's overkill for the majority of us.
If it gives you peace-of-mind, that adds value.
