K&N now offers oil

It probably contains elevated levels of silicon antifoaming agents. Then you can't tell that it is their air filter causing the high silicon on your UOA.

Also easy to hide when there isn't any elevated SiO2 in your oil using a K&N to start with.

From my experience really really good. Haven’t had any issues with them. I know people who only use them on their cars and have had no issues.

Same can be said about just about any OEM filter, though. And many cheap aftermarkets. Just depends on who you talk to, really.

I pass on their filters, I'll pass on their oil too.

k&n air filter oil is great stuff.
I would give their motor oil a chance.
Who wants to bet it will have a ton a silicone antifoaming addtives for reasons.

5w30, 0w20 or 5w20 all Dexos 1 Gen 3. You pay your money and you take your silicon antifoaming add pack.
