My worst fear is a mechanical issue like the pick up tube sucking air somewhere but my first guess is that the bubbles are related to the additive. Has anyone out there had a similar experience?

I've used cera-tec and like the stuff. I doubt there is a connection and I've never seen oil foaming when I use the stuff.
