Along the side of the oil fill pipe is some light brown foamy stuff. I made the assumption this was foaming oil. If I was seeing this in a water cooled engine oil, I would suspect water or coolant mixing with oil. So, because this foaming is pretty minor, I changed to Mobil 1. Foaming is pretty much down but so is my tendency to drive up to and over 5k.

Any thoughts? Others have this stuff? Anyone worried?

Thanks.
