    Could have had a little water in your oil, this is why quality oil costs more. I would get an oil change with an oil treatment to buffer.

    May be normal from condensation, if the vehcle only makes short trips with out reaching operating temp. If not may want to check pcv valve, keep an eye on coolant level, leaking intake take manifold gaskets can cause oil and coolant cross contamination.
