I've seen this in 3 different oil brands now. I noticed what looked like gel blobs going in the funnel, so I stopped putting it in the engine and poured the remaining jug into an old plastic ice cream pail, sure enough small lumps. Anyway, they blended in with stirring, the oil didn't smell funny or seem different than the other oil I had, so I used it. UOA came in about identical to the last.
