OK I really need some help guys. I checked my oil today and i was low. So I went and bought 2 quarts of Castrol Edge 5w40 Full synth. I take the oil cap off and there is this gunk or wtf it is all over it... Its a light grey color and its about the consistency of a melting milk shake. The car is running fine I have no issues with performance or anything. no weird noises or anything it only has 28555 miles on it. Please help I really don't know what to do or how to get rid of this should I Sea-foam it this weekend or pick some up tomorrow let it run and change the oil this weekend?
