Motor Oil Has Turned Dark and Milky
After about 1100 miles of use with Mobil 1™ full synthetic, my oil turns dark and has a milky like consistency. I have consulted many of my friends who say the same happens to them. Is this a problem in Mobil 1 oils or are these just isolated incidents?
-- Ray Luevano, Copperas Cove, TX
We are not aware of this issue unless you are making multiple short trips and never fully warming up the car.  If this is the case, we recommend a 20-minute drive on a freeway or interstate to drive off excess moisture.
