Drained the oil catch can today when I did an oil change on my mustang. I took out Pennzoil ultra and put in Royal Purple. This 1/2 cup of coffee colored oily water gas mixture was from about 4,000 miles of driving. The picture of the oil filter is so you know what color the actual oil was coming from the car. For the 4,000 miles since I drained the catch can this car has seen 2 40 mile round trip highway drives a week, a 1000 mile round trip highway drive to Florida, and the rest being mostly 5-10 mile trips around town.
