 You out there driving a sedan, and I come tell you when your oil low, I got some oil I use in my lawnmower, you're going to look at me like I'm crazy. Ain't nobody going to put lawnmower oil in my expensive car. Because you place value on your car, the level of oil, the synthetic oil has been processed to the degree of the value of your car. Your car won't take junk oil. Where you going? You can't be hanging around with junk oil.
