It wasn't a danger for a car's air intake to take in air mixed with exhaust from other vehicles, so we paid a Chinese lab millions of dollars to invent exhaust that is harmful to other cars when their intakes draw air mixed with said exhaust. Now you MUST use our experimental oil and so must every car in the world. Otherwise, every car in the world could stop working all at once. Science. Remember, my oil protects your car and your oil protects my car, and forget that part I said about the Chinese lab, not important.
