Cadillac uses Mobil 1 Silver 5W-30 engine oil. Here are the relevant details: 1. Engine oil, also known as motor lubricant, with a density of approximately 0.91×10³ (kg/m³), serves multiple functions such as lubrication and wear reduction, auxiliary cooling, sealing against leaks, rust and corrosion prevention, and shock absorption. It is often referred to as the 'lifeblood' of a car. 2. 10W-40 represents its SAE viscosity grade. This value indicates that the oil is a multi-grade oil. 'W' stands for WINTER, and the number preceding it denotes the oil's flow characteristics at low temperatures; a lower number means better cold-start performance. The number following 'W' indicates the oil's stability at high temperatures. 3. In extremely cold regions where temperatures drop below -29°C, SAE 0W-30 oil can be used. This viscosity grade facilitates easier cold starts for the engine in frigid conditions.
