ct6 can use 5w30 engine oil. The Cadillac CT6 2.0T engine uses engine oil with the specification DEXOS1-0W20, while the 3.0T engine uses DEXOS1-5W30. 5w30 is the grade of the engine oil. Below is an introduction to it: 1. W stands for winter. 2. The number before W is 5. The smaller the number, the greater the viscosity of the engine oil at low temperatures. 3. The number after W is 30, which refers to the viscosity at 100°C. The larger the number, the higher the viscosity of the engine oil and the stronger its ability to withstand high temperatures.
