What is the oil specification for Cadillac XTS?
2 Answers
The original oil specification for Cadillac XTS is Mobil 1 Silver 5W-30. The oil grade typically indicates viscosity and quality. 0W40 oil is also acceptable for Cadillac XTS. For post-maintenance oil changes, you can choose brands like Mobil, Shell, Castrol, or Total. Oil viscosity changes with temperature, so special attention should be paid to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity - 5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, resulting in smoother cold starts. The latter number represents the oil's kinematic viscosity at 100°C - higher values indicate better viscosity retention at high temperatures, which can be understood as better lubrication performance under high-temperature conditions. The oil change procedure for Cadillac XTS is as follows: Wait for the engine temperature to drop, allowing oil to drain back to the oil pan; Use a wrench to loosen the drain plug, collecting the old oil in a pan until it stops flowing. Start the engine for 30 seconds to drain oil from the main oil passages; Remove the oil filter using a special wrench; Apply oil to the seal of the new oil filter and tighten it clockwise by hand; Add new oil through the engine valve cover filler port, typically filling about three-quarters of a standard oil container; Run the engine for 5 minutes and check for leaks around the drain plug and oil filter, repairing if necessary; After stopping the engine, pull out the dipstick to verify the oil level is within the standard range.
As a Cadillac XTS owner, I recommend using 5W-30 engine oil, which I've consistently used for smooth and worry-free engine operation. This viscosity grade performs well in all weather conditions, ensuring easy cold starts in winter and maintaining protection under summer heat. Using the wrong oil grade may lead to increased fuel consumption or accelerated engine wear – definitely not worth the risk. I change my oil every 7,500 miles along with checking the compatible filter. Synthetic oil is preferable as it offers superior durability and reduces maintenance frequency. Maintaining proper car health isn't just about driving experience – it saves money long-term. Remember: always follow manufacturer recommendations and don't fall for oil-change myths.
