You'll often see numbers like 5W-30 or 10W-40 on the bottle. What do these numbers mean? The first number (with the 'W' for Winter) indicates how the oil behaves in cold temperatures, while the second number indicates its behavior at high temperatures.

For the 2017 GMC Acadia Limited, General Motors typically recommends using SAE 5W-30 oil. This viscosity is designed to provide excellent lubrication and protection for the engine in a variety of operating conditions. Using the recommended viscosity ensures that the oil can flow properly to all engine parts, even when it's cold outside, and maintain its protective properties when the engine is hot.

It’s crucial to adhere to the manufacturer's recommendation because using a different viscosity can affect your engine's performance and longevity. For instance, using a thicker oil than recommended might cause increased resistance and reduce fuel economy, while a thinner oil might not provide adequate protection at high temperatures. Always double-check your owner's manual or consult with a trusted mechanic to confirm the correct viscosity for your specific vehicle.

Synthetic vs. Conventional Oil

Another critical decision is whether to use synthetic or conventional oil. Conventional oil is derived directly from crude oil and is the more traditional option. Synthetic oil, on the other hand, undergoes more extensive refining processes to improve its quality, stability, and performance. Synthetic oils are engineered to provide better protection against wear, resist breakdown at high temperatures, and maintain their viscosity over longer periods.
