What type of oil is recommended for a 1997 Chevy Suburban?

The recommended oil type for a 1997 Chevy Suburban depends heavily on the engine it has. Suburbans of that year came with several engine options (e.g., 5.7L V8, 7.4L V8). You MUST check your owner's manual. It will specify the exact oil type and viscosity recommended by the manufacturer.

However, generally speaking, for older vehicles like a 1997 Suburban, you'll likely find recommendations for:

* SAE 10W-30: This is a common viscosity grade for older vehicles and works well in a range of temperatures.

* SAE 10W-40: A slightly thicker oil, often recommended for higher mileage vehicles or hotter climates.

Crucially: The owner's manual will also specify the *oil type*, such as conventional, synthetic blend, or full synthetic. While you *can* often use a higher quality oil (synthetic blend or full synthetic) than recommended, you should *never* use a lower quality oil than recommended.

Before changing your oil, consult your owner's manual to find the correct oil type and viscosity for your specific 1997 Chevy Suburban engine. This information is critical to ensure proper engine lubrication and longevity.
