What kind of oil for a 2002 Chevrolet suburban?

The recommended oil type for a 2002 Chevrolet Suburban depends on the engine it has. Suburbans of that year came with several engine options. To know for sure, you need to check your owner's manual. It will specify the exact type and weight of oil recommended by the manufacturer.

However, generally speaking, a 2002 Suburban likely calls for one of the following:

* 5W-30: This is a very common grade for many vehicles, and a good starting point if you don't know the specific engine.

* 10W-30: Also common, especially in warmer climates.

Crucially, the owner's manual will also specify whether to use conventional, synthetic blend, or full synthetic oil. The choice depends on your budget and driving conditions. Synthetic oils generally offer better performance and longevity but are more expensive.

Don't guess! Check your owner's manual. Using the incorrect oil can damage your engine. If you can't find your owner's manual, you can often find a digital copy online through the Chevrolet website or a reputable repair manual provider.
