What kind of motor oil can be used in a 2002 Chevy Cavalier?

The best motor oil for a 2002 Chevy Cavalier depends on the engine it has (it's likely a 2.2L Ecotec or a 2.4L Ecotec) and the climate where you live. However, a good starting point would be looking at the owner's manual for the specific recommendations.

Generally, for a 2002 Cavalier, you'd want to use a conventional or synthetic blend motor oil that meets at least SAE 5W-30 specifications. Some owners might opt for full synthetic 5W-30 as well, offering better protection and potentially longer drain intervals (always check your owner's manual for recommendations on this).

Before you buy oil:

* Check your owner's manual: This is the most important step! The manual will specify the recommended viscosity (like 5W-30) and API certification (like SM or SL - older standards are fine for this age of car, but newer ones are acceptable too).

* Consider your climate: In very cold climates, a 0W-30 might be a better choice for easier starting. In very hot climates, a 10W-30 might be suitable, but again, check your manual.

Using the wrong oil can damage your engine. Always consult your owner's manual for the best recommendations.
