What type of oil for the 99 Chevy Malibu?

The recommended oil type for a 1999 Chevy Malibu depends on the engine it has. There were several engines offered that year. To know for sure, you need to check your owner's manual. It will specify the correct oil viscosity (like 5W-30 or 10W-30) and the type (conventional, synthetic blend, or full synthetic).

Failing that, you can:

* Look for a sticker under the hood: Many cars have a sticker detailing recommended fluids.

* Check the oil fill cap: Sometimes the recommended oil type is printed on the cap.

* Use an online parts lookup: Websites like AutoZone, Advance Auto Parts, or Napa Auto Parts allow you to enter your vehicle's year, make, and model to find the correct oil. You'll need to know the engine size (e.g., 2.4L, 3.1L, 3.8L) which might also be on the sticker under the hood or the engine itself.

Do not rely on generic advice online without knowing your specific engine. Using the wrong oil can damage your engine.
