What 2003 Jeep Wrangler oil?

The recommended oil for a 2003 Jeep Wrangler depends on the engine. You must check your owner's manual for the specific recommendation. However, generally speaking, for a 2003 Jeep Wrangler with a:

* 4.0L inline-6 engine: The recommendation was typically SAE 5W-30. However, using a 10W-30 in warmer climates was also sometimes acceptable.

* 2.4L 4-cylinder engine: This likely also called for SAE 5W-30. Again, consult your owner's manual.

Crucially: The owner's manual will specify the *type* of oil (conventional, synthetic blend, or full synthetic) as well as the viscosity (like 5W-30). Using the incorrect oil can damage your engine. Always refer to your owner's manual before changing your oil.
