The 2001 Jeep Wrangler with the 2.5L 4Cylinder engine requires 4 quarts of SAE 10W-30 oil, while the 4.0L 6 cylinder engine needs 6 quarts of the same oil. Jeep suggests using synthetic oil for better protection when it's time for an oil change. There are two main types of oil: conventional, made from petroleum, and synthetic, developed in a lab for improved lubrication. Synthetic oil lasts longer than conventional, allowing you to extend your oil change intervals to around 7,500 miles, compared to the 3,500 to 5,000 miles with standard oil. It's important to check your Wrangler's oil monthly to ensure it's at the right level and free of damage signs.
The 2001 Jeep Wrangler can be equipped with either a 2.5L inline-4 engine or a 4.0L inline-6 engine. The smaller engine needs 4 quarts of 10W30 oil in warmer weather or 5W30 in colder temperatures. The larger engine requires 6 quarts of the same types of oil based on the temperature conditions.
