However, generally speaking, a 2002 Jeep Wrangler would likely use one of these:
* SAE 5W-30: This is a common and often recommended viscosity for many engines. Many modern synthetics and blends are available in 5W-30.
* SAE 10W-30: This is another possibility, especially if the vehicle is older and has higher mileage. Again, check your owner's manual for specifics.
Crucially, you also need to consider the oil type:
* Conventional: The least expensive but requires more frequent changes.
* Synthetic Blend: A balance of cost and performance.
* Full Synthetic: The most expensive but offers better protection and longer intervals between changes.
Don't guess! Checking your owner's manual is absolutely essential to ensure you're using the correct oil for your specific Jeep Wrangler's engine. Using the wrong oil can damage your engine.
