To find the exact engine oil capacity for your 2000 Nissan Xterra, I recommend checking the following:
* Your owner's manual: This is the most reliable source for information about your vehicle.
* The dipstick: The dipstick will give you a visual indication of the oil level.
* A trusted mechanic: They can provide you with the correct information.
Please note: The engine oil capacity can vary depending on the specific engine in your 2000 Xterra.
