To find the exact oil capacity for your 1996 Mercedes E320, I recommend checking:
* Your owner's manual: This will be the most accurate source of information.
* A reliable online resource: Websites like Mercedes-Benz's official website, AutoZone, or Advance Auto Parts often have information on specific car models.
* A qualified mechanic: A mechanic can easily check the oil capacity for your specific vehicle.
Please note that the oil capacity can vary slightly depending on the engine type and other factors.
