To find the correct engine oil capacity for your Peugeot Boxer 2.0 liter Diesel, I recommend:
1. Consult your owner's manual: This is the most reliable source for specific information about your vehicle.
2. Check the oil filler cap: Often, the oil capacity is printed directly on the oil filler cap.
3. Contact a Peugeot dealership or authorized service center: They can provide you with accurate information based on your vehicle's VIN.
Remember that using the wrong amount of oil can harm your engine. Always refer to the manufacturer's recommendations for proper maintenance.
