Engine Oil Change Guidance

Oil Specifications and Capacities

The 2012 Continental Supersports's 6.0L twin-turbo W12 engine requires high-quality fully synthetic oil meeting Bentley's factory standards .

Oil Change Interval

• Factory recommendation: Every 12 months or 16,000 km (10,000 miles)
• Conservative owner guidance: Never exceed 12 months for an oil change, even if the mileage is low, as synthetic oil can degrade over time. For vehicles driven primarily in extreme climates or for short urban journeys, many specialists recommend more frequent changes.
