Oil Change Interval:
Typically every 5,000-7,500 miles (8,000-12,000 km) or 12 months, depending on driving conditions and oil specification.
Transmission Fluid Interval:
Recommended service around 60,000 miles (96,000 km) or as per the manual's specific guidance.
Engine Oil Type:
API SJ or SL rated, SAE 5W-30 or 5W-40 synthetic oil recommended (refer to manual for precise specification).
Coolant Type:
Ethylene glycol based coolant, typically a 50/50 mix with distilled water. Jaguar specific coolant recommended.
Transmission Fluid Type:
Mercon V or equivalent ATF (refer to manual for exact specification and capacity).
Timing Chain Tensioners:
