Oil Change Interval:
Typically every 6,000-10,000 miles or annually, with synthetic oil.
Major Service Intervals:
Spark plug replacement around 60,000-100,000 miles (refer to manual for exact type), coolant flush, transmission service recommended around 50,000-80,000 miles.
Engine Oil Type:
SAE 5W-30 or 5W-40 Synthetic, meeting Jaguar specifications (e.g., Jaguar Engine Oil Specification WSS-M2C200-CD).
Coolant Type:
Ethylene Glycol based coolant, Jaguar specification (e.g., Jaguar Coolant specification XCL-17000).
Brake Fluid Type:

Plastic Water Pump Impeller:
Early AJ-V8 engines are prone to plastic water pump impeller failure, leading to overheating. Recommended replacement with a metal impeller kit.
Timing Chain Tensioners:
While less problematic than later 4.0L Jaguar engines, early tensioners can still degrade. The manual would detail inspection and replacement procedures.
Nikasil Cylinder Liners:
Early 4.0L AJ-V8 engines used Nikasil cylinder liners, which could be susceptible to wear with high sulfur content fuel. This was rectified with steel liners in later production. The manual would provide diagnostic information.
Active Dampers:
Some models featured adaptive suspension (CATS - Computer Active Technology Suspension) which can develop issues with the dampers or control module. The manual will cover diagnostics.
