What is the correct antifreeze for 1998 xj8?

For a 1998 Jaguar XJ8, the recommended antifreeze is a mixture of ethylene glycol-based coolant with a 50/50 ratio of coolant to distilled water.

Always check the owner's manual for specific recommendations and avoid using conventional green antifreeze to prevent potential damage to the cooling system.
