The recommended Jaguar service schedule varies depending on the model vehicle you drive. It also varies with the type of engine, diesel, or gasoline, and size of the engine. For example, if your vehicle were the XF, and the new XJ 3.0 liter diesel, then your service would be: at 6,000 miles or 12 months, 32,000 miles or 24 months, 48,000 miles or 36 months, 64,000 miles or 48 months, 80,000 miles or 60 months, and 96,000 miles or 72 months–so, check your manual. This schedule must be adhered to, and time starts from the date of purchase by the first owner.
