2004 Jaguar XJ8

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2004 XJ8.

Transmission Automatic 6-spd

The 2004 Jaguar XJ8 sits in the latter half of a model run that stretched from 1998 to 2006, equipped with a six-speed automatic transmission and EPA-rated at 16 mpg in the city, 25 mpg on the highway, and 19 mpg combined. Within that nine-year window the XJ8's complaint history moved from a peak of 84 reports in 1998 down to just 4 by 2006, placing the 2004 model year on the descending side of the curve. For a researcher, that positioning means the 2004 XJ8 represents a maturing example of the model—well past its initial problem years but still a step removed from its quietest vintage.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 10,000 mi; spark plugs every 100,000 mi; coolant every 10,000 mi. The big-interval services (every 10,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.
