2004 Jaguar XK8

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2004 XK8.

Transmission Automatic 6-spd

Defining its mechanical character, the 2004 Jaguar XK8 routes power through a 6-speed automatic transmission and returns an EPA-rated 16 city and 24 highway mpg for a 19 mpg combined average. Within the context of the model's 1997-2005 complaint history, this year lands well past the generation's problematic 1998 peak of 32 complaints and the subsequent 2001 low of 10 complaints. Occupying this late stage of the lifecycle means the 2004 XK8 represents a matured iteration, where the early-production issues that drove that initial peak had largely been resolved by this point in the model's run.

Fitment & sizes

Replacement part sizes and factory part numbers — battery, bulbs, filters and belts.

From the factory this vehicle uses a BCI 49 · 750 CCA battery, OE oil filter C2C41611. Note the factory cabin air filter is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known. Each part links to every other vehicle that shares it, so a part you already stock may fit more of your fleet than you'd expect.

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.
