2001 Jaguar XK8

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2001 XK8.

Transmission Automatic 5-spd

The 2001 Jaguar XK8 carries forward the model's grand touring formula with a five-speed automatic transmission and EPA fuel economy ratings of 15 mpg city, 22 mpg highway, and 18 mpg combined. Within the broader XK8 lineage covered from 1997 through 2005, this particular model year stands as the least-complained-about example on record, drawing just 10 owner complaints — a sharp contrast to the 1998 peak of 32 — with vehicle speed control emerging as the most-cited concern alongside a single recall. That statistical floor makes the 2001 an unusually clean reference point for researchers tracing the model's reliability arc, even as the speed control category remains the most prominent thread in its complaint profile.

Fitment & sizes

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

From the factory this vehicle uses a BCI 49 · 680 CCA battery, OE oil filter EAZ1354. Note the factory cabin air filter is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 2001 Jaguar XK8 sits at the low point of a clear downward trend in complaints and technical service bulletins (TSBs) across the generation, with just 10 complaints and 15 TSBs—down from 31 complaints and 192 TSBs in 1997. Recalls also declined from two in the earliest years to a single recall for 2001, matching the 1999 and 2000 model years. This steady improvement is sharply reversed in the 2005 model year, where complaints jump to 30 and TSBs to 92, though no investigations were recorded for any year. The 2001 model’s top complaint areas are limited to two each for vehicle speed control and steering, with only two crash complaints and no fire complaints, indicating no widespread systemic issues. Given this data, the 2001 Jaguar XK8 represents the most refined and least problematic year in the provided record, making it a strong candidate for purchase.
