2006 Jaguar XK8

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2006 XK8.

Transmission Automatic 6-spd

The 2006 Jaguar XK8 pairs a 6-speed automatic transmission with an EPA-estimated 19 mpg in combined driving, delivering a balance of grand-touring composure and efficiency. This model year recorded just four owner complaints, all concentrated in the power train, and no recalls. That figure stands well below the model’s previous low of 10 complaints in 2001, positioning the 2006 XK8 as a notably refined and dependable entry in the nameplate’s history.

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 Note the factory cabin air filter is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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 at 150,000 mi. The big-interval services (at 150,000 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 federal record data provided does not include 2006 in the year-by-year array, which ends at 2005, limiting direct comparison. However, the trend from 1997–2001 shows a steady decline in complaints (31 → 10) and TSBs (192 → 15), suggesting reliability improvements. The 2005 data point breaks this trajectory with complaints rebounding to 30 and TSBs rising to 92, indicating a reversal of the earlier gains. For 2006 itself, complaint areas are broadly distributed across Power Train, Fuel System, Suspension, and Electrical System at one complaint each, with zero crash-related complaints but one fire-related complaint on record. The data does not specify the root cause of the fire complaint. Given the 2005 spike in TSBs and the fire complaint in 2006, this generation of XK8 shows a possible reliability regression toward the end of its run, making a thorough pre-purchase inspection essential before buying a 2006 model.
