Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1998 XJ8 L.
The 1998 Jaguar XJ8 L is a long-wheelbase luxury sedan powered by a V8 engine paired with a five-speed automatic transmission, representing the flagship variant of Jaguar's XJ series for that model year; it achieved EPA fuel economy ratings of 15 mpg in the city, 22 mpg on the highway, and 18 mpg combined. This particular model year stands out in the XJ8's reliability record with zero recalls issued and a relatively modest total of 15 owner complaints filed, with engine and engine cooling issues comprising the most frequently reported concern. For researchers examining the XJ8's historical dependability, the 1998 model year offers a notably cleaner recall history compared to later iterations of the platform, suggesting fewer systematic manufacturing defects despite the model's reputation for periodic electrical and mechanical quirks typical of Jaguar's postwar vehicles.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Owner complaints about the 1998 Jaguar XJ8 L dominate in one area — the engine & engine cooling, 6 of 15 reports (40%), well ahead of the next concern. NHTSA has issued no recalls for this vehicle, so these are owner-reported concerns only. 1 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the engine & engine cooling pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
