1998 Land Rover Discovery

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1998 Discovery.

Transmission Automatic 4-spd

The 1998 Land Rover Discovery, built on the classic body‑on‑frame architecture with its 4‑speed automatic transmission, accepts 5.6 qt of engine oil and can be serviced with 20W‑40, 20W‑50 or 15W‑40 viscosity grades, while its EPA ratings of 12 mpg city, 16 mpg highway and 14 mpg combined reflect the era’s modest efficiency. Owner‑reported issues total 34 complaints for the model year, most frequently concerning seat belts, and the vehicle was subject to two recalls, placing it in the middle of the Discovery’s broader reliability trend that spans 1994‑2026. Within that span, the 1995 model saw the highest complaint count at 56, whereas the 2026 model registers a single complaint, indicating that the 1998 year occupies a relatively average reliability position in the line’s history.

Fitment & sizes

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

From the factory this vehicle uses a BCI 34 · 600 CCA battery, OE oil filter ERR3340. Note the factory serpentine belt is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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.

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 1998 Land Rover Discovery sits near the end of the first-generation run, where complaint volumes had receded from a peak of 56 in 1995 to 34, and recalls held steady at 2—matching the 1994 and 1997 levels. Across the generation, complaints spiked sharply in 1995 then declined, while TSBs dropped notably from 31 in 1997 to just 8 in 1998, suggesting that many early issues were addressed by the final model year. However, the 1998 model still logged 34 complaints, with seat belts and air bags as the top areas, plus 7 crash-related and 4 fire-related complaints, though the data does not specify root causes. Compared to the immediate successor 1999 model (21 complaints, 3 recalls), the 1998 year shows slightly higher complaint volume but fewer recalls. This year represents a mature version of the first-generation Discovery with a lower TSB count, yet the presence of safety-system complaints and fire incidents warrants caution; it may be a reasonable buy if a thorough pre-purchase inspection confirms no unresolved issues in those specific areas.
