1989 Mitsubishi Mighty Max — 2.6L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1989 Mighty Max 2.6L.

Engine 2.6L

The 1989 Mitsubishi Mighty Max is a compact pickup built around a 2.6L engine, with an oil system that holds 4.8 quarts and accepts 20W-40, 10W-30, or 5W-30 API viscosities. This model year predates the complaint history tracked from 1990 to 1996, where the 1991 peak reached 11 complaints, and its own record of just two owner complaints and a single recall—focused on seat belts—positions it as a notably trouble-free entry in the Mighty Max lineage.

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 for the Mighty Max generation begins in 1990, the year immediately after the target 1989, showing 7 complaints and 1 recall for that model year. Complaints rose to a peak of 11 in 1991, then steadily fell to just 3 by 1996, while recalls were limited to the first two years of the record (one each in 1990 and 1991) and never reappeared. Over the same span, Technical Service Bulletins (TSBs) grew from 5 in 1990 to 19 in 1996, indicating that the manufacturer issued increasingly more service guidance as the fleet aged. For 1989 itself, the only logged complaint categories are Seat Belts and Structure, each with a single complaint, and the vehicle recorded zero crash‑related or fire complaints. This positions 1989 at the start of a period where defect‑related complaints were low and recall activity was absent, suggesting the model year entered its service life with relatively few documented issues. Consequently, a used 1989 Mitsubishi Mighty Max appears to be a comparatively low‑risk purchase within this generation, though buyers should still review any relevant TSBs that may apply to its age.
