Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1983 Montero 2.6L.
The 1983 Mitsubishi Montero is powered by a 2.6L engine that requires 4.6 qt of oil and can be run with 20W‑20, 20W‑40, or 20W‑50 viscosity. Complaint records for the Montero line spanning 1990‑2006 show a high of 174 reports in 2002 and a low of just one report in 2005, reflecting a sharp decline in issues during the latter part of that period. Positioned before this complaint window, the 1983 model serves as the early‑generation benchmark against which the later trend of improving reliability can be measured.
