Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1983 Montero 2.6L.
The 1983 Mitsubishi Montero 2.6L arrives as the inaugural generation built around a 2.6L engine that takes 4.6 quarts of oil across a viscosity range of 20W-20, 20W-40, or 20W-50. While the model's documented complaint history spans 1990 through 2006 — peaking at 174 reports in 2002 and bottoming out at just one in 2005 — the 1983 launch year falls outside that tracking window, leaving its early reliability profile to be inferred from later trends rather than direct data.
