Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1984 Montero 2.6L.
The 1984 Mitsubishi Montero 2.6L is a compact SUV powered by a 2.6-liter four-cylinder engine paired with a 3-speed automatic transmission, achieving EPA-rated fuel economy of 16 mpg across city, highway, and combined driving cycles. The engine holds 4.6 quarts of oil with a viscosity tolerance spanning 20W-20 through 20W-50, reflecting the broader tolerances acceptable for this powerplant. Though the 1984 model year predates the 1990–2006 complaint tracking window—during which complaint volumes ranged dramatically from a peak of 174 in 2002 down to just 1 in 2005—this early-generation Montero represents the vehicle's foundational platform before later refinements that would see both significantly higher and notably lower complaint frequencies over the model's lifespan.
