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 features a 2.6‑liter engine mated to a three‑speed automatic transmission, holds 4.6 qt of oil that can be run in 20W‑20, 20W‑40 or 20W‑50 viscosity, and carries an EPA rating of 16 mpg for city, highway and combined driving. Although the Montero’s complaint history is documented from 1990 to 2006 — reaching a high of 174 reports in 2002 and a low of just one report in 2005 — the 1984 model year precedes that tracking period, so its reliability cannot be directly gauged by those figures. This places the 1984 Montero before the era of recorded variability, meaning any assessment of its dependability must rely on sources outside the supplied complaint data.
