1991 Mitsubishi 3000GT — 3.0L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1991 3000GT 3.0L. Covers both the standard and High Output 3.0L.

Engine 3.0LTransmission Automatic 4-spd

The 1991 Mitsubishi 3000GT 3.0L pairs its 3.0-liter engine with an automatic four-speed transmission, requires 4.2 quarts of oil across 20W-40 to 5W-30 API grades, and carries EPA fuel-economy ratings of 16/22/18 mpg city/highway/combined. With 63 owner complaints and five recalls on file, it sits at the beginning of the 1991–2002 model run, a period whose complaint count peaked at 117 in 1992 and fell to just one by 2001. That early placement gives the 1991 car a complaint total well below the 1992 peak yet far above the 2001 low, so researchers should treat its power train–weighted reliability profile as representative of an opening phase that generated substantially more owner reports than the closing years of the 1991–2002 span.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 7,500 mi; spark plugs every 60,000 mi; coolant every 30,000 mi. The big-interval services (every 30,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

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 1991 Mitsubishi 3000GT initiates the provided federal record with 63 complaints and the highest recall frequency of 5, exceeding every subsequent year listed in the dataset. While consumer complaints peaked in 1992 at 117 before trending downward to 12 by 1999, the 1991 model year distinguishes itself with a heavy concentration of Power Train complaints, representing 38 of the total reports. Technical Service Bulletins show an inverse trend, rising from 11 in 1991 to a peak of 40 in 1997, indicating increased documented service guidance for later models despite lower complaint volumes. This launch year also carries 3 investigations, which is higher than the single investigation recorded for most years from 1994 through 1999. Buyers seeking to minimize recall and investigation exposure should prioritize later model years over this 1991 example.
