1991 Toyota MR2 (Turbo)

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1991 MR2 (Turbo).

The 1991 Toyota MR2 Turbo represents the forced-induction variant of Toyota's MR2 platform, an engine package that calls for 4.1 quarts of oil — specified at either 10W-30 or 5W-30 API — to maintain proper lubrication. Within the MR2's reliability history, this model year occupies a relatively favorable position, with only 13 total owner complaints and a single recall on record. The top complaint area, Engine & Engine Cooling, points researchers toward the turbocharged powertrain as the primary focus of scrutiny — though the modest overall complaint volume indicates this model year stands as one of the cleaner entries in the lineup's track record.

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.

Owner complaints about the 1991 Toyota MR2 (Turbo) lead in one area — the engine & engine cooling, 3 of 13 reports (23%), well ahead of the next concern. None of this vehicle's 1 recall campaigns target the engine & engine cooling, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 1 of the reports describe a crash and 2 a fire — a small share of the total, but worth weighing against the engine & engine cooling pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
