1991 Toyota Supra (Turbo)

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

Transmission Automatic 4-spd

The 1991 Toyota Supra Turbo pairs its turbocharged drivetrain with a four-speed automatic transmission and a 4.7-quart oil capacity filled with 10W-30 or 5W-30 API-grade lubricant, returning 16 city, 21 highway, and 18 combined mpg under EPA testing. Owner-reported data for the year is sparse, with only six complaints filed across the model and engine and engine cooling accounting as the top concern, alongside a record of zero recalls issued. That lean complaint profile and clean recall standing position the 1991 Supra Turbo as a comparatively dependable reference point within the model's broader reliability history, useful as a baseline rather than a cautionary data point.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 5,000 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 Supra (Turbo) dominate in one area — the engine & engine cooling, 2 of 6 reports (33%), well ahead of the next concern. NHTSA has issued no recalls for this vehicle, so these are owner-reported concerns only. 0 of the reports describe a crash and 0 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.
