1991 Oldsmobile Toronado

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1991 Toronado.

Transmission Automatic 4-spd

The 1991 Oldsmobile Toronado pairs a four-speed automatic transmission with EPA fuel-economy ratings of 16 mpg city, 24 mpg highway, and 19 mpg combined. In the reliability record, this model year has attracted just four owner complaints, with the electrical system the most-reported area and a single recall attached — a markedly quieter figure than the 16 complaints logged for 1990. Set against the 1990-1995 complaint history tracked for the Toronado, 1991 sits between that early high and the 1995 low of a single complaint, framing it as a comparatively settled point in the nameplate's quality arc and a relatively low-risk year for a researcher or used-buyer to weigh.

From the factory this vehicle uses OE oil filter 12731175. Note the factory serpentine belt is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known. Each part links to every other vehicle that shares it, so a part you already stock may fit more of your fleet than you'd expect.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter at 7,500 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.

In 1991 the Toronado logged only four consumer complaints, a sharp drop from the 16 recorded in 1990, and just one recall, the fewest recall events across the years shown. However, the 1991 model generated four Technical Service Bulletins (TSBs) – the highest TSB count in the dataset – focusing mainly on electrical system issues (two entries) and a mixed electrical‑engine‑fuel complaint plus a service‑brake hydraulic note. Compared with the modest rebound in complaints and recalls in 1992 (five complaints, two recalls, seven TSBs) and the near‑zero activity in 1995, 1991 sits at the low‑complaint, low‑recall trough but with an elevated TSB load, suggesting that while major safety problems were rare, owners faced a number of service‑related fixes. The data indicate that the 1991 Toronado had relatively few serious consumer grievances but may require attention to its electrical and brake systems; if you are prepared for potential TSB‑driven repairs, it remains a reasonably safe year to consider.
