1991 Cadillac Seville

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

The 1991 Cadillac Seville, equipped with a 5.0-quart oil capacity requiring 5W-30 viscosity and a 4-speed automatic transmission, returned EPA fuel economy ratings of 15 city, 24 highway, and 18 combined. Among the model years spanning 1990 to 2004, the 1991 Seville recorded only 25 total owner complaints—far fewer than the 1996 peak of 131 and comparable to the 2004 low of 17—with its most common issue being the service brakes hydraulic system, and it carried zero recalls.

From the factory this vehicle uses OE oil filter 12731179. Note the factory serpentine belt is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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.

The 1991 model sits at the very start of this generation’s federal record, posting 25 complaints—just two above the 1990 model’s 23—while recording zero recalls compared to three the year prior and one in 1992. Across the generation, complaints climb steeply to a 131-complaint peak in 1996 before trending downward, while TSBs remain minimal through the early 1990s before ballooning to several hundred annually by the 2000s. With zero recalls, zero investigations, and only four TSBs, 1991 carries the lightest federal enforcement footprint of nearly the entire run, suggesting it predates the escalating defect patterns documented in later years. Reported complaints for 1991 concentrated in Service Brakes, Hydraulic and Air Bags, though the data does not specify root causes. Given its position before the generation’s broad mid-1990s surge in complaints, recalls, and investigations, the 1991 Seville represents one of the more favorable years to buy from a federal-record standpoint.
