1991 Chevrolet Caprice

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

Body PASSENGER CAR

The 1991 Chevrolet Caprice is a passenger car requiring 4.0 quarts of 10W30 API engine oil, and it carries a reliability record marked by 169 owner complaints and 10 recalls, with Service Brakes, Hydraulic representing the most frequently cited concern. Within the model’s 1990–2011 complaint history, the 1991 model year falls below the 1994 peak of 196 complaints yet sits far above the 2003 low of a single reported issue, positioning it as a higher-volume complaint year relative to the line’s later iterations. This concentration of early-decade feedback indicates the 1991 model reflects a more problematic phase of the Caprice’s production run before reported issues declined in subsequent years.

From the factory this vehicle uses OE oil filter 12708762. Note the factory engine air filter and front wiper blades are now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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 Chevrolet Caprice represents a dramatic spike in federal records compared to the preceding 1990 model year, which saw only 6 complaints, 2 recalls, 2 investigations, and 1 TSB, jumping to 169 complaints, 10 recalls, 6 investigations, and 7 TSBs. Across the generation, complaint volumes fluctuate wildly—dropping in 1993 before peaking again in 1994—while recalls remain elevated until 1997, suggesting persistent regulatory scrutiny throughout the early-to-mid 1990s. Sitting at the beginning of this troubled arc, the 1991 model suffers from significant vulnerabilities, with the data highlighting the Service Brakes, Hydraulic (37 complaints), Electrical System (17), and Vehicle Speed Control (16) as primary problem areas that contributed to 25 crash and 3 fire complaints. Although the data does not specify the root causes of these failures, the high number of recalls and investigations implies systemic flaws that were actively targeted for correction in subsequent years. Given the disproportionate safety concerns and first-year production risks compared to the calmer 1993 model year (70 complaints and 2 investigations), the 1991 Caprice is a risky purchase and should generally be avoided by used buyers.
