1991 Cadillac Allante

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

Transmission Automatic 4-spd

The 1991 Cadillac Allante is specified with an automatic 4-speed transmission, EPA ratings of 14/20/16 mpg, and a 6-quart 5W-30 API oil capacity, establishing the mechanical baseline for this model year. Reliability data record 33 owner complaints and one recall, with service brakes and hydraulic systems registering as the top complaint area. That complaint count sits near the high end of the 1990-1995 range, trailing only the 1990 peak of 41 reports, meaning researchers should treat brake-system maintenance records as an important focus when evaluating this model year.

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 Note the factory fuel filter, front wiper blades and serpentine belt are now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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

Federal records show a consistent decline in complaints from the 1990 model year's 41 incidents to 33 for the 1991 Cadillac Allante, continuing downward to 23 in 1992. The 1991 model maintains the same single recall and three investigations as the preceding year, though Technical Service Bulletins increased from two to three. Hydraulic service brakes represent the primary complaint area for this year, comprising 23 of the 33 total reports, alongside two recorded crash complaints. While complaints decrease in subsequent years, the 1991 model sits in the early generation arc where complaint volume remains notably higher than the single-digit figures seen in 1993 and 1995. Given the concentrated brake-related complaints and higher complaint volume relative to later production years, buyers should prefer later model years or ensure the braking system is verified before purchase.
