1993 Cadillac Allante

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1993 Allante.

Transmission Automatic 4-spd

The 1993 Cadillac Allante paired a 4-speed automatic transmission with EPA ratings of 13 mpg city, 20 mpg highway, and 15 mpg combined, and called for 7 quarts of 5W-30 API oil at service. Across the model year, owners filed just nine complaints — with the electrical system as the most-cited area and a single recall on record. Within the Allante's 1990–1995 production run, that number looks unusually lean, a far cry from the 41 complaints logged in 1990 and a hint that this mid-run model year delivered a markedly calmer ownership experience than the nameplate's earliest buyers saw.

From the factory this vehicle uses OE oil filter 12731179. Note the factory front wiper blades is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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; spark plugs every 100,000 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.

The 1993 Cadillac Allante sits at the end of a clear downward trend in owner complaints, dropping from 41 in 1990 to just 9, and further to 1 in 1995, suggesting improving field reliability as the generation matured. Recalls remained constant at one per year through 1993, while investigations fell from a peak of 5 in 1992 to only 1 for the target year. Notably, 1993 saw a sharp spike to 12 technical service bulletins—far above the 2–3 of prior years—indicating that while major issues were fewer, the manufacturer was actively documenting a range of fixes. The top complaint area was the electrical system, with 3 reports, and the year recorded 2 fire-related complaints and 1 crash complaint, though the data does not specify root causes. Overall, the 1993 Allante appears to be a relatively reliable choice within the generation, but a buyer should ensure the numerous service bulletins have been addressed.
