1991 Buick Park Avenue

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

Transmission Automatic 4-spd

The 1991 Buick Park Avenue pairs a 4-speed automatic transmission with a powertrain rated at 16 city, 24 highway, and 19 combined mpg, its engine requiring 4.0 quarts of 10W-30 API oil. Within the model's documented complaint history, which spans 1994 through 2005, complaints peaked at 301 in 1997 before declining to just 8 by 2005. Because the 1991 model year predates the earliest year in that tracked range, it occupies a comparatively quiet early position in the model's reliability timeline — meaning the foundational years carried fewer documented issues than the mid-cycle surge that followed.

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.
