Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1984 Riviera.
The 1984 Buick Riviera is a personal luxury coupe whose 4-quart engine oil capacity—specified across 20W-20, 10W-30, or 10W-40 viscosity grades—reflects the era's straightforward lubrication requirements for a car of this class. The available complaint history for the Riviera line spans 1990 through 1999, which does not encompass this 1984 model year, meaning the documented reliability record begins with later generations. Within that recorded window, complaints peaked at 148 in 1995 before declining to just 6 by 1999, suggesting the most troubled years fall well downstream of this particular model and leaving the 1984 Riviera's own reliability picture outside the available data.
