Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1983 Bonneville.
The 1983 Pontiac Bonneville is a full‑size sedan that requires a 4‑quart oil capacity and accepts the common 20W‑20, 20W‑40, or 20W‑50 viscosity grades. Its engineering lineage can be gauged by the model’s later reliability record, which between 1990 and 2005 recorded a peak of 299 consumer complaints in 1998 and a low of just 27 complaints by 2005. Consequently, the 1983 year sits toward the beginning of a period in which overall complaint volumes steadily declined, indicating a gradual improvement in durability across the model’s history.
