Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1987 M6.
The 1987 BMW M6 is a distinct model characterized by specific engine lubrication requirements, most notably a 5.3-quart oil capacity and a recommended viscosity of 20W-50, 15W-50, or 10W-50 API SL. When contextualized within the model's recorded complaint history from 2006 through 2019, the data shows a peak of seven complaints in 2006 that steadily declines to a single reported issue by 2017. This downward trajectory suggests that the platform's long-term reliability has stabilized over time, meaning surviving examples offer a more predictable ownership experience for researchers today.
