Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1998 C-Series MD Truck C6/C7/C8.
The 1998 Chevrolet C-Series MD Truck range—covering the C6, C7, and C8 medium-duty variants—stands as a gasoline-powered commercial entry whose archival footprint is exceptionally light. The model year registered only one owner complaint spanning Engine & Engine Cooling and Fuel System, Gasoline issues, and it carried zero recalls. That scarcity of documented problems positions the 1998 C-Series at the quiet extreme of the line’s reliability record, meaning researchers face a sparse dataset when mapping systemic or recurring mechanical concerns.
