The 1994 Chevrolet P-Series MD Bus Chassis served as a mid-duty platform designed to underpin a variety of commercial and shuttle bodies, powered by a robust yet straightforward engine paired with a four-speed automatic transmission. With a modest oil capacity of just four quarts of 5W-30 API-rated lubricant, its powertrain reflected the era’s balance of durability and efficiency for vocational applications.
