The '528i' designation for 1981-1988 typically refers to the European spec 2.8L or a North American 3.2L variant. For North America, the 3.2L '528i' (M30B32 engine) was primarily for 1979-1981. By 1981, the 528i (E28) in the US was replaced by the 533i. However, the manual *specifically* states 528i for 1981-1988. This suggests it might cover the specific 528i model if it was offered in certain markets or might be a broader manual for the E28 chassis that includes the 528i engine variants where applicable. Given the M30 engine family, it's highly probable this manual covers variants of the 3.2L M30 engine used in North American 528i (E12) and potentially early E28 models or export market 528i. Engine Type: Inline 6-cylinder, SOHC Displacement: 3.2 Liters (approximately 3210 cc for M30B32) Performance Horsepower: Approximately 181 hp @ 5500 rpm (for M30B32 US spec) Torque: Approximately 195 lb-ft @ 3500 rpm (for M30B32 US spec) Fuel System Fuel Delivery: Bosch L-Jetronic or Motronic fuel injection (depending on exact model year and market) Fluid Specifications Engine Oil Type: Refer to manual for specific viscosity (e.g., 10W-40 or 20W-50 common for the era, API SG or higher recommended). Engine Oil Capacity: Refer to manual (typically around 6.5 US quarts / 6.2 liters with filter for M30 engine). Maintenance Items Spark Plugs: Refer to manual for specific part number...
