The cooling system for the 1997 BMW 528i requires a capacity of 11.1 quarts to ensure proper thermal management. Ethylene glycol-based coolants can break down over time, leading to corrosion or freezing in extreme conditions. Switching to AMSOIL Passenger Car & Light Truck Antifreeze & Coolant protects all cooling system metals, gaskets, and hoses while preventing rust and scale buildup. Both concentrated and pre-mixed options are available to suit your maintenance preferences, such as the AMSOIL Propylene Glycol Antifreeze and Engine Coolant.
- AMSOIL Passenger Car & Light Truck Antifreeze & Coolant – This unique poly-organic acid formulation provides protection up to 150,000 miles or 5 years. It is phosphate-, nitrate-, and silicate-free, making it compatible with all other coolant colors and safe for all metals.
- AMSOIL Propylene Glycol Antifreeze and Engine Coolant – A concentrated option that greatly surpasses standards for metallic corrosion and erosion, offering protection for up to 150,000 miles in passenger cars or significantly longer in heavy-duty applications.
Transmission and Drivetrain Lubrication
The 1997 BMW 528i typically comes with an automatic transmission (4L30-E), which requires a total fill of 9.3 quarts, or a manual transmission (S5D320Z) requiring 2.5 pints. Using the correct automatic transmission fluid is critical for smooth shifting and preventing wear. For the 4-speed automatic, AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid remains fluid in sub-zero temperatures while withstanding the rigors of heavy use and elevated operating temperatures.
- AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid – This fluid provides reserve protection during heavy use and abuse, guarding against sludge and ensuring shudder-free shifts even in challenging terrain.

For the rear limited-slip differential (188K), the capacity is 2.5 pints. Standard gear lubes can fail under the high shear stress of a limited-slip differential, leading to noisy operation and wear. AMSOIL SEVERE GEAR 75W-140 100% Synthetic Gear Lube contains friction modifiers specifically designed for limited-slip applications, helping to reduce operating temperatures and extend the life of the gear set.
- AMSOIL SEVERE GEAR® 75W-140 100% Synthetic Gear Lube – This advanced lubricant controls thermal runaway and protects against rust and corrosion, ensuring long oil life for the differential components.
Braking system integrity is paramount for any vehicle, especially a high-performance sedan like the BMW. The hydraulic system in the 528i requires AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid. This synthetic brake fluid provides excellent ABS and traction-control responsiveness by maintaining stable viscosity over a wide temperature range.
- AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid – Designed to absorb water and maintain performance, this fluid ensures reliable braking power and helps prevent boiling under heavy braking conditions.
Fuel System and Vehicle Care
To keep the 2.8-liter engine running efficiently, using a gasoline additive like AMSOIL P.i.® Performance Improver Gasoline Additive can restore lost horsepower and improve fuel economy.
