The 2016 BMW 328i is a sophisticated sports sedan powered by a turbocharged 2.0L four-cylinder engine (Engine Code N20B20A). To maintain its precise handling, smooth power delivery, and long-term reliability, using lubricants designed specifically for European performance vehicles is essential. Standard mineral oils often fail to protect the tight tolerances and high temperatures found in this engine, particularly when subjected to extreme weather or spirited driving.
Recommended AMSOIL Products
- AMSOIL 0W-20 LS 100% Synthetic European Motor Oil – Specifically formulated for the unique demands of gasoline and diesel European vehicles, this oil offers a precise blend of synthetic base oils and premium additives to protect the N20 turbocharger and engine internals.
- AMSOIL Oil Filter – This filter provides 99% efficiency at 20 microns and offers greater capacity for small contaminants than competing filters, ensuring maximum oil flow and reduced engine wear.
- MANN-FILTERS Oil Filter – Featuring premium media, this option offers distinct improvements over original equipment manufacturer-branded filters and serves as a direct fit alternative.
Proper lubrication is critical for the longevity of the 2016 BMW 328i. The N20B20A engine operates under high thermal stress, especially due to the turbocharger and its direct injection system. Using the recommended 0W-20 viscosity ensures immediate lubrication upon startup in cold temperatures while maintaining a strong oil film at operating heat. The AMSOIL Oil Filter and the alternative MANN-FILTERS Oil Filter work in tandem with the oil to trap particles that can cause wear on camshafts, pistons, and bearings. Without the correct filtration and oil quality, sludge buildup can restrict oil passages, leading to catastrophic engine failure over time.
Engine Oil Specifications and Oil Change Kits
For the 2016 BMW 328i with the 2.0L 4-cylinder engine, the required oil grade is 0W-20 for all temperatures. The system capacity is 5.3 quarts when performing an oil change including a filter replacement. After refilling, it is vital to check the oil level to ensure it is within the correct range.
The oil drain plug torque specification is 6 ft/lbs. When reinstalling the plug, ensure the latch mechanism is properly aligned. If the new drain plug does not latch after tightening to the specified torque, the plug must be repositioned until the mechanism engages correctly. A complete oil change kit is available, combining the AMSOIL 0W-20 LS 100% Synthetic European Motor Oil with the AMSOIL Oil Filter to take the guesswork out of the service process.
Transmission Fluid and Clutch Care
Automatic transmission health is a priority for this vehicle, as the 8-speed automatic transmission (GA8HP45Z) experiences significant stress. The total fill capacity for a complete flush is approximately 9 quarts. AMSOIL recommends two distinct options for this application depending on the owner’s needs. The AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is designed to withstand heavy towing, elevated temperatures, and challenging terrain while remaining fluid in sub-zero conditions. Alternatively, the AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid provides OE-equivalent protection that guards against wear and temperature-related problems, offering extended service intervals.
The 328i is equipped with a manual clutch that requires specific fluid maintenance. The recommended fluid is BMW P/N 81 22 0 142 156 or 81 22 0 142 155. If these specific BMW parts are unavailable, a low viscosity DOT 4 brake fluid is an acceptable substitute. For optimal performance and safety, the AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid provides excellent ABS and traction-control responsiveness with a stable viscosity across a wide temperature range.
Coolant and Cooling System Maintenance
Maintaining the cooling system is vital for a turbocharged engine, which generates significant heat. For automatic transmission-equipped models, the cooling capacity is 8 quarts, while manual transmission models require 7.4 quarts. AMSOIL offers two effective antifreeze options. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a unique poly-organic acid (OAT) formulation that is a 50/50 pre-mix, providing protection for up to 150,000 miles or 5 years. It is phosphate, nitrate, nitrite, silicate, borate, and amine-free, making it safe for all cooling system metals. For those preferring a concentrate, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers even longer service intervals, with protection up to 150,000 miles or 5 years, and greatly surpasses standards for metallic corrosion.
Additional Fluids and Performance Additives
Keeping the fuel system clean is crucial for the 328i’s direct injection system. The AMSOIL P.i.® Performance Improver Gasoline Additive is designed to restore fuel injectors to 100% flow rate after a single tank of fuel. This additive can restore up to 14% horsepower, improve fuel economy, and help prevent carbon buildup and pre-ignition knock. It is compatible with capless fuel systems and helps reduce the need for higher-octane fuel.
For seasonal storage or long-term inactivity, the AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, protecting against varnish, gum, and ethanol corrosion. Additionally, the AMSOIL Engine Fogging Oil is highly effective for preventing rust on internal engine components during storage. For general cleaning, the AMSOIL Brake and Parts Cleaner quickly removes oil, grease, and brake fluid, leaving no residue that could cause squeal or chatter.
Additional Care and Protection Products
Beyond the essential fluids, there are several products available to protect the mechanical and cosmetic aspects of the vehicle. The AMSOIL Upper Cylinder Lubricant Corrosion Inhibitor lubricates the fuel system and upper cylinders. For exterior protection, the AMSOIL Exterior Ceramic Spray requires no cure time and sheds water rapidly while protecting against UV rays. For a quick wash and wax, the AMSOIL Miracle Wash Waterless Wash and Wax Spray is an excellent choice.
For metal protection against rust, corrosion, and salt, the AMSOIL Heavy-Duty Metal Protector leaves a long-lasting, protective, wax-like coating. The AMSOIL Silicone Spray provides a dry lubricating film ideal for surfaces that may be damaged by conventional lubricants, protecting rubber and locking out moisture. For general purpose lubrication, the AMSOIL Synthetic Multi-Purpose Grease resists thermal and oxidation degradation, ensuring long-term performance even under heavy loads. The AMSOIL Power Foam® Carburetor and Induction-System Cleaner can be used to clean deposits from fuel systems, restoring startability and horsepower.
Vehicle Background
The 2016 BMW 328i represents a pivotal moment in the history of the BMW 3 Series. It belongs to the F30 generation, a model line that was widely praised for its engineering excellence and balance between sportiness and daily practicality. At the heart of this vehicle is the N20 engine, a 2.0-liter turbocharged inline-four cylinder. This engine replaced the older naturally aspirated four-cylinders, bringing modern efficiency and torque to the compact sedan segment.
Owners of the 2016 328i often cite the car’s nimble handling and refined ride quality as standout features. The suspension is tuned to offer a compliant experience on daily commutes while remaining firm enough to provide engaging dynamics on winding roads. The interior design of this era focuses on a driver-centric cockpit, with high-quality materials and intuitive controls. The 328i is not a track-focused machine like the M3, but it is considered one of the most balanced sedans in the luxury compact class, offering a perfect blend of acceleration, handling, and comfort. Its reputation for durability is high, provided that it receives regular maintenance with the correct synthetic fluids. The turbocharged nature of the engine means that it relies heavily on high-quality oil to protect the turbocharger bearings and the direct injection system from carbon buildup. Keeping up with fluid changes and using premium lubricants ensures that this sophisticated machine continues to perform as intended for years to come.
