Maintaining the 2016 Mitsubishi Lancer equipped with the 2.4L inline-four engine (Engine Code 4B12 W) requires precise fluid selection to ensure long-term reliability and optimal performance. This vehicle, originally designed for spirited yet efficient driving, benefits significantly from high-quality synthetic lubricants that can withstand the demands of modern driving conditions. Whether you are navigating city traffic, taking weekend highway cruises, or driving through varying seasonal temperatures, using the correct fluids minimizes wear, reduces sludge formation, and helps maintain fuel economy. Proper maintenance intervals are just as critical as the fluid choice itself, and adhering to manufacturer specifications while leveraging synthetic technology can extend the service life of the engine and transmission components.

Understanding the specific fluid requirements for the Mitsubishi Lancer 2.4L is essential for preventing premature component failure. The engine oil capacity for this vehicle is 4.9 quarts when the filter is replaced, making the choice of viscosity critical. AMSOIL’s 0W-20 synthetic oils are specifically engineered to meet the stringent requirements of this engine code, ensuring instant lubrication at startup and stable viscosity under heavy load. By using these synthetic options, you are not only meeting the API SN specifications but exceeding them with advanced chemistry that reduces friction and heat. This is particularly important for the 2.4L engine, which relies on precise tolerances to maintain power output and efficiency.
Beyond the engine, the transmission system demands attention. The 2016 Lancer with the 4B12 W engine typically utilizes a Continuously Variable Transmission (CVT) or an automatic transmission depending on the specific trim and configuration. For the CVT models, the factory requires a specific fluid to ensure the metal-to-metal friction characteristics remain within safe operating parameters. AMSOIL 100% Synthetic CVT Fluid is designed to handle the high heat and stress generated by this type of transmission, providing superior protection against slippage and wear. The total fill capacity for the transmission is listed as 7.3 quarts. Using a standard mineral oil in a CVT system can lead to poor shifting and eventual failure, whereas a synthetic alternative offers a buffer against the extreme thermal loads these transmissions experience.
The cooling system also plays a pivotal role in the longevity of the Lancer. The radiator capacity holds 7.4 quarts of fluid. AMSOIL offers two distinct options for this vehicle: a pre-mixed 50/50 ethylene glycol formulation and a concentrated propylene glycol option. Both are designed to be phosphate-, nitrate-, and silicate-free, which prevents the formation of deposits that can clog cooling passages. These formulations are compatible with all other antifreeze colors and protect against corrosion, freezing, and boiling over. Maintaining the correct AMSOIL Passenger Car & Light Truck Antifreeze & Coolant level and condition ensures the engine operates within its optimal temperature range, preventing issues like overheating in summer or freezing in winter.
Hydraulic systems such as the brake and power steering circuits also require specialized fluids to function correctly. The 2016 Lancer utilizes a DOT 3 hydraulic AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid system. AMSOIL’s DOT 3 and DOT 4 synthetic brake fluid maintains a stable viscosity across extreme temperature ranges, ensuring consistent pedal feel and responsiveness. For the power steering system, the fluid must protect seals and hoses from degradation while providing lubrication for the pump. The AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid is formulated to keep seals soft and prevent leaks, which is a common issue in older vehicles. It also resists heat, extending the fluid life and ensuring quiet operation of the steering system.
For those looking to extend the life of their fuel system or prepare the vehicle for storage, AMSOIL offers a range of additives and stabilizers. The AMSOIL P.i. Performance Improver gasoline additive is capable of restoring up to 14% horsepower and cleaning fuel injectors to 100% flow rate after a single tank. This is particularly beneficial for gasoline direct injection engines that may experience carbon buildup over time. Additionally, for seasonal storage, the AMSOIL Gasoline Stabilizer can keep fuel fresh for up to 12 months, preventing varnish and gum buildup. For extreme storage conditions, the AMSOIL Engine Fogging Oil can be used to coat internal engine components and prevent rust during long periods of inactivity.
