The 2008 Mitsubishi Lancer equipped with the 2.0L 4-cylinder turbocharged engine (Engine Code 4B11 V) is a spirited compact sedan that demands high-performance lubricants to maintain its power and longevity. Proper fluid selection is critical for this vehicle, particularly because the turbocharged engine operates under higher thermal and mechanical stress than naturally aspirated units. Using the correct viscosity and high-quality synthetic base stocks ensures that oil film strength is maintained during hard acceleration and that critical components like turbocharger bearings are adequately lubricated. Beyond the engine, the vehicle’s specific transmission types, cooling requirements, and hydraulic systems also rely on specialized formulations to prevent premature wear and maintain optimal driving dynamics.

The engine in the 2008 Mitsubishi Lancer is a turbocharged four-cylinder unit that benefits significantly from synthetic technology. The factory-recommended oil grade is 5W-30, with a total capacity of 5.4 quarts when the oil filter is also replaced. Maintaining the correct oil level is vital, as the turbocharger relies heavily on a steady flow of clean oil for cooling and lubrication. After refilling, owners should check the oil level and ensure the drain plug torque is within the 26-32 ft/lbs specification. The AMSOIL Signature Series 5W-30 100% Synthetic Motor Oil is particularly well-suited for this application, offering superior shear stability and thermal oxidation resistance. This helps protect the turbocharger bearings from the intense heat generated during spirited driving or track use, preventing premature wear that can lead to catastrophic engine failure.
Filtering the oil is just as important as the oil itself. The AMSOIL Oil Filter (EA15K20-EA) is engineered to provide extended service life. It features a higher capacity for small, wear-causing contaminants compared to many competitors, ensuring that the oil remains clean throughout the long synthetic interval. For those who prefer original equipment manufacturer (OEM) style filtration, the WIX Oil Filter (Part #57092-EA) is also a compatible option. These filters feature premium media that offers improvements over standard OEM-branded filters, providing a high filtration efficiency that keeps engine parts well-lubricated and reduces internal wear.
Transmission and Differential Care
The 2008 Lancer’s transmission system requires precise fluid selection depending on whether the vehicle is equipped with the TC-SST dual-clutch transmission or a manual gearbox. For the TC-SST, the fluid capacity for a total fill is 8 quarts, while the initial fill requires 5.8 quarts. Using the correct fluid is crucial to prevent shudder and ensure smooth clutch engagement. AMSOIL 100% Synthetic DCT Fluid is designed to prevent shudder and offers outstanding wear protection in extreme heat and cold. It is specifically formulated to meet the demanding requirements of Mitsubishi’s dual-clutch systems.
For the rear limited-slip differential or Torq Mechanism, the capacity is quite small, at 1.2 pints. This area benefits greatly from high-performance lubricants. AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is an excellent choice here as well, providing the necessary protection against the rigors of heavy towing and elevated temperatures. It remains fluid in sub-zero temperatures and offers reserve protection during heavy use. Alternatively, the AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid provides a cost-effective option that guards against leaks and promotes smooth, shudder-free shifts.
Cooling System and Brake Fluid
The cooling system for the 2008 Lancer holds 7.4 quarts of AMSOIL Passenger Car & Light Truck Antifreeze & Coolant. Maintaining the proper mixture is essential to prevent overheating, which can be a significant risk for turbocharged engines. This formulation is a unique poly-organic acid (OAT) that allows for use in a wide variety of vehicles and offers protection up to 150,000 miles or 5 years. It is phosphate-, nitrate-, and silicate-free, compatible with all other coolant colors, and protects all cooling system metals, gaskets, and hoses. For those who prefer a concentrated product that requires mixing with distilled water, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant provides even longer service life, protecting against metallic corrosion and erosion far beyond standard industry standards.
Brake fluid safety cannot be overlooked. The 2008 Lancer utilizes a DOT 3 hydraulic brake fluid. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid provides excellent responsiveness for both ABS and traction-control systems. Its stable viscosity over a wide temperature range ensures consistent pedal feel and reliable stopping power, regardless of driving conditions. This synthetic formulation prevents the moisture absorption issues common with conventional brake fluids, which can lead to brake fade and internal corrosion.
Additional Fluids and Seasonal Protection
AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid also plays a role in the overall health and comfort of the vehicle. It reduces friction and helps seals remain soft to prevent leaks. It is formulated for quiet operation and offers strong anti-wear protection, resisting heat for long fluid life. For owners who plan to store their vehicle during winter months or extended periods of inactivity, AMSOIL Gasoline Stabilizer is highly recommended to keep fuel fresh for up to 12 months. This additive protects against varnish and gum buildup, fighting ethanol corrosion that can clog fuel systems and damage engines.
