Engine Oil and Filtration Specifications
The heart of your 2012 Grand Vitara is the 2.4-liter, four-cylinder engine, specifically identified by the engine code J24B. To maintain optimal performance and longevity, this engine requires a specific oil change protocol. The total oil capacity for a standard oil change, including the filter replacement, is 5.1 quarts. It is crucial to adhere to the correct fill level, as both overfilling and underfilling can lead to engine damage, foaming, or oil starvation.
AMSOIL Signature Series 5W-30 100% Synthetic Motor Oil is formulated to flow freely in sub-zero temperatures while maintaining a protective film at high operating temperatures. This ensures that critical engine components are lubricated instantly upon startup, reducing wear during the most damaging phase of the engine cycle. The recommended oil grade is 5W-30, which works effectively in all temperature ranges. For owners of the Grand Vitara, choosing between the various synthetic options depends on driving habits and the vehicle’s mileage.
The AMSOIL 5W-30 100% Synthetic High-Mileage Motor Oil is particularly beneficial for vehicles with over 75,000 miles. This formulation contains unique chemistry designed to condition aging seals, which helps reduce oil consumption and leaks while restoring horsepower and reducing sludge by up to 67%. For new engines or those seeking maximum durability, the AMSOIL Signature Series 5W-30 100% Synthetic Motor Oil offers the highest level of protection, guaranteeing up to 25,000 miles or one year of service. Alternatively, the AMSOIL Extended-Life 5W-30 100% Synthetic Motor Oil and AMSOIL OE 5W-30 100% Synthetic Motor Oil provide robust protection for 20,000 miles and OEM-level performance respectively.
Equally important is the filtration system. The recommended oil filter for this vehicle is the AMSOIL Oil Filter (EA15K09). This filter offers filtering efficiency of 99 percent at 20 microns, significantly higher than standard paper filters. Its increased capacity allows it to hold more small, wear-causing contaminants, reducing the frequency of clogging and ensuring a consistent flow of clean oil to the engine. Proper filtration is essential to prevent abrasive particles from circulating through the oil galleries of the J24B engine.
Transmission and Transfer Case Fluids
The 2012 Suzuki Grand Vitara was available with both automatic and manual transmissions, and the correct fluid selection is vital for smooth power delivery. For the 4-speed automatic transmission, the total fill capacity is 7.6 quarts, with an initial fill of 2.6 quarts. The vehicle requires a fluid equivalent to ATF 3317 or ATF 3309 specifications. Using a high-quality AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is critical for preventing shudder, ensuring smooth shifts, and protecting against the heat generated during towing or extended highway driving.
The AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is engineered to withstand the rigors of heavy towing and elevated temperatures. It remains fluid in sub-zero conditions and provides reserve protection during heavy use. For a more budget-friendly option that still offers superior protection, the AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid guards against sludge and promotes shudder-free shifts.
For manual transmission models, the vehicle utilizes a 5-speed gearbox requiring GL-4 lubrication. While SAE 75W-80 is the preferred specification, 75W-90 or 75W-85 are acceptable alternatives. The total capacity for the manual transmission is approximately 4 pints. The AMSOIL 75W-90 Manual Transmission & Transaxle Gear Lube is specifically formulated to protect brass synchronizers and inhibit rust and corrosion, ensuring precise gear selection even in cold weather.
Regarding the 4WD system, the Grand Vitara features a transfer case that requires GL-5 lubrication. The capacity varies depending on whether the unit includes a transfer switch or is without one, generally ranging around 3.2 to 3.4 pints. Both the front and rear differentials also require GL-5 gear lube, with capacities of approximately 2.1 pints for the front and 1.7 to 2.3 pints for the rear, depending on the specific configuration (manual or automatic transmission). For these heavy-duty applications, the AMSOIL SEVERE GEAR 80W-90 100% Synthetic Gear Lube or AMSOIL SEVERE GEAR 75W-90 100% Synthetic Gear Lube provide advanced protection against wear and thermal runaway. The AMSOIL SEVERE GEAR 75W-110 100% Synthetic Gear Lube is another robust option for limited-slip applications or extreme load conditions.
Cooling, Braking, and Additional Protection
Maintaining the cooling system is essential for the J24B engine’s longevity. The capacity for AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is 7.6 quarts for automatic transmission models and 7.7 quarts for manual transmission models. The factory fill is typically an ethylene glycol-based antifreeze. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a 50/50 pre-mix that exceeds OEM requirements, protecting all cooling system metals, gaskets, and hoses for up to 150,000 miles. For those who prefer a concentrated solution that offers enhanced safety and even longer service intervals, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant is a premium choice that can last up to 150,000 miles in passenger cars and light trucks.
Brake safety cannot be compromised. The hydraulic AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid should be used to maintain a high boiling point, prevent vapor lock, and avoid brake fade. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid offers excellent responsiveness for ABS and traction control systems. It maintains a stable viscosity across a wide temperature range, ensuring consistent pedal feel and performance in all weather conditions.
To further protect and enhance the vehicle’s performance, AMSOIL offers fuel additives and lubricants. The AMSOIL P.i.® Performance Improver Gasoline Additive is highly effective at restoring fuel injectors, improving fuel economy, and preventing carbon buildup. For storage periods, the AMSOIL Gasoline Stabilizer keeps fuel fresh for up to 12 months, while the AMSOIL Engine Fogging Oil prevents internal rust during long-term inactivity.
