The engine is the heart of your vehicle, and for the 2012 Jeep Patriot with the 2.4L engine code [B] ED3 C, the requirements are specific regarding viscosity and capacity. The engine oil capacity, when including a filter change, is 4.5 quarts. It is crucial to check the oil level after refill to ensure the correct amount is present, as overfilling or underfilling can lead to performance issues. The drain plug should be torqued to 30 ft/lbs to ensure a secure seal without damaging the threads. For this application, the recommended viscosity is 5W-20 for all temperature conditions, ensuring proper flow during cold starts and adequate film strength at operating temperatures. Drivers who prefer the ultimate in protection might choose the Signature Series, while those with higher mileage might benefit from the High-Mileage formulation, which includes boosted detergents to clean sludge and reduce oil consumption.
Fluids are not limited to the engine block; the transmission system in the Patriot demands specialized attention. The automatic transmission utilizes CVT2 fluid, requiring a total fill of 8.6 quarts or an initial fill of 7.4 quarts. The transmission fluid plays a vital role in managing the frictional properties between metal components, and using a 100% synthetic CVT Fluid helps maximize the efficiency and longevity of the Continuously Variable Transmission. For vehicles with manual transmissions or those utilizing Multi-ATF specifications, AMSOIL OE and Signature Series fluids provide the necessary protection against wear, sludge, and extreme heat, ensuring smooth shifts even under heavy loads or in challenging terrain.
Cooling system maintenance is equally critical for the 2012 Patriot. The cooling system holds approximately 7.2 quarts of AMSOIL Passenger Car & Light Truck Antifreeze & Coolant. AMSOIL offers both ethylene glycol-based pre-mixed AMSOIL Propylene Glycol Antifreeze and Engine Coolant and a concentrated propylene glycol option, both formulated to protect all cooling system metals, gaskets, and hoses. These antifreeze formulations are free of phosphates, nitrates, and silicates, meeting or exceeding original equipment manufacturer requirements. Proper cooling system maintenance prevents overheating, which is particularly important for engines subjected to stop-and-go traffic or towing, ensuring the engine operates within its optimal temperature range.
The differential and transfer case also require regular lubrication to prevent premature wear. The rear differential requires approximately 1.1 pints of SAE 80W-90 AMSOIL SEVERE GEAR 80W-90 100% Synthetic Gear Lube, while the transfer case has a similar capacity. For these applications, AMSOIL SEVERE GEAR® 80W-90 is recommended. This AMSOIL 100% Synthetic Gear Lube contains friction modifiers suitable for limited-slip applications and helps reduce operating temperatures, thereby extending the life of the seals and gears. The drain and fill plugs should be torqued to 24 ft/lbs to maintain a leak-free system. Using a high-quality AMSOIL synthetic Gear Lube helps control thermal runaway and protects against rust and corrosion, which is essential for vehicles that see regular use in wet or muddy conditions.
AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is a vital safety component that is often overlooked. The Patriot utilizes DOT 3 hydraulic brake fluid meeting MS-4574 specifications. AMSOIL Brake Fluid is designed to provide excellent responsiveness for ABS and traction control systems. AMSOIL 100% Synthetic Brake Fluid resists moisture absorption better than conventional fluids, maintaining a stable viscosity over a wide temperature range and preventing brake fade under heavy use. This ensures that the braking system remains reliable and responsive, providing peace of mind in emergency situations.
