One of the most critical aspects of maintaining your 2012 GMC Yukon is ensuring the engine receives the correct lubrication. The 5.3L V8 engine requires a robust oil change to handle the stresses of driving, whether on highways or during towing. The vehicle requires a capacity of 6.0 quarts when changing the oil and filter. It is important to check the oil level after refill and to torque the oil drain plug to 18 ft/lbs. For those using E85 or M85 fuels, it is recommended to use an oil of the appropriate viscosity and to extend oil drains only through oil analysis to ensure safety.
Engine and Filter Maintenance
Choosing the right motor oil depends on the age and condition of your vehicle. For newer engines or those seeking maximum performance, the AMSOIL Signature Series 5W-30 100% Synthetic Motor Oil stands out with its ability to provide 75% more engine protection against horsepower loss and wear. This oil is trusted by professional engine builders and offers a guaranteed protection interval of up to 25,000 miles or one year. For drivers who prioritize cleaning power, the AMSOIL Extended-Life 5W-30 100% Synthetic Motor Oil offers 37% more cleaning capability than OE synthetic motor oil, helping to keep the engine running smoother for longer periods.
If your vehicle is approaching the typical factory service interval or you prefer a cost-effective solution, the AMSOIL OE 5W-30 100% Synthetic Motor Oil is an excellent option. It fights sludge and deposits effectively while providing protection that meets or exceeds GM dexos1 Gen 2 specifications. Additionally, for Yukons with over 75,000 miles on the odometer, the AMSOIL 5W-30 100% Synthetic High-Mileage Motor Oil utilizes unique chemistry with boosted detergents and dispersants. This formulation reduces sludge by 67% and helps engines last longer by maintaining better performance and cleaner internals.
Filtration is equally important. The WIX Oil Filter (57060) is recommended for this vehicle. Its premium media offers improvements over original equipment manufacturer-branded filters, ensuring that contaminants are effectively removed from the oil stream to extend the life of the lubricants and the engine. Pairing this filter with a high-quality synthetic oil creates a comprehensive protection system for your drivetrain.
Transmission and Drivetrain Protection
The automatic transmission in the 2012 GMC Yukon, specifically the 6L80 model, benefits significantly from synthetic transmission fluid. Depending on the specific configuration (Heavy Duty 6L80 or Light Duty 6L80), the total fill capacities range from 12.2 quarts to 12.4 quarts, with an initial fill of approximately 6 quarts. Using the AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid provides the ability to withstand heavy towing and elevated temperatures, which are common for this full-size SUV. This fluid remains fluid in sub-zero temperatures, ensuring reliable shifts in winter conditions.
For those looking for a reliable OE-grade alternative, the AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid offers robust protection against wear while maintaining fuel efficiency. Both fluids are designed to protect the transmission from sludge and temperature-related problems, driving your vehicle with confidence.
The differential and transfer case lubrication is vital for four-wheel-drive models. The transfer case (BW4485-NR3) requires a capacity of 3 pints, while front and rear differentials vary based on the specific gear set (such as 9.25 RG, 10.5 RG, or 8.6 RG). The recommended lubricant for these components is the AMSOIL SEVERE GEAR® 75W-90 100% Synthetic Gear Lube. This synthetic gear lube controls thermal runaway, protects against rust and corrosion, and helps reduce operating temperatures. It contains friction modifiers essential for limited-slip applications, ensuring smooth power delivery to the wheels and extending the life of the seals and equipment.
Other Essential Fluids
Beyond the engine and drivetrain, other fluid systems require attention to ensure the vehicle operates safely. The cooling system, with a capacity of 18.3 quarts, needs reliable antifreeze protection. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is an ethylene glycol 50/50 pre-mix that protects all cooling system metals, gaskets, and hoses for up to 150,000 miles. It is free of phosphates, nitrates, nitrites, silicates, borates, and amines, making it compatible with all other coolant colors.
For maximum cooling capacity, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant is a concentrated option that requires mixing with distilled water. This fluid greatly surpasses standards for metallic corrosion and erosion, offering protection up to 150,000 miles or 5 years in light truck applications. In the braking system, the AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid provides excellent ABS responsiveness and stable viscosity over a wide temperature range, which is critical for consistent braking performance.
The power steering system in the Yukon utilizes a multi-vehicle fluid. The AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid reduces friction and helps seals remain soft to prevent leaks. It resists heat for long fluid life and provides strong anti-wear protection, ensuring quiet operation and preventing damage to the steering pump.
Additional Protection and Care
To maintain peak engine performance, the AMSOIL P.i.® Performance Improver Gasoline Additive is highly recommended. This additive restores up to 14% horsepower and cleans GDI fuel injectors to 100% flow rate, improving fuel economy and reducing the need for higher-octane fuel. It is compatible with capless fuel systems and helps control pre-ignition knock.
For seasonal storage, the AMSOIL Gasoline Stabilizer keeps fuel fresh for up to 12 months and protects against varnish and gum buildup. The AMSOIL Engine Fogging Oil is ideal for protecting internal engine components during long periods of inactivity. If your vehicle has seen significant miles, the AMSOIL Upper Cylinder Lubricant Corrosion Inhibitor lubricates the fuel system and upper cylinders, offering protection for high-mileage engines.
Vehicle care extends to the exterior as well. The AMSOIL High-Foam Car Shampoo is a bucket-wash and foam-cannon capable formula that breaks down contaminants gently. For a quick wash, the AMSOIL Miracle Wash Waterless Wash and Wax Spray requires just a spray and wipe, leaving a protective finish that repels dust and dirt. To clean brake parts without disassembly, the AMSOIL Brake and Parts Cleaner quickly removes oil and grease, helping to eliminate brake squeal. For tough grime on engine surfaces, the AMSOIL Engine Degreaser provides a professional-strength formula that washes off easily. The AMSOIL Glass Cleaner cuts through grease without streaks, and the AMSOIL Interior Detailer (Light Lemon or Scent Free) offers multi-surface use with UV protection and odor elimination.
