Understanding the specific needs of the 2012 Lincoln MKS helps you appreciate why using premium synthetic lubricants is a wise investment. The 3.7-liter V-6 engine requires a precise viscosity of 5W-20, with a total capacity of 5.5 quarts when changing the oil filter. This capacity ensures that the oil pump can adequately circulate lubricant to all critical components, including the cylinder heads, camshafts, and crankshaft bearings. Using oil that matches this specification is vital for maintaining oil pressure and ensuring the turbocharger (if equipped) or the standard valvetrain receives adequate flow. Furthermore, the transmission fluid capacity for the 6-speed automatic is significant at 10.9 quarts for a total fill, making the choice of a high-quality synthetic fluid even more critical for the longevity of the transmission.
The drivetrain components, including the transfer case and rear differential, also have specific requirements. The transfer case requires 1.1 pints of SAE 75W-140 synthetic gear lubricant, while the rear differential needs 2.4 pints of SAE 80W-90 meeting Ford specifications. These gears operate under high friction and heat, and the specialized synthetic gear lubes recommended provide the necessary extreme pressure protection to prevent wear and pitting. For the cooling system, a total capacity of 11.1 quarts is required, emphasizing the need for a coolant that protects against corrosion and overheating. Brake fluid maintenance is equally important, with DOT 3 or DOT 4 standards required to ensure the hydraulic system responds instantly to pedal input.
Why Proper Lubrication Matters
Using the correct AMSOIL products goes beyond simply meeting manufacturer specifications; it is about achieving peak performance and protection that standard oils cannot provide. Synthetic motor oils like the Signature Series and Extended-Life options offer superior resistance to oxidation and thermal breakdown. This means the oil maintains its viscosity and protective properties even under the extreme heat generated by stop-and-go traffic or towing. The high-temperature stability of these oils prevents sludge formation, a common issue in vehicles with older engines or those subjected to severe service, thereby extending the engine’s operational life.
Similarly, the transmission and gear lubricants are engineered to handle the rigors of heavy loads and extreme temperatures. Synthetic automatic transmission fluids remain fluid in sub-zero temperatures, ensuring smooth shifting during cold starts, while resisting shear and maintaining viscosity in high heat. This balance is crucial for the durability of the torque converter and transmission bands. The gear lubes, with their advanced friction modifiers, reduce operating temperatures and protect against rust and corrosion, ensuring the limited-slip differentials and gears operate smoothly and quietly. By using these specialized fluids, owners can mitigate the risk of costly repairs and maintain the vehicle’s smooth driving character.
