The engine lubrication requirements for the 2012 Hyundai Santa Fe are critical for preventing premature wear. The 2.4-liter four-cylinder engine is best served by a 5W-20 viscosity grade. While the vehicle can operate with 10W-30 in temperatures above -18°C, 5W-20 is the preferred grade for all temperature ranges. The system holds 4.9 quarts of oil when the filter is changed. It is important to torque the oil drain plug to 29 foot-pounds and always install a new washer on the drain bolt to prevent leaks. After refilling, checking the oil level is essential to ensure the correct amount is present for proper lubrication.
AMSOIL offers a range of motor oils tailored to the specific needs of this engine. For owners seeking the absolute maximum protection and extended drain intervals, the Signature Series 5W-20 is the top choice. It is engineered to provide 75% more engine protection against horsepower loss and wear, ensuring the engine remains clean and efficient for up to 25,000 miles or one year. For those who prefer a slightly shorter service interval but still want synthetic benefits, the Extended-Life 5W-20 offers 20,000 miles of protection with enhanced cleaning power. If you are looking for a product that outperforms conventional oils and meets OEM standards, the OE 5W-20 is an excellent choice. Additionally, for vehicles with more than 75,000 miles, the High-Mileage 5W-20 features unique chemistry with boosted detergents to clean sludge and reduced sludge by 67% in testing, helping older engines perform better.
Filtering the oil is just as important as the oil itself. The recommended filter for this vehicle is the AMSOIL Oil Filter, model EA15K20. This filter is designed to provide 99% filtering efficiency at 20 microns, allowing for lower restriction and keeping engine parts well-lubricated. It has a greater capacity for small, wear-causing contaminants compared to competing filters, which helps reduce engine wear and extends service life. Alternatively, the WIX Oil Filter, model 51334-EA, is a premium option that offers improvements over original equipment manufacturer-branded filters.
Beyond the engine, the transmission of the 2012 Santa Fe requires specialized attention. The vehicle utilizes a 6-speed automatic transmission (A6MF2) that requires a total fill of 7.5 quarts. For this component, the AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is highly recommended. It is built to withstand the rigors of heavy towing, elevated temperatures, and challenging terrain while remaining fluid in sub-zero conditions. This provides reserve protection during heavy use and abuse. For those seeking a more budget-friendly option, the OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid also offers reliable protection against wear for everyday driving conditions.
Proper cooling system maintenance is vital for the longevity of the 2012 Hyundai Santa Fe. The cooling system requires a total of 6.9 quarts if equipped with the MTXL6 radiator or 7 quarts if equipped with the ATXL6. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a pre-mixed, 50/50 formulation that protects all cooling system metals, gaskets, and hoses. It features a unique poly-organic acid (OAT) formulation and is free of phosphates, nitrates, and silicates, ensuring compatibility with all other antifreeze colors. For those who prefer a concentrated option that requires mixing with distilled or high-quality water, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers protection up to 150,000 miles or five years and greatly surpasses standards for metallic corrosion and erosion.
The braking system and power steering components also benefit from high-performance fluids. For the hydraulic brake fluid, the AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is recommended. It ensures excellent ABS and traction-control responsiveness while maintaining a stable viscosity over a wide temperature range. For the power steering system, the AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid is ideal. It reduces friction, keeps seals soft to prevent leaks, and resists heat for long fluid life, ensuring quiet operation and strong anti-wear protection.
