Engine Oil and Filter Specifications
The 2016 Kia SOUL with the 1.6L engine code [2] A is designed to run on SAE 5W-20 motor oil, which is the preferred viscosity for all temperatures. The total fluid capacity for an oil change, including the filter replacement, is 3.8 quarts. After refilling, it is essential to check the oil level to ensure accuracy. When replacing the drain plug, a torque specification of 25 to 32 ft/lbs should be applied to prevent leaks or damage to the threads.
Owners have four distinct choices for synthetic motor oil, each tailored to different needs. The Signature Series 5W-20 is the top-tier option, providing up to 25,000 miles of protection and superior resistance against horsepower loss. For those seeking a balance between performance and value, the Extended-Life version offers 20,000 miles of coverage with enhanced cleaning properties. The OE (Original Equipment) line matches the specifications required by the manufacturer while being fully synthetic, and the High-Mileage variant is specifically designed for vehicles with over 75,000 miles on the odometer to reduce consumption and sludge.
Filtration is equally critical. The AMSOIL Oil Filter is highly recommended for its extended service life and ability to capture smaller contaminants that can cause wear. It offers 99% efficiency at 20 microns. For those who prefer a premium aftermarket alternative, the WIX Oil Filter is also a valid choice, known for exceeding OEM performance standards.
Transmission and Cooling System Care
The 2016 Kia SOUL typically comes with a 6-speed automatic transmission, model code A6GF1. The total fill capacity for this transmission is 7.7 quarts. Maintaining this fluid is vital for smooth shifting and preventing costly internal wear. AMSOIL offers two primary synthetic transmission fluids for this application. The Signature Series Fuel-Efficient fluid is built to withstand the rigors of heavy towing, elevated temperatures, and challenging terrain, making it ideal for severe driving conditions. The OE Fuel-Efficient fluid provides excellent wear protection and is suitable for standard driving scenarios.
Proper cooling is another area where synthetic fluids excel. The cooling system requires 5.4 quarts if equipped with the MTXL radiator or 5.3 quarts with the ATXL radiator. AMSOIL Antifreeze & Coolant is an ethylene glycol-based 50/50 pre-mix that protects all metals, gaskets, and hoses in the cooling system. It is free from phosphates, nitrates, and other additives that can cause corrosion, ensuring a long service interval of up to 150,000 miles or 5 years. For those who prefer a concentrated solution, the Propylene Glycol Antifreeze offers similar protection and can be mixed with distilled water to achieve the desired freeze and boil-over points.
Brake Fluid and Seasonal Maintenance
Brake system safety cannot be compromised. The 2016 Kia SOUL utilizes a hydraulic brake fluid system that is compatible with DOT 3 specifications. The AMSOIL DOT 3 and DOT 4 Synthetic Brake Fluid is an excellent choice, offering stable viscosity across a wide temperature range. This ensures responsive braking and optimal ABS and traction control performance. Replacing this fluid helps prevent moisture buildup, which can lead to corrosion within the brake lines and calipers.
For vehicle owners who do not drive daily or store their cars seasonally, AMSOIL offers several preservation products. The Gasoline Stabilizer can keep fuel fresh for up to 12 months, protecting against varnish and gum buildup caused by ethanol corrosion. Additionally, the Engine Fogging Oil is designed to prevent internal rusting during long periods of inactivity, making it ideal for seasonal storage. These products ensure that when the vehicle is ready to run again, the engine and fuel system are in pristine condition.
Using high-quality fluids from AMSOIL provides a comprehensive solution for the 2016 Kia SOUL. By utilizing these synthetic lubricants, drivers can achieve better fuel economy, reduced engine wear, and increased confidence in their vehicle’s performance regardless of the weather or driving conditions.
