The 2016 Lexus GS F is a high-performance luxury sedan powered by the naturally aspirated 5.0-liter 2UR-GSE V8 engine. This powerhouse delivers 467 horsepower and is designed for drivers who demand precision handling alongside everyday drivability. Because the engine is built for aggressive driving and high-rpm performance, the lubricants you select play a critical role in maintaining engine longevity and power delivery. Using the correct oil viscosity and high-quality filter ensures that the engine operates smoothly under extreme thermal stress, while appropriate transmission and differential fluids keep the power delivery to the rear wheels seamless.

Proper lubrication begins with the engine. The 2UR-GSE engine requires a precise viscosity to ensure rapid oil flow during cold starts while maintaining film strength at operating temperatures. For the 2016 Lexus GS F, SAE 5W-30 is the best choice for a balance of fuel economy and starting performance. The engine oil capacity is 9.3 quarts when the filter is replaced. After refilling, it is critical to check the oil level to ensure accuracy. Additionally, the drain plug should be torqued to 30 ft/lbs, and a new washer should always be installed on the drain bolt to prevent leaks.
When selecting your oil, the Signature Series 5W-30 stands out as the top recommendation for owners seeking the highest level of protection. It is designed to provide 75% more engine protection against horsepower loss and wear compared to industry standards. For those who prefer a slightly different service interval or cleaning profile, the Extended-Life 5W-30 offers 37% more cleaning power and protects against low-speed pre-ignition (LSPI). The OE 5W-30 is another excellent option that outperforms conventional oils and is trusted by professional engine builders for its ability to fight sludge. All these oils are 100% synthetic, ensuring stability in extreme heat and flow in extreme cold.
The cooling system in this luxury sedan requires robust protection to handle the heat generated by the high-output engine. The 2016 Lexus GS F has a coolant capacity of 11.9 quarts. AMSOIL offers two excellent choices for the cooling system. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a pre-mixed, phosphate- and silicate-free formula that protects all cooling system metals, gaskets, and hoses. For those who prefer to mix their own, the AMSOIL Propylene Glycol Antifreeze offers a highly concentrated alternative that can be diluted for maximum protection up to 150,000 miles or 5 years.
Maintaining the transmission is equally vital for preserving the smooth power delivery of the GS F. The vehicle utilizes an AA80E 8-speed automatic transmission. The total fill capacity is 11.8 quarts, with an initial fill of 3.9 quarts. For maximum protection, the Signature Series Fuel-Efficient ATF is recommended. This fluid remains fluid in sub-zero temperatures and withstands the rigors of heavy towing and elevated temperatures. Alternatively, the OE Fuel-Efficient ATF provides a cost-effective, yet high-performance synthetic option that protects against wear and maintains shift quality.
The differential lubrication requires specific attention due to the limited-slip nature of the rear axle. The rear differential requires 3 pints of GL-5 lubricant, while the torque transfer module requires Toyota automatic transmission fluid Type WS. For the rear differential, the AMSOIL SEVERE GEAR® 75W-85 is the ideal replacement. It contains friction modifiers suitable for limited-slip applications and helps reduce operating temperatures while preventing rust and corrosion. This fluid is designed to control thermal runaway, a common issue in performance differentials.
Safety and maintenance extend to the braking system as well. The 2016 Lexus GS F uses a hydraulic brake fluid system requiring DOT 3 or DOT 4 specification. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid provides a stable viscosity over a wide temperature range. This stability ensures excellent ABS and traction-control responsiveness, giving the driver confidence during aggressive braking maneuvers.
Vehicle Background
The 2016 Lexus GS F represents the pinnacle of the GS sedan lineup, bridging the gap between a comfortable luxury cruiser and a high-performance track machine. Introduced to compete directly with European sports sedans, the GS F is distinguished by its naturally aspirated 5.0-liter V8 engine, a rarity in an era where manufacturers were increasingly turning to forced induction and smaller displacement four-cylinder engines. This engine, code 2UR-GSE, produces 467 horsepower and 389 lb-ft of torque, offering a linear and responsive power delivery that many enthusiasts prefer over turbocharged alternatives.
Designed with a rear-wheel-drive layout, the GS F features a robust chassis developed on the Lexus LFA platform, providing exceptional rigidity and handling characteristics.
