The 2022 Toyota Avalon equipped with the 3.5L 6-cylinder engine (code 2GR-FKS 9) is a powerhouse of smooth performance and long-term durability. However, to maintain that factory-fresh feel and ensure the vehicle lasts for hundreds of thousands of miles, utilizing premium synthetic lubricants is essential. The Avalon’s engine, transmission, and braking systems rely on specific fluid characteristics that standard conventional oils often cannot provide for extended periods. Using high-quality AMSOIL products allows you to maximize fuel economy, protect against wear during extreme temperatures, and extend service intervals without sacrificing engine performance.

Engine Oil and Filtration
The heart of the 2022 Toyota Avalon is the 3.5L V6 engine, which requires 0W-20 viscosity oil for optimal fuel economy and cold-weather starting. The manufacturer specifies a total capacity of 5.7 quarts when the filter is replaced. While many drivers stick to conventional oils, switching to synthetic lubricants offers significant advantages. AMSOIL synthetic motor oils are formulated to resist break down and volatility, meaning less oil consumption and better protection for the engine components that are most prone to wear. The AMSOIL Signature Series 0W-20 100% Synthetic Motor Oil product, for instance, is tested to provide superior horsepower retention and reduces the rate of engine wear, which is critical for keeping the V6 smooth for the long haul.
Choosing the right oil filter is just as important as the oil itself. A standard filter may only offer minimal resistance to flow, but the AMSOIL Oil Filter provides extended service life that matches the synthetic oil’s capabilities. It captures smaller wear-causing contaminants more effectively than typical filters, ensuring that the oil remains clean even after thousands of miles of operation. For those who prefer to stick with established OEM-style brands, the WIX Oil Filter is also an excellent recommendation, offering premium media that surpasses the original equipment filters in efficiency.
Transmission and Differential Care
The Avalon is powered by an 8-speed automatic transmission (UA80E), which relies on specialized fluid to manage the complex shifting of gears and the transfer of power. The total fill capacity for this transmission is 7.9 quarts. Standard fluid can sometimes degrade under the stress of heavy towing or driving in severe conditions, leading to hesitation or rough shifts. AMSOIL transmission fluids are designed to withstand these rigors, maintaining their viscosity and protective properties even when temperatures soar or drop significantly.
The 2022 Avalon also features a rear differential that requires GL-5 rated lubricant. Using the correct AMSOIL SEVERE GEAR 75W-85 100% Synthetic Gear Lube is vital to prevent wear and thermal runaway, a condition where the fluid breaks down due to excessive heat. AMSOIL SEVERE GEAR is formulated to handle these extreme conditions, containing friction modifiers for limited-slip applications if your vehicle is equipped with one. This fluid helps reduce operating temperatures and extends the life of the seals and gears within the differential.
Cooling and Braking Fluids
A robust cooling system is necessary to keep the 3.5L engine running at its optimal temperature, especially during the hot summer months or when towing. The cooling system holds 9.1 quarts of AMSOIL Passenger Car & Light Truck Antifreeze & Coolant. This product is an ethylene glycol 50/50 pre-mix that exceeds OEM requirements, protecting against corrosion, rust, and freezing. It is compatible with all cooling system metals and hoses, ensuring no damage to seals over time. Alternatively, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant is a concentrated option that offers even longer service intervals.
Safety is paramount, and the braking system must always perform reliably. The Avalon requires DOT 3 or DOT 4 AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid. This fluid provides a stable viscosity over a wide temperature range, ensuring consistent pedal feel and responsive ABS activation. This synthetic fluid resists boiling, which is a common issue with conventional fluids that can lead to brake fade during hard stopping or steep descents.
About the Vehicle
The 2022 Toyota Avalon represents the pinnacle of Toyota’s sedan lineup, serving as a flagship model designed for those who prioritize comfort, refinement, and reliability. Built on the Toyota New Global Architecture (TNGA) platform, the Avalon benefits from a lower center of gravity, which enhances handling and stability without sacrificing the smooth, floaty ride characteristic of a large sedan. The vehicle is powered by the naturally aspirated 3.5L 2GR-FKS V6 engine, a proven powerplant known for its smooth power delivery and efficiency. This engine produces a healthy amount of horsepower, making the Avalon a capable cruiser that handles highway merging and passing maneuvers with ease. It is widely regarded as a comfortable, quiet, and spacious vehicle, often favored by families and commuters who drive long distances frequently.
One of the primary reasons owners choose the Avalon is its reputation for exceptional longevity. It is not uncommon for these sedans to reach well over 200,000 miles when properly maintained. However, to achieve this level of durability, owners must address specific maintenance needs that arise as the vehicle accumulates mileage. The 2GR-FKS engine, while robust, can benefit from high-quality synthetic oils to prevent carbon buildup and ensure consistent oil pressure. Additionally, the suspension components, which are tuned for a plush ride, may experience wear over time, but the vehicle’s chassis design generally remains solid. Owners should also be mindful of the electronic systems and infotainment components, as these can sometimes be the first signs of age in the vehicle’s interior. Regular fluid changes using premium lubricants help mitigate the effects of time and heat on these systems, keeping the Avalon running like new for years to come.
Despite its reputation for reliability, the Avalon does have a few known areas of concern that can be mitigated with the right maintenance strategy. One common issue is the potential for oil consumption in higher-mileage engines, which can be addressed by using the AMSOIL 0W-20 100% Synthetic High-Mileage Motor Oil to help seal engine rings and reduce burn-off. Another known problem in some V6 engines of this era is carbon buildup on the intake valves, which can affect performance and fuel economy; this is where the use of AMSOIL P.i. Performance Improver gasoline additive can be highly beneficial in restoring injector flow and reducing knock. Some owners have reported issues with the 8-speed automatic transmission shifting erratically or hesitating, particularly in colder weather or under load; upgrading to the AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid helps maintain fluid viscosity and protects against the wear that leads to these shifting problems. Finally, the cooling system can sometimes suffer from premature degradation of hoses or radiator caps in older models, leading to leaks or overheating; using a high-quality antifreeze like AMSOIL Passenger Car & Light Truck Antifreeze can provide superior corrosion protection and extend the life of the entire cooling system components.
Ultimately, the 2022 Toyota Avalon 3.5L is a vehicle that rewards conscientious ownership. By selecting the correct AMSOIL products for its specific requirements, drivers can ensure that their Avalon continues to provide the smooth, reliable, and comfortable driving experience it was designed for, regardless of the conditions it faces on the road.
