The 4.0L V6 engine in your 4-Runner is a powerhouse known for reliability, but it still requires attention to detail to maximize its lifespan. The oil capacity is 6.6 quarts when a AMSOIL Oil Filter change is included. It is crucial to refill the engine to the correct level and torque the drain plug to 30 ft/lbs after installing a new washer. For owners of vehicles with over 75,000 miles, the unique chemistry of high-mileage motor oil can help reduce oil consumption and sludge buildup, keeping the engine running more efficiently.
Transmission and Drivetrain Protection
The automatic transmission in the 2022 4-Runner, specifically the A750F and A750E models, is built for demanding tasks. Total fill capacities for these transmissions are approximately 11.3 quarts, depending on the specific setup. Switching to a fully synthetic automatic transmission fluid can significantly reduce internal friction and heat generation, which are common culprits in automatic transmission degradation. AMSOIL transmission fluids contain advanced additive packages designed to protect against wear, prevent fluid breakdown, and ensure smooth shifting even under heavy load conditions like towing trailers or navigating steep, uneven terrain. This level of protection is particularly valuable for the 4-Runner, which is often used for its intended purpose: off-roading and hauling.
Gear Lubricants and Brake Fluid
For the front and rear differentials, the 4-Runner requires GL-5 rated 75W-85 gear lubricant. Whether your model features a full-time or part-time front differential, or is equipped with a limited-slip rear differential, AMSOIL SEVERE GEAR® 75W-85 100% Synthetic Gear Lube provides the necessary extreme pressure protection. It helps control thermal runaway and protects against rust and corrosion, extending the life of the gears and bearings. The fluid also contains friction modifiers that are essential for limited-slip differentials to prevent chatter and ensure proper engagement.
Brake fluid is another critical safety component often overlooked. The 2022 4-Runner uses DOT 3 hydraulic brake fluid. Upgrading to AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid ensures that the braking system maintains consistent performance. Unlike conventional brake fluids that can absorb moisture over time, synthetic brake fluid resists moisture absorption and maintains a higher boiling point. This translates to better pedal feel, improved responsiveness, and enhanced safety during emergency stops or long descents where brake fade is a concern.
Maintenance of the cooling system is equally important for this high-output engine. The AMSOIL Propylene Glycol Antifreeze and Engine Coolant capacity is 11.1 quarts. Using a high-quality antifreeze like AMSOIL Passenger Car & Light Truck Antifreeze & Coolant protects the engine and cooling system components from corrosion and freezing. The phosphate-, nitrite-, and silicate-free formula is compatible with all cooling system metals and is safe for use with other coolant colors, offering peace of mind for long-term protection.
Additional Maintenance and Care Products
To keep your 4-Runner in peak condition beyond standard fluid changes, AMSOIL offers a range of additives and cleaners. The AMSOIL P.i.® Performance Improver gasoline additive can help restore up to 14% horsepower and clean fuel injectors, improving fuel economy and reducing the need for higher-octane fuel. For fuel system maintenance, the Upper Cylinder Lubricant Corrosion Inhibitor lubricates fuel system components and upper cylinders, ensuring smooth operation.
For vehicle owners who enjoy off-roading, the AMSOIL Mudslinger® Mud and Dirt Repellent creates a protective, non-stick layer that makes cleaning dirt and mud from the exterior much easier. Regular washing and protection can be achieved with the AMSOIL Miracle Wash Waterless Wash and Wax Spray or the High-Foam Car Shampoo. To protect the undercarriage and body panels from the elements, especially in areas with road salt, the Heavy-Duty Metal Protector and MP Metal Protector offer long-lasting corrosion resistance.
Seasonal and Storage Needs
For the vehicle owner who uses the 4-Runner seasonally or needs to store it for extended periods, proper preservation is key. The AMSOIL Gasoline Stabilizer keeps fuel fresh for up to 12 months, preventing varnish and gum buildup in the fuel system. When the engine is not in use for long durations, the Engine Fogging Oil provides a protective film on internal components to prevent rust and corrosion. These products ensure that when you are ready to hit the road again, your vehicle starts immediately and runs smoothly.
About the Vehicle
The 2022 Toyota 4-Runner is a quintessential mid-size SUV that has maintained its position as a top choice for adventure seekers and off-road enthusiasts for decades. Based on the Toyota Tacoma platform, the 4-Runner is built on a body-on-frame chassis, a design choice that prioritizes durability and towing capability over the unibody construction found in most crossover SUVs. This construction allows the vehicle to absorb the rigors of off-road trails while remaining stable for daily commuting and highway driving.
Under the hood of the 2022 model, the 4.0L 1GR-FE V6 engine delivers a robust 270 horsepower. While it may not be the most fuel-efficient engine in its class, it is celebrated for its incredible reliability and ability to pull heavy loads. This engine has powered the 4-Runner through multiple generations, and its proven track record makes it a favorite among owners who plan to put high mileage on their vehicles. The 4-Runner’s reputation for longevity is well-deserved, with many examples on the road exceeding 200,000 miles with minimal issues.
One of the standout features of the 4-Runner is its standard four-wheel-drive system. Depending on the trim level, owners can choose between a part-time system with a locking center differential or a full-time four-wheel-drive system with a locking center differential and a two-speed transfer case. The latter, often found in the TRD Pro and TRD Off-Road models, provides superior traction in challenging conditions like sand, mud, and snow, without the need to switch drive modes manually.
Despite its legendary status, the 4-Runner is not without common issues that owners should be aware of. One known problem for this generation is oil consumption, which can be exacerbated by the engine’s high-mileage wear. Using a high-mileage synthetic oil like the AMSOIL 0W-20 100% Synthetic High-Mileage Motor Oil with a superior additive package can help mitigate this issue by sealing worn piston rings and reducing blow-by. Another common concern is the potential for coolant leaks, particularly from the plastic components of the radiator and coolant reservoir. The use of AMSOIL antifreeze, which is free from phosphates and silicates that can degrade rubber hoses and seals over time, can help prolong the life of the cooling system components.
A third issue frequently reported is the development of valve rattle or noise in the engine, often caused by low oil pressure or sludge buildup in the valvetrain. Regular oil changes with a high-performance synthetic oil like the AMSOIL Signature Series 0W-20 100% Synthetic Motor Oil can keep the valvetrain clean and properly lubricated, reducing this noise and preventing long-term damage. Finally, some owners may experience shudder or harsh shifting in the automatic transmission, especially during low-speed maneuvers. Switching to a premium synthetic transmission fluid like AMSOIL Signature Series can smooth out these shifts and reduce wear on the clutch plates and bands, ensuring a more comfortable driving experience.
The 4-Runner’s market position remains strong because it offers a unique combination of truck-like durability with the comfort and convenience of an SUV. It is a versatile vehicle that can haul camping gear, tow a boat, and navigate city streets with ease. By keeping up with regular maintenance and using high-quality synthetic lubricants, owners can ensure that their 4-Runner continues to perform at the highest level, whether it is tackling a rocky trail or cruising down the highway. The investment in premium fluids and filters pays dividends in extended service intervals, better fuel economy, and a vehicle that runs smoother for years to come.
In summary, the 2022 Toyota 4-Runner is a rugged, capable, and reliable vehicle that deserves the best protection available. From the engine oil and filters to the transmission fluid and differential lubricants, AMSOIL products offer superior performance and protection that meets and often exceeds the vehicle’s requirements. By choosing the right lubricants, owners can enhance the driving experience, improve fuel economy, and extend the life of their investment.
