Maintaining your 2018 Toyota LAND CRUISER with the 5.7L 8-cylinder engine requires more than just following a standard schedule; it demands the use of fluids engineered to handle the specific thermal and mechanical stresses of this robust powertrain. The 3UR-FE engine is renowned for its durability and capacity for long-distance travel, but these very qualities mean it relies heavily on high-quality lubrication to prevent wear, manage heat, and ensure smooth operation under heavy loads. Proper fluid selection is critical for preserving the engine’s performance and extending the lifespan of major drivetrain components.
Recommended AMSOIL Products
For the 2018 LAND CRUISER equipped with the 5.7L V8, the primary requirement is a 0W-20 viscosity motor oil. The following AMSOIL products are formulated to meet or exceed the needs of this specific engine configuration:
- AMSOIL Signature Series 0W-20 100% Synthetic Motor Oil – The ultimate choice for protection against wear and horsepower loss, offering up to 25,000 miles of guaranteed protection.
- AMSOIL Extended-Life 0W-20 100% Synthetic Motor Oil – Provides extended oil change intervals up to 20,000 miles with superior cleaning power to keep the engine running smoothly.
- AMSOIL OE 0W-20 100% Synthetic Motor Oil – A cost-effective synthetic option that effectively fights sludge and deposits while protecting turbochargers.
- AMSOIL 0W-20 100% Synthetic High-Mileage Motor Oil – Specially formulated for engines with over 75,000 miles to reduce sludge and boost detergency.
- AMSOIL Oil Filter – Delivers 99 percent filtering efficiency at 20 microns and is designed for extended service life.
- WIX Oil Filter – An OEM-quality alternative that offers premium media improvements over standard factory filters.
The 2018 LAND CRUISER requires approximately 7.9 quarts of oil (with filter). When the time comes for an oil change, pairing your oil with a high-efficiency filter ensures that contaminants are captured effectively, protecting the engine’s critical components from abrasion and buildup. Beyond the crankcase, the cooling system is vital for managing the heat generated by the large displacement engine. The cooling system capacity is 17.1 quarts. For this application, you can choose between AMSOIL Passenger Car & Light Truck Antifreeze & Coolant, which is a convenient 50/50 pre-mix, or AMSOIL Propylene Glycol Antifreeze and Engine Coolant, a concentrated formula offering extended protection up to 150,000 miles or five years.
Moving to the drivetrain, the 8-speed automatic transmission (AE80F) requires a specialized fluid to handle the demands of heavy towing and shifting. The initial fill capacity is 2.9 quarts, while a total fill is 10.7 quarts. Recommended options include the AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid for superior performance under stress, or the AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid for cost-conscious owners seeking OEM-level performance.
The front and rear differentials utilize 75W-85 gear oil. The front differential holds 4 pints, and the rear holds 8.9 pints. The AMSOIL SEVERE GEAR® 75W-85 100% Synthetic Gear Lube is the ideal choice, providing advanced wear protection and controlling thermal runaway. For braking systems, the hydraulic AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid should be used to ensure consistent pedal feel and stability across a wide temperature range. To maintain peak engine performance, the AMSOIL P.i.® Performance Improver Gasoline Additive can help restore up to 14% horsepower and clean fuel injectors.
About the Vehicle
The 2018 Toyota LAND CRUISER represents the pinnacle of rugged, long-distance touring capability. Built on a robust platform designed for global adventure, this vehicle combines the reliability of a legendary Japanese brand with the sheer power of a 5.7L V8 engine. The 3UR-FE engine, a non-turbocharged powerhouse, is engineered to deliver smooth torque and dependable performance in the harshest environments, making it a favorite among overlanders and expedition travelers.
Owners of this vehicle value the LAND CRUISER for its reputation of near-indestructibility and its ability to serve as a primary mode of transport in remote areas. It is a full-size SUV that prioritizes mechanical durability over fuel economy, a trade-off that results in a vehicle capable of towing heavy loads and navigating difficult terrain with ease. The interior is spacious, designed to accommodate passengers and gear comfortably for days on the road. Its market position is unique, as it remains a traditional, body-on-frame SUV in an increasingly crossover-dominated segment.
While the vehicle is famously reliable, the high-performance nature of its engine and the stress of heavy loads can lead to specific maintenance challenges. The large V8 engine can be prone to increased oil consumption over time, especially as the vehicle accumulates high mileage. Using a high-mileage synthetic motor oil formulated with seal conditioners and enhanced detergents can help mitigate oil burn-off and reduce sludge buildup, ensuring the engine breathes better and runs cleaner. Another common issue in high-mileage examples is the development of oil leaks around the valve cover gaskets and front crankshaft seal due to thermal expansion and contraction cycles. Synthetic lubricants with superior seal conditioning properties can help swell and protect these aging seals, slowing the rate of seepage.
Furthermore, the heavy-duty nature of the LAND CRUISER means the transmission often operates under higher thermal loads than typical daily drivers, particularly when towing. This can lead to the breakdown of conventional automatic transmission fluid. Switching to a synthetic transmission fluid that resists thermal oxidation and maintains viscosity under stress can prevent shuddering and extend the life of the transmission. Finally, the transfer case, essential for its four-wheel-drive capability, experiences significant stress during low-range crawling. Using a synthetic gear lube with the right friction modifiers helps reduce wear on the chain and gears, ensuring the transfer case remains responsive and reliable for off-road excursions.
In summary, the 2018 LAND CRUISER is a vehicle that demands respect and proper care. By utilizing the correct synthetic lubricants, owners can maximize the vehicle’s legendary longevity and performance potential, ensuring it remains a trusted companion for years to come.
