Engine Oil

The 2023 RAV4, equipped with the A25A-FKS 2.5L 4-cylinder engine, is designed to use SAE 0W-16 viscosity grade engine oil. This is a low-viscosity oil designed for maximum efficiency and fuel economy. Using a thicker oil like 5W-20 or 5W-30 can lead to reduced fuel economy and may affect the performance of the variable valve timing (VVT) system.

• Specification: Toyota specifies an oil that meets API SP and ILSAC GF-6B standards. Always look for the API "donut" and ILSAC "starburst" symbols on the bottle to ensure you are using a certified product.
• Capacity: With a filter change, the engine requires 4.8 quarts (4.5 liters). Without a filter change, it is 4.4 quarts (4.2 liters). It is always recommended to change the filter with every oil change.
• Interval: Toyota recommends a standard oil change interval of 10,000 miles or 12 months, whichever comes first, under normal operating conditions. However, if you frequently drive in harsh conditions (e.g., extensive idling, dusty roads, towing, or short trips in cold weather), the interval should be shortened to 5,000 miles or 6 months.
• Note for Hybrid: The RAV4 Hybrid uses the same A25A-FXS engine and requires the same SAE 0W-16 oil and specifications.

Engine Coolant

Toyota vehicles use a specific pink-colored, ethylene-glycol based coolant that is critical for the health of the cooling system and hybrid components.

• Specification: Use only Toyota Genuine Super Long Life Antifreeze/Coolant. This is a pre-diluted 50/50 mixture, so do not add water. It is a Phosphate-enhanced Organic Acid Technology (P-OAT) coolant.
• Pitfall: Never mix this pink coolant with other colors or types, such as standard green IAT (Inorganic Acid Technology) or orange DEX-COOL (OAT). Mixing coolants can cause them to gel, leading to blockages in the radiator, heater core, and engine, which can result in catastrophic overheating and damage.
• Capacity: The total system capacity varies depending on the model and powertrain. It ranges from approximately 6.5 quarts for gasoline models to 8.9 quarts for hybrid models, which have additional cooling loops for their inverter and hybrid battery systems. Verify the exact capacity in your owner's manual.
• Interval: The factory fill is designed to last for 10 years or 100,000 miles. Subsequent changes are recommended every 5 years or 50,000 miles.

Transmission Fluid

The 2023 RAV4 uses a sealed automatic transmission. There is no dipstick for the owner to check the fluid level or condition. This is a growing trend in the automotive industry to reduce maintenance errors and ensure the use of the correct fluid.

• Specification: The transmission requires Toyota Genuine ATF WS (World Standard) fluid. Do not use any other type of ATF, including universal or multi-vehicle fluids. Use of a non-specified fluid can cause harsh shifting, transmission shudder, and eventual failure.
• Service: While often called "lifetime" fluid, it is not. The definition of "lifetime" is the intended service life of the vehicle, not indefinite. Most technicians recommend a drain-and-fill service between 60,000 and 100,000 miles to promote longevity, especially if the vehicle is used for towing or driven in mountainous terrain. Service should be performed by a qualified technician who can correctly check the fluid level at a specific temperature using the overflow plug.

Transfer Case & Rear Differential (AWD Models)

AWD models have a power transfer unit (transfer case) and a rear differential that require periodic gear oil changes.

• Specification: Both the transfer case and rear differential require Toyota Genuine Gear Oil SAE 75W-85 API GL-5.
• Capacities:
  • Transfer Case: Approximately 0.4 quarts.
  • Rear Differential: Approximately 0.5 quarts.
• Interval: While not always listed on the standard maintenance schedule, it is wise to replace this fluid every 30,000 to 60,000 miles to remove metal shavings and prevent wear. The fluid level should be inspected if any leaks are suspected.

Brake Fluid

The brake system requires high-quality fluid to operate safely under all conditions.

• Specification: Use DOT 3 or DOT 4 brake fluid from a sealed container. DOT 4 has a higher boiling point, which can be beneficial in mountainous regions or for spirited driving, but DOT 3 is perfectly adequate for most users. The RAV4 Hybrid's electronically controlled braking system also uses this fluid.
• Common Pitfall: Brake fluid is hygroscopic, meaning it absorbs moisture from the air over time. This moisture lowers the boiling point, which can lead to a spongy pedal or complete brake failure in hard-braking situations. It also causes internal corrosion of brake lines and components.
• Interval: Replace the brake fluid every 2-3 years or 30,000 miles, regardless of mileage, to flush out moisture and contaminants.

Power Steering Fluid

The 2023 Toyota RAV4 is equipped with an Electric Power Steering (EPS) system. This system uses an electric motor to provide steering assistance instead of a hydraulic pump and fluid. Therefore, there is no power steering fluid to check or change.

Windshield Washer Fluid

While seemingly simple, using the correct washer fluid for your climate is important for visibility and safety.

• Specification: Use a quality commercial washer fluid. In climates where temperatures fall below freezing, use a winter-blend fluid with a low freezing point to prevent the reservoir and lines from freezing and cracking.
• Capacity: The reservoir holds approximately 4.8 quarts (4.5 liters).
