2022 Toyota Highlander Fluid Type Specs

Quick reference

Engine Oil

For the 2022 Toyota Highlander, the manufacturer specifies 0W-20 synthetic engine oil. It is crucial to use oil that meets or exceeds API SN Plus or API SP standards. These newer API standards address issues like low-speed pre-ignition (LSPI) in turbocharged gasoline direct injection engines, which are common in modern vehicles like the Highlander. Using an oil that doesn't meet these specifications can lead to engine damage and reduced fuel efficiency.

Capacity: The oil capacity generally ranges from 4.8 to 5.3 quarts (4.5-5.0 liters), including the filter. However, this can vary slightly depending on the specific engine (e.g., 2.5L Hybrid, 3.5L V6) and drivetrain configuration. Always verify the exact capacity in your owner's manual or OEM service information.

Intervals: Toyota typically recommends engine oil changes every 10,000 miles or 12 months, whichever comes first, for normal driving conditions with synthetic oil. However, if you frequently drive under severe conditions (e.g., towing, extreme temperatures, dusty environments, extensive idling), more frequent changes, such as every 5,000 miles or 6 months, are advised. Always consult your owner's manual for the most accurate service schedule for your specific Highlander.

Common Pitfalls: Never use an oil that does not meet the specified viscosity (0W-20) and API rating. Using a heavier weight oil can increase friction, reduce fuel economy, and potentially lead to lubrication issues. Ensure the oil you use is genuine and from a reputable brand to avoid counterfeit products.

Engine Coolant

The 2022 Toyota Highlander requires Toyota Super Long Life Coolant (SLLC). This is a pre-mixed 50/50 ethylene glycol-based, pink/red-colored, phosphate hybrid organic acid technology (P-HOAT) coolant. It meets Toyota's stringent specifications for corrosion protection and longevity.

Capacity: The coolant capacity typically ranges from 7.9 to 8.4 quarts (7.5-7.9 liters), depending on the engine and trim level. Always refer to your owner's manual for the precise capacity.

Intervals: Toyota SLLC is designed for extended service intervals, often recommending replacement every 100,000 miles or 10 years for the first change, and then every 50,000 miles or 5 years thereafter. Regular inspection of coolant levels and condition is still recommended during routine service.

Common Pitfalls: Never mix Toyota SLLC with other types of coolant, especially conventional green or yellow coolants, or coolants designed for different technologies (e.g., pure OAT or HOAT without phosphates). Mixing coolants can lead to chemical incompatibilities, gelling, corrosion, and severe damage to the cooling system and engine. Always use genuine Toyota SLLC or an equivalent that explicitly states compatibility with Toyota's P-HOAT specification.

Transmission Fluid

The 2022 Toyota Highlander utilizes Toyota WS (World Standard) automatic transmission fluid. This is a highly specialized, low-viscosity synthetic fluid designed for Toyota's modern automatic transmissions. It is formulated to provide optimal shift quality, wear protection, and fuel efficiency.

Capacity: The transmission in the Highlander is considered a
