What kind of oil does a Toyota Highlander V6 take?

Most Highlander V6 engines require 0W-20 synthetic oil. Verify the exact grade for your model year in the owner’s manual or on the under-hood oil label, since specifications can vary by year and market.


This article surveys the typical oil requirements for common Highlander V6 configurations, explains how to confirm the right oil for your vehicle, and offers maintenance tips to keep the engine running smoothly.


Typical oil specification for Highlander V6


Before listing the usual guidance, note that the majority of modern Highlander V6s use a lightweight, fully synthetic oil. The following points summarize what you’re likely to encounter across generations.


Common oil grade and related specs you’ll encounter:



  • Viscosity: 0W-20

  • Oil type: Full synthetic preferred; synthetic blends may be acceptable if explicitly approved in your manual

  • Standards: API SP (or newer) and ILSAC GF-6A (or newer); Toyota Genuine Motor Oil often recommended

  • Usage note: Always align with the exact specification printed in your manual or on the engine bay sticker


In short, for the vast majority of Highlander V6 models sold in recent years, 0W-20 synthetic is the standard choice. Always confirm for your specific year and market to avoid mismatches.


Oil requirements by generation (illustrative guidance)


To help readers navigate, the following sections outline broad guidance across generations. Always rely on your vehicle’s official documentation for a definitive answer.


Older Highlander V6 generations


Earlier Highlander V6 models often varied by year and market. While some used conventional or heavier viscosities, many of these engines can still be compatible with 0W-20 synthetic if confirmed by the manual or dealer. If you own a legacy Highlander, check the exact specification label under the hood or the owner’s manual.


Recent and current Highlander V6 generations


In most late-model Highlander V6s, the recommended oil is 0W-20 synthetic. This aligns with Toyota’s current practice for many of their V6 and other gasoline engines, supporting good fuel economy and cold-start performance while protecting engine internals.


How to verify your specific Highlander V6 oil requirement


To be certain you’re using the correct oil, follow these steps:



  1. Consult the owner’s manual for the exact viscosity and specification (for example, 0W-20 with API SP and GF-6A).

  2. Check the under-hood label near the engine or on the cap for the recommended grade and spec.

  3. If the manual is unavailable, contact a Toyota dealer or a qualified mechanic with your VIN to confirm the correct oil.


Following these steps ensures you use the precise oil formulation your Highlander V6 requires, protecting warranty coverage and engine longevity.


Maintenance and oil-change intervals


Maintenance intervals depend on driving conditions and the oil you use. With synthetic oil, Toyota’s Maintenance Minder and your owner’s manual will guide you toward longer intervals, often up to 7,500–10,000 miles (12,000–16,000 km) under normal conditions, but severe driving or towing may require more frequent changes.


Always adhere to the Maintenance Minder recommendations and reset or record oil changes accordingly to keep your Highlander’s engine performance optimal.


Summary


For most Toyota Highlander V6 models, 0W-20 synthetic oil is the recommended standard. Always confirm the exact grade and spec for your vehicle year and market by checking the owner’s manual or the engine bay sticker, and follow the maintenance minder guidance for oil-change intervals. When in doubt, consult a Toyota dealer or a qualified mechanic to ensure you’re using the correct oil for your Highlander V6.
