What viscosity is Toyota genuine motor oil?
Toyota Genuine Motor Oil comes in several viscosity grades, not a single specification. The most common choices for modern Toyotas are 0W-20 and 5W-30, with 0W-16 and 5W-20 also offered for certain engines and regional markets.
Which grade you should use depends on your vehicle’s engine, climate, and the specification printed in your owner's manual. Always follow Toyota's recommendations for your specific model.
Viscosity grades offered by Toyota Genuine Motor Oil
The following are the main viscosity grades you may encounter when shopping for Toyota Genuine Motor Oil.
- 0W-20: The standard grade for many newer Toyota engines. Supports fuel efficiency and reliable cold-start performance, and is commonly sold as synthetic.
- 5W-30: Used in some engines and markets, particularly where higher-temperature protection or legacy engine needs apply. Often synthetic in TGMO lines.
- 0W-16: A very low-viscosity option available for select newer models and markets to maximize efficiency. Not all engines require or approve 0W-16; check the manual.
- 5W-20: Available for certain engines and regions where this grade is specified. Suitable for specific equipment and climate conditions as designated by Toyota.
Availability of these grades varies by region, model year, and engine specification. Always verify the correct viscosity with your owner’s manual or a Toyota dealer to ensure compatibility.
Why viscosity choice matters
Using the recommended viscosity is important for protecting engine components, maintaining proper oil flow, and achieving intended fuel efficiency. An incorrect grade can affect lubrication reliability, cold-start performance, and overall engine longevity. Always follow the official Toyota specification for your vehicle.
Summary
Toyota Genuine Motor Oil is not one universal viscosity. The brand offers multiple grades—most notably 0W-20 and 5W-30, with 0W-16 and 5W-20 available in certain markets or engines. To determine the right grade for your Toyota, consult your owner's manual or ask a Toyota dealer or service professional. Choosing the correct viscosity helps protect the engine and sustain performance over time.
