What oil does a 1UZ take?

The 1UZ-FE engine, commonly found in Toyota Lexus models, requires a specific type of engine oil. The recommended oil for a 1UZ engine is typically a high-quality synthetic 5W-30 or 5W-40 motor oil.


Detailed Overview of the 1UZ Engine Oil Requirements


The 1UZ-FE is a 4.0-liter V8 engine produced by Toyota and used in various Lexus and Toyota models from 1989 to 2002. This engine is known for its reliability and performance, but it does have specific oil requirements that should be followed to ensure optimal engine health and longevity.



  • Oil Type: The 1UZ-FE engine is designed to use a high-quality synthetic 5W-30 or 5W-40 motor oil. These oil viscosities provide the necessary lubrication and protection for the engine's components, even in extreme operating conditions.

  • Oil Capacity: The 1UZ-FE engine has an oil capacity of approximately 5.1 quarts (4.8 liters) for a full oil change.

  • Oil Change Interval: Toyota recommends changing the engine oil and filter every 5,000 to 10,000 miles (8,000 to 16,000 km) or every 6 to 12 months, whichever comes first.

  • Oil Specifications: The 1UZ-FE engine requires an oil that meets or exceeds the API (American Petroleum Institute) service rating of SJ or higher. Some automakers may also recommend oils that meet ILSAC (International Lubricant Standardization and Approval Committee) GF-3 or GF-4 specifications.


It's important to follow the manufacturer's recommendations for the 1UZ-FE engine to ensure optimal performance and longevity. Using the wrong oil type or failing to change the oil at the recommended intervals can lead to increased wear, reduced fuel efficiency, and even engine damage over time.

For 5w40 oil:
In practice, this means that each oil is just as viscous at lower temperatures and will remain viscous at -30°C, however 5w40 oil outperforms 5w30 oils at higher temperatures, being effective up to ambient temperatures of 50°C, as opposed to 30°C.

Is 10w40 thicker than 5W30?


In other words, a lubricant with SAE 5W-30 will behave better when cold than a lubricant with SAE 10W-40. In contrast, oils with a higher SAE after the W generate thicker films of lubricant and better protect the mechanical parts when the vehicle is already hot.
