Who makes engine oil for Lexus?
Lexus uses Toyota Genuine Motor Oil (TGMO) as the factory-recommended engine oil; the oil is produced under contract by refiners around the world to Toyota's specifications, so there isn't a single company that makes all Lexus engine oil.
What is Toyota Genuine Motor Oil?
Toyota Genuine Motor Oil is the official lubricant line designed to meet Toyota and Lexus engine requirements. It covers synthetic and conventional grades and is sold at Toyota and Lexus dealerships as well as authorized retailers. The precise refinery that produces TGMO can vary by region and year, but the oil is formulated to Toyota specifications regardless of the producer. Toyota continues to maintain TGMO across its lineup and relies on contract refiners to produce TGMO; this supply approach remains in effect in 2025.
Variants and grades
Common viscosity grades used across Lexus engines include 0W-20 for many newer engines, with 5W-30 also used for certain variants. The exact grade depends on the engine, climate, and model year.
- 0W-20 full synthetic is a typical recommendation for many recent Lexus/Toyota engines.
- 5W-30 is used in some engines and older models, or in specific climates.
- Oil specifications may align with API GF-6 or API SN/RN for newer engines, depending on age and region.
Understanding these options helps ensure proper lubrication and performance. For definitive guidance, consult your owner's manual or a Lexus service advisor.
Who makes it?
The exact maker varies by market. Toyota contracts multiple refiners to produce TGMO to its specifications, so the company behind the oil can differ depending on the country or region. The branding remains consistent as Toyota Genuine Motor Oil or Lexus service oil to ensure compatibility with Toyota/Lexus engines.
- Regional contract manufacturers: Refineries in different regions produce TGMO under license to Toyota, ensuring supply for local dealers and service centers.
- Branding and compliance: The oil carries Toyota/Lexus branding and is formulated to meet Toyota's performance and emission standards.
- Supply chain flexibility: The arrangement allows Toyota to source oil from multiple partners to match demand and local regulations.
- Aftermarket options: In some markets, high-quality oils that meet the same Toyota specs may be offered by independent brands, though Toyota recommends TGMO for factory fills.
In short, the identity of the exact company making the oil varies, but every batch is produced to Toyota's specification and branded accordingly for Lexus customers.
How to ensure you’re using the right oil
Using the correct oil is essential for performance and warranty coverage. Here are steps to follow:
- Check the owner's manual for the recommended viscosity grade (for example, 0W-20 or 5W-30) and API specification for your specific model.
- Look at the oil fill cap or the underside of the engine cover for the recommended grade and specification.
- Use Toyota Genuine Motor Oil or an equivalent oil that meets the Toyota specification and API rating required by your engine, especially if you are unable to obtain TGMO.
- Consult a Lexus dealer or trusted service provider if you are unsure which oil to use or if your vehicle has special requirements (hybrids, turbocharged engines, etc.).
Staying aligned with the official recommendations helps protect the engine and maintain warranty coverage.
Summary
In summary, Lexus engine oil is Toyota Genuine Motor Oil, produced by multiple contract refiners under Toyota’s specifications. The exact producer can vary by region, but the product remains branded and spec’d for Lexus engines. Always verify the correct viscosity and API specification in the owner's manual or with a dealer, and choose TGMO or an equivalent that meets Toyota’s requirements.
