Toyota dont produce oil they purchase from another producer and distribute under toyota trademark
This is what chatgpt says
Yes, Toyota does produce motor oil, but it's typically branded as Toyota Genuine Motor Oil (TGMO). This oil is specifically formulated to meet the requirements of Toyota engines. It's often manufactured in partnership with major oil companies (like ExxonMobil or others, depending on the region), but it's tested and approved by Toyota to ensure optimal performance and protection for their vehicles.
You can usually find TGMO at Toyota dealerships or authorized service centers. It comes in various grades like 0W-20, 5W-30, etc., depending on the engine specifications of your Toyota model.
