What kind of oil does a Lexus 350 take?

Most Lexus 350 models require 0W-20 synthetic motor oil as the standard specification; verify your exact year/model in the owner's manual or on the oil filler cap.


Understanding the question and the common baseline


The term "Lexus 350" covers several vehicles that use a 3.5-liter V6 engine (notably the RX 350, ES 350, GS 350, and LS 350). While the exact grade can differ by year and market, the modern Lexus 3.5L V6 family is typically paired with a 0W-20 viscosity oil, in most cases synthetic. This small viscosity helps with fuel efficiency and cold-start performance, and Lexus generally specifies synthetic oil for these engines.


Where variations appear


Variations arise mainly from older model years or different regional specifications. Some older ES 350 and RX 350 models or certain markets may have historically used 5W-30, especially before the widespread adoption of 0W-20. Always consult the owner's manual or the oil filler cap to confirm the required viscosity and specification for your exact car.


Common recommendations in list form


Below are the typical guidance points you’ll see in manuals and official guidance for the Lexus 350 family. Use this as a quick reference, but confirm with your exact vehicle's documentation.



  • 0W-20 synthetic motor oil is the standard recommendation for most 3.5L Lexus engines in recent years.

  • Check that the oil meets modern specification standards such as ILSAC GF-5 (and higher, e.g., GF-6) and API SN or better.

  • Use a high-quality fully synthetic oil; conventional oil is generally not advised for these engines.

  • In some older or regional variants, 5W-30 may have been specified; verify for your model/year.


Concluding: The list captures the typical oil grade approach, but there is variation by year, model, and market, so official documentation should always be consulted.


How to verify the exact oil requirement for your vehicle


To confirm the right oil for your exact Lexus 350, follow these steps:



  • Check the owner's manual for the "Oil viscosity" specification.

  • Inspect the oil cap on the engine for the viscosity marking (often 0W-20).

  • Look up your model/year on Lexus/Toyota technical information sites or contact a Lexus service advisor.

  • Ensure the oil you buy meets the specified API/ILSAC rating and is fully synthetic if required.


Concluding: By confirming the exact specification for your model, you ensure proper lubrication, performance, and warranty compliance.


Summary


In most modern Lexus 350 models using a 3.5-liter V6, the typical oil choice is 0W-20 synthetic. Always verify with your specific model year and market—consult the owner's manual, the oil cap, or a dealership to confirm the exact viscosity and certification required. Using the correct oil supports engine efficiency, protection, and longevity.
