What type of oil does a Lexus GS 350 use?

The Lexus GS 350 uses 0W-20 full-synthetic engine oil.


Recommended oil type


Understanding the exact specification helps ensure proper protection and efficiency. Here are the core requirements commonly provided by Lexus and Toyota manuals.



  • Viscosity: 0W-20

  • Type: Full-synthetic engine oil

  • Specifications: API SN (or higher) and ILSAC GF-5 (GF-6 compatible oils are acceptable for newer inventories)

  • Capacity (with filter): about 6.4 quarts (6.0 liters)

  • Change interval: typically up to 10,000 miles (16,000 km) or 12 months, whichever comes first, depending on driving conditions and the vehicle’s maintenance minder


Always use OEM-recommended oil and have a professional confirm if you drive in extreme conditions or in climates that stress the engine more than typical daily driving.


Oil capacity and service intervals


Knowing how much oil the GS 350 holds and when to change it helps prevent service surprises and keeps the engine protected over time.



  • Oil capacity: about 6.4 quarts (6.0 liters) with the oil filter

  • Recommended service interval: follow the vehicle’s maintenance minder; with synthetic oil, many GS 350 owners see intervals around 10,000 miles (16,000 km), subject to driving conditions

  • Filter replacement: replace the oil filter at each oil change


Adhering to the maintenance minder and dealership guidance ensures you stay within warranty and preserve engine longevity.


Regional and model-year considerations


For most 2013–2020 GS 350 models sold in North America and many other regions, Lexus specifies 0W-20 full synthetic oil. Always verify the exact specification for your vehicle’s year and market in the owner’s manual or with a Lexus dealer, since regional climate and emissions standards can influence the recommended viscosity and oil specification.


Practical maintenance tips


To keep your GS 350 running smoothly, consider these practical notes when selecting and maintaining oil:



  • Choose a 0W-20 full-synthetic oil that meets API SN (or higher) and ILSAC GF-5/GF-6 standards

  • Opt for a reputable brand or Lexus Genuine oil, and use a new oil filter at each change

  • Ensure the oil fill is level with the recommended capacity and avoid overfilling

  • Refer to the maintenance minder for interval guidance and adjust for severe driving conditions if needed

  • When in doubt, consult a Lexus service center to confirm the correct viscosity and specification for your exact model year and region


Proper oil selection and timely changes help protect the 3.5L V6 and sustain performance.


Summary


In short, the Lexus GS 350 typically requires 0W-20 full-synthetic engine oil, with an oil capacity of about 6.4 quarts (including the filter). Most models use maintenance minder-guided intervals, commonly up to 10,000 miles or 12 months, whichever comes first. Always verify the exact specification for your vehicle’s year and market in the owner’s manual or with a Lexus dealer, and choose a high-quality oil that meets API SN/ILSAC GF-5 (or GF-6) standards.

What kind of oil does a Lexus 350 take?


The recommended oil for a Lexus 350 is typically 0W-20 full synthetic for newer models, while older models may require 5W-30 conventional oil. Always confirm the correct type and grade for your specific model and year by checking the owner's manual or the oil cap under the hood. 
Newer models (approximately 2010 and newer)

  • Type: 0W-20 full synthetic 
  • Note: Some manufacturers like Toyota, the parent company of Lexus, recommend their own 0W-20 synthetic oil. 
  • Availability: This is a common recommendation for modern, high-efficiency engines, say AutoZone and Advance Auto Parts. 

Older models (approximately 2009 and older)
  • Type: 5W-30 conventional or synthetic 
  • Note: You can find this recommendation on the oil cap of older models, say YouTube and Reddit users. 

Important considerations
  • Check your manual: The most accurate information for your specific vehicle can always be found in the owner's manual. 
  • Check the oil cap: The recommended oil grade is also printed on the oil filler cap on top of your engine, notes Reddit users. 
  • Service intervals: For newer models using 0W-20, the service interval is often 10,000 miles or 12 months. If your vehicle uses conventional (non-synthetic) oil, a more frequent change interval of 5,000 miles is advisable. 



What kind of oil does a Lexus GS 350 take?


A Lexus GS 350 typically requires 0W-20 full synthetic oil for optimal performance and fuel efficiency, though older models may have used 5W-30. Always confirm the exact oil type and capacity for your specific model year by checking the owner's manual or the oil filler cap. 
Recommended oil

  • Viscosity: 0W-20 is the modern, standard recommendation, especially for newer models, to help with fuel economy and cold starts. Some older models may specify 5W-30 as an acceptable alternative or primary choice. 
  • Type: Full synthetic oil is the factory-recommended type to ensure proper lubrication and protection. 

Capacity
  • Rear-wheel drive (RWD): Approximately 6.6 quarts (6.3 liters) with filter change. 
  • All-wheel drive (AWD): Approximately 6.8 quarts (6.4 liters) with filter change. 
  • Note: These capacities can vary slightly, so always double-check your owner's manual and confirm the oil level after refilling. 

Important considerations
  • Check the manual: The most accurate information for your specific vehicle will always be in the owner's manual or on the oil filler cap. 
  • Oil filter: Be sure to replace the oil filter with every oil change. 
  • Brand vs. type: While brands like Mobil 1 or AMSOIL are popular, the most important factor is using the correct oil type and viscosity (0W-20 or 5W-30) that meets Lexus's specifications.
