What kind of oil does a Lexus GS350 use?
Most Lexus GS 350 models use synthetic 5W-30 engine oil. In some markets or model years, 0W-20 may be specified. Always confirm the exact requirement from your owner's manual or by checking the oil filler cap on the engine.
Oil requirements by year and region
The GS 350's engine (the 2GR-FSE 3.5L V6) generally runs on synthetic motor oil, but the exact viscosity can vary depending on year, climate, and regional specifications. The guidance below reflects common baselines and should be verified for your VIN.
- Typical baseline: Synthetic 5W-30, meeting API SN+/ILSAC GF-6 or newer, suitable for most GS 350 models in many regions.
- Possible alternative: Synthetic 0W-20 in certain markets or model years where Lexus specifies this viscosity for fuel economy or cold-start performance. Always verify with the manual or dealer.
- General rule for all cases: Use a high-quality full-synthetic oil from a reputable brand and avoid conventional oil unless explicitly allowed in the manual.
Conclusion: The safest approach is to follow the exact specification listed for your car’s year and market. If in doubt, contact a Lexus service professional or consult the owner’s manual for your VIN.
How to confirm the exact specification for your GS350
To ensure you’re using the correct oil for your specific vehicle, use these verification steps.
- Check the owner's manual: Look in the specifications section for the recommended viscosity and API/ILSAC ratings.
- Inspect the oil filler cap: Some engines print the recommended viscosity on the cap itself.
- Refer to VIN-specific data: Use Lexus/Toyota service information or dealership resources tied to your VIN to confirm the exact spec.
- Ask a Lexus dealer or qualified technician if you’re unsure about your market-year configuration.
Conclusion: Verifying through official manuals or a dealer helps avoid using an incorrect grade, especially if you live in extreme climates or have a unique model year.
Oil certifications and why they matter
Modern engine oils carry certifications that indicate performance standards. For the GS350, oils that meet API SP (or SN/SL as applicable) and ILSAC GF-6 (or GF-5) are commonly acceptable. These standards cover protection against wear, sludge, and deposit formation, as well as fuel economy considerations.
API SN/SP and ILSAC GF-6 explained
API SN and SP are performance categories from the American Petroleum Institute, with SP being the newer standard that improves high-temperature deposit protection and engine cleanliness. ILSAC GF-6 (and GF-5) are parallel performance specs used in North America and elsewhere to ensure compatibility with modern engines and fuel economy targets. When selecting oil, ensure the label shows SN/SP and GF-6 or GF-5 as appropriate for your vehicle’s year and region.
Summary
In short, the Lexus GS 350 typically requires a synthetic oil, most commonly 5W-30, with some markets or years permitting 0W-20. Always verify the exact viscosity and certification requirements for your specific car using the owner's manual, the oil cap, or a Lexus dealer based on your VIN. Use a high-quality synthetic oil that meets API SN/SP and ILSAC GF-6 or newer to protect the engine and maintain performance.

What oil does a Lexus GS 350 take?
A Lexus GS 350 typically takes SAE 0W-20 full synthetic oil, though older models might use different viscosity. Always check your specific owner's manual, as newer models like the 2020 model recommend 0W-20 synthetic, while some older models might have been designed for other viscosities like 5W-30.
| Model Year Range | Recommended Oil Viscosity |
|---|---|
| 2013-2020 (3.5L V6) | 0W-20 synthetic |
| 2007-2011 (3.5L V6) | 5W-30 (check owner's manual) |

Important considerations
- Always check your owner's manual: Your car's manual is the most accurate source of information for your specific model and year. It will list the exact oil viscosity and capacity needed.
- Use full synthetic: Lexus recommends premium-grade synthetic oil for optimal performance and engine protection, especially for newer models.
- Capacity varies: The amount of oil needed depends on whether the model is rear-wheel drive (RWD) or all-wheel drive (AWD).
- Replace the filter: Always replace the oil filter when you change the oil to avoid contamination.
- Consider high mileage oil: If your GS 350 has high mileage, some manufacturers suggest using a high-mileage oil formula to help reduce oil consumption and potential leaks.
