What kind of oil does a Lexus GS350 take?
The Lexus GS350 typically requires a full synthetic engine oil with a viscosity of 5W-30. Always verify the exact specification for your model year and region in the owner’s manual or on the oil fill cap.
Understanding the standard recommendation
The GS350’s 3.5-liter V6 engine performs best with a high-quality synthetic oil that can withstand regular start–stop driving and spirited driving alike. The most common specification across many model years is 5W-30 full synthetic, meeting API SN or newer and ILSAC GF-5 or GF-6 standards, depending on the year.
Oil requirements can vary by year, market and even production batch. Checking the precise specification ensures compatibility with updated engine tolerances and warranty conditions.
Recommended oil specifications
Below are the typical guidelines most GS350 owners will encounter when selecting oil. This list consolidates common specs across many model years, but you should verify for your vehicle.
- Viscosity: 5W-30
- Oil type: Full synthetic oil
- Certification: API SN or newer (ILSAC GF-5 or GF-6 depending on model year)
- Oil capacity (with filter): approximately 6 quarts (5.7–6.4 qt depending on year and engine variant)
Note: Always confirm the exact specification for your year via the owner's manual, the under-hood oil cap, or a dealer, as some late-model GS350s may allow or require slightly different specs due to updated engineering or regional standards.
How to find the exact requirement for your car
Because Lexus updates recommendations over time and across markets, you should use one of these methods to confirm the exact oil specification for your GS350:
- Check the owner’s manual’s lubrication or maintenance section for the approved viscosity and API/ILSAC spec.
- Inspect the oil fill cap; many cars imprint the required viscosity on the cap.
- Look at the service sticker in the door jamb or consult a Lexus dealer or authorized service center.
Following the maker’s guidance helps ensure optimal lubrication, maintain warranty coverage, and support engine longevity.
Summary
In short, the Lexus GS350 typically takes 5W-30 full synthetic engine oil that meets API SN/ILSAC GF-5 or newer specs. Always confirm the exact specification for your model year and region via the owner’s manual or your dealer to ensure compatibility and performance.
