How much oil does a GS 350 take?
The GS 350 typically uses about 6.4 quarts (roughly 6.1 liters) of engine oil for a full oil change with a new filter.
The Lexus GS 350, a mid-size luxury sedan, relies on a 3.5-liter V6 engine that has seen a couple of technical updates across model years. Oil capacity can vary slightly depending on the specific engine variant (for example, older 2GR-FE variants versus newer 2GR-FKS variants) and whether the service includes replacing the oil filter. While 6.4 quarts is the commonly cited figure for most modern GS 350s, always confirm with the owner's manual or a Lexus service bulletin for your exact year and market.
Oil capacity by generation and year
Before listing typical capacities, note that the exact amount can differ by engine variant (older 2GR-FE vs newer 2GR-FKS) and by whether the car is a U.S. or international market model.
- GS 350 with 2GR-FFE/FE (older generation, roughly 2006–2011 in some markets) typically uses about 6.0–6.4 quarts with filter; 6.0 quarts without filter.
- GS 350 with 2GR-FKS (more recent generations, 2013–2020 in many markets) lists around 6.4 quarts with filter; about 5.9–6.0 quarts without filter.
- Some variations in the service manual specify 6.4 quarts (6.0 L) including a replaceable filter, with a bit less if the filter isn’t changed.
Conclusion: For most GS 350s, plan for about 6.4 quarts of oil when performing a standard full-synthetic oil change with a new filter. If you’re not changing the filter, you’ll typically drain about 5.9–6.0 quarts of oil. Always verify with the owner’s manual or the engine’s dipstick after a change.
What oil viscosity and type should you use?
Standard Lexus recommendations for the GS 350 generally call for synthetic oil with a viscosity appropriate to the climate and model year—commonly 0W-20 in many markets, though some versions may specify 5W-30. Use the grade specified in your owner’s manual and ensure you select an API/ILSAC certification appropriate for modern engines. If you’re in a hot or cold climate, follow the manufacturer’s guidance and consider a reputable synthetic brand.
Steps to verify oil capacity for your car
To confirm the exact capacity for your specific vehicle, you can: check the owner's manual, consult the service/maintenance section of the Lexus customer portal, or speak with a Lexus-certified technician. Also, the oil change procedure typically includes draining the old oil, replacing the filter, and topping up to the recommended level via the dipstick.
Why this matters
Understanding the exact oil capacity helps avoid overfilling or underfilling, which can affect engine protection, performance, and emissions. Overfilling can cause foaming and crankcase pressure, while underfilling can reduce lubrication and increase wear over time. Following a precise capacity ensures the engine remains properly lubricated after every service.
Summary
For the Lexus GS 350, plan on about 6.4 quarts (roughly 6.1 liters) of engine oil when doing a standard oil change with a new filter. If you do not replace the filter, you’ll typically end up with about 5.9–6.0 quarts. Always confirm with your vehicle’s manual for your exact model year and engine variant, and verify the correct viscosity and specification before changing the oil.
