How much oil does a Lexus is350 take?
The IS350 typically requires about 6.0 quarts (5.7 liters) of engine oil for a full change with the filter. Always verify the exact amount for your year and trim in the owner's manual and by checking the dipstick after filling.
Oil capacity: what to expect
The IS350 uses a 3.5L V6 (2GR-FSE) and generally calls for roughly six quarts of oil during a full change that includes the oil filter. Exact capacity can vary slightly by model year, oil filter type, and whether the filter is replaced. If you drain only and reuse the same filter setup, you might need around 5.5–5.7 quarts. Always consult the owner's manual for your specific vehicle and confirm the level with the dipstick after filling.
Typical figures by generation/year
Here are representative figures for common IS350 configurations. Exact values may vary by market and equipment, so treat these as guidelines and verify against official documentation for your VIN.
- IS350 (2006–2013) with 3.5L V6: about 6.0 quarts (5.7 L) with filter; approximately 5.5–5.7 quarts without the filter.
- IS350 (2014–2019) continuing the 2GR-FSE setup: about 6.0 quarts (5.7 L) with filter; similar tolerance.
In practice, most owners fill to the full line on the dipstick after a complete oil change and filter replacement, then re-check once the engine has run and cooled as recommended.
What oil and how to fill correctly
The typical recommendation is a synthetic 5W-30 oil for the IS350 in most regions, though some climates or markets may permit other grades per Lexus guidelines. Use the correct Lexus/TOYOTA oil filter and ensure the drain plug gasket is replaced if needed. Begin with about 5.5–6.0 quarts, then top up as necessary after checking the dipstick and engine temperature.
Step-by-step quick guide
- Park on level ground and let the engine cool before you start draining oil.
- Drain old oil, replace the oil filter, and inspect the drain plug gasket; reinstall securely.
- Pour in about 5.5–6.0 quarts of oil to start, depending on whether you are replacing the filter.
- Run the engine for a minute, turn it off, wait a few minutes, then check the oil level on the dipstick and add in small increments until it reaches the full mark.
Always rely on the dipstick for final verification, and consult your owner's manual or a Lexus technician for the exact specification for your VIN and region.
Why accuracy matters
Using the correct oil capacity and grade helps protect the 3.5L V6 from wear and maintain performance. Underfilling can cause insufficient lubrication, while overfilling can create excess pressure and foaming.
Summary
For most Lexus IS350 models, the engine oil capacity is about 6.0 quarts (5.7 liters) with the filter. Expect slight year-to-year variation and regional guidelines; always verify with the owner's manual and your dipstick. Use the recommended synthetic 5W-30 oil and a compatible filter, and consult a Lexus technician if you’re unsure about your specific VIN.
