How many quarts does a Lexus is350 take?
The Lexus IS350 typically takes about 6 quarts of engine oil with a new filter during a full oil change, roughly 5.7 liters. Exact capacity can vary slightly by model year and engine variant, so always confirm in the owner’s manual.
Oil capacity by configuration
Understanding the standard oil capacity helps ensure you fill to the correct level. The figures below reflect common IS350 configurations and note when a filter change is included.
- Oil capacity with filter: 6.0 quarts (5.7 liters).
- Oil capacity without filter: approximately 5.0 quarts (4.8 liters).
These values are typical for the 3.5-liter V6 used in most IS350 models. Variations can occur by year, engine revision, or regional specifications, so verify against your VIN-specific manual or service guide.
What affects the capacity?
While the standard figure is around 6.0 quarts with a filter, several factors can influence the exact amount you need. Engine revisions, changes in oil filter design, and differences in oil flow or cooling accessories can cause small variations. Always consult the precise capacity listed for your exact vehicle configuration.
Practical steps for an oil change
When performing an oil change, following a clear, methodical process helps ensure you use the correct total capacity and avoid overfilling.
- Prepare the correct oil type and a new oil filter recommended for your IS350, and have a suitable drain container ready.
- Warm the engine briefly, then turn it off and lift the car safely if you need to access the drain plug.
- Place a drain pan under the oil pan, remove the drain plug, and allow the old oil to drain completely.
- Remove and replace the oil filter, ensuring a light coat of oil on the gasket for a proper seal.
- Reinstall the drain plug, then slowly refill with the recommended amount of oil (roughly 6.0 quarts with filter) while checking the level with the dipstick.
- Run the engine for a few minutes, check for leaks, and recheck the oil level after the engine has cooled or rested.
Following these steps helps ensure you reach the correct full level and avoid overfilling, which can affect engine performance and emissions systems.
Summary
The Lexus IS350 generally requires about 6 quarts (5.7 liters) of engine oil when performing a full change with a new filter. Always verify the exact capacity for your specific model year and engine variant in the owner's manual or service guide, and follow the manufacturer’s recommended oil grade. Properly checking and refilling ensures optimal lubrication and engine longevity.
