This article explains the official oil capacity for the NX300, the recommended oil type, and practical guidance to ensure you maintain the correct oil level between changes.
Official oil capacity and specifications for the 2021 NX300
Understanding the exact capacity helps with proper maintenance and avoiding overfill or underfill. The NX300’s turbocharged 2.0-liter engine is designed to run on synthetic oil, and the capacity figure commonly cited by Lexus service documentation includes the filter change.
The following key specifics summarize what you need to know when servicing the NX300’s engine oil:
- Engine oil capacity (including filter): approximately 5.5 quarts (about 5.2 liters).
- Recommended oil viscosity: 0W-20 synthetic oil for most climates and driving conditions.
- Oil specification: should meet Lexus/Toyota standards and, where possible, ILSAC GF-6 (or newer) specification as advised by the owner’s manual or service information.
For the most accurate figure, always verify in the owner’s manual or on the engine oil fill cap, since capacity can vary slightly by market, engine variant, or when a different filter is used.
Maintenance considerations
Keeping the correct oil level is essential for engine protection and performance. Always use the recommended synthetic oil and check the level after a change with the vehicle’s monitoring system or dipstick (if equipped). If you’re unsure about the exact capacity for your specific NX300 model year or regional specification, consult the owner’s manual or contact a Lexus service center.
Additional notes
If you replace only the oil and not the filter, capacity figures may differ slightly from the full-change specification. Always record the exact quantity you added and recheck the level after the engine has circulated the new oil.
Summary
The 2021 Lexus NX300 typically requires about 5.5 quarts (5.2 liters) of engine oil when performing a full change with a filter, using synthetic 0W-20 oil. Verify the exact capacity against your owner’s manual or the fill cap label, and follow Lexus’ maintenance schedule for optimal engine health.
