How much oil does a Lexus nx300h take?
The Lexus NX300h takes about 4.5 quarts (4.3 liters) of engine oil for a standard oil change, including the filter, when using a full-synthetic 0W-20 oil. Always verify the exact figure in your owner's manual or with a Lexus dealer for your year and market.
Context and year-to-year variations
The NX300h uses a 2.5-liter Atkinson-cycle engine paired with an electric motor, and while the general capacity is consistent, there can be minor variations by model year or market. The figures below reflect typical factory specifications and standard maintenance practice across recent models. Always check the manual for your specific year.
Official capacity and oil type
Below is the standard capacity and recommended oil type for most NX300h models. Note that exact numbers can vary slightly by year, so check the manual for your specific vehicle.
- Oil capacity with filter: 4.5 quarts (4.3 liters)
- Oil capacity without filter: about 4.0–4.2 quarts (3.8–4.0 liters) depending on drain extent
- Recommended oil viscosity: 0W-20 full synthetic (per Lexus specifications)
When performing an oil change, use the recommended full-synthetic 0W-20 oil, and replace the oil filter to maintain proper engine protection and performance.
Model-year notes and market considerations
Market-specific differences
Most NX300h models across recent years share the same 2.5-liter engine and similar oil capacity. However, some early or market-specific versions may show minor differences. Always consult the owner’s manual for your exact year, or check the official Lexus service documentation for your region.
For quick reference, dealers and manuals typically list 4.5 quarts (4.3 liters) as the standard capacity with filter, with slight variance if the drain was partial or if multiple filters were replaced. If you’ve recently done a major engine service, re-check with the dealership to confirm the precise amount required.
Practical steps for performing an oil change
In addition to knowing the capacity, follow proper procedure to ensure you add the correct amount and use the right oil type.
- Park on level ground and allow the engine to cool before draining oil.
- Drain old oil completely and replace the oil filter.
- Add oil gradually, starting with about 4.0 quarts (depending on drain), then recheck level with the dipstick; continue adding small amounts until the level is within the recommended range.
Following these steps helps ensure you use the correct amount and maintain optimal engine protection.
Checking oil level and maintenance tips
Beyond capacity, keeping a correct oil level supports engine longevity. Use the vehicle’s dipstick or on-board computer readout to verify the level after a refill, and avoid overfilling, which can cause foaming and other issues. Adhere to the manufacturer’s oil-change interval and use the specified 0W-20 full synthetic oil for best results.
Summary
The Lexus NX300h typically requires about 4.5 quarts of engine oil with a filter when performing a standard oil change, using a 0W-20 full-synthetic oil. Always verify the exact specification for your vehicle’s year and market in the owner’s manual or with a Lexus dealer, and follow the recommended maintenance intervals for oil changes.
