What oil does Lexus 300h hybrid take?

The Lexus 300h hybrid uses a full-synthetic 0W-20 engine oil.

This article explains the recommended oil grade, the standards it must meet, and practical maintenance tips for keeping the 300h’s petrol engine and hybrid drive well-lubricated across typical driving conditions.

Oil specification for the Lexus 300h

Key requirements at a glance:

• Oil grade: 0W-20 synthetic (full synthetic preferred).


• Standards: API SN or newer; ILSAC GF-5 or newer.


• Engine compatibility: matches the 2.5L hybrid powertrain used in the 300h family.


• Lubricant type: do not use mineral/mineral-based blends; avoid non-synthetic oils unless explicitly approved by Lexus.


• Change interval: follow the maintenance schedule in your manual (commonly around 10,000 miles / 12 months under normal driving; more frequent under severe conditions).

Adhering to these specifications supports efficient operation, preserves fuel economy, and protects the hybrid powertrain components.

Why 0W-20 is recommended

0W-20 helps reduce engine friction during startup and at operating temperature, contributing to better fuel efficiency and smoother hybrid performance. It aligns with the engineering goals of Lexus hybrids and is widely adopted across contemporary Lexus models.

Market notes

In most markets, Lexus specifies 0W-20 synthetic oil for the 300h. If you drive in areas with extreme temperatures or different climate guidelines, always check your owner's manual or consult a Lexus dealer to confirm the correct grade and viscosity for your vehicle and year.

Maintenance tips for oil care

To keep the oil performing optimally in a hybrid system, follow these practices:

1. Regularly check the oil level with the dipstick when the engine is cool, and top up with the same grade if needed.


2. Change the oil and filter at the interval specified in your owner's manual; use a genuine Lexus or equivalent high-quality synthetic oil that meets API SN or newer and ILSAC GF-5 or newer.


3. Use only the recommended grade; do not substitute with mineral oil or other viscosities unless explicitly approved by Lexus for your model/year.


4. Consider more frequent changes under severe driving conditions, heavy city traffic, towing, or extreme temperatures.

Proper oil maintenance helps protect the engine and hybrid components while preserving efficiency and smooth operation.

Summary

For the Lexus 300h hybrid, the recommended oil is a full-synthetic 0W-20 that meets current API and ILSAC standards. Always confirm the exact specification and service intervals in your owner’s manual or with a Lexus dealer, as requirements can vary by market and model year.

What kind of oil does a 2014 Lexus ES300h take?

The recommended oil for a 2014 Lexus ES300h is 0W-20 full synthetic oil, with a capacity of 4.6 quarts when including the filter. While 5W-20 may be used in an emergency, you must switch back to 0W-20 at the next oil change.
 

• Oil type: SAE 0W-20 full synthetic motor oil 
• Capacity: 4.6 quarts (with filter) 
• Note on alternative: If 5W-20 is used, it must be replaced with the correct 0W-20 oil at the next service.

What kind of oil does a Lexus IS 300 take?

The oil type for a Lexus IS300 depends on the model year: newer models (approx. 2017+) generally use 0W-20 full synthetic oil, while older models, like the 2005, may use 5W-30. Always check your owner's manual to confirm the exact specification, but generally, the recommended viscosity is 0W-20 for most modern IS300s. 
Newer models (e.g., 2017+)

• Oil Viscosity: 0W-20 
• Oil Type: Full Synthetic 
• Note: In a pinch, 5W-20 can be used temporarily, but you must switch back to 0W-20 at the next oil change. 

Older models (e.g., 2005)

• Oil Viscosity: 5W-30 
• Note: 5W-30 is the preferred grade, but check your owner's manual for the most accurate information. 

General recommendations for all models

• Always check your owner's manual: This is the most reliable source for your specific vehicle's requirements. 
• Use the correct oil capacity: After refilling the oil, always check the level using the dipstick. 
• Use a new drain plug washer: This is crucial for preventing leaks. 
• Consider full synthetic: It can provide better engine protection and performance, especially for modern vehicles.
