It uses 0W-20 synthetic engine oil.
The 2019 Lexus NX 300, which features a 2.0-liter turbocharged engine, is designed to run on 0W-20 full synthetic oil. This viscosity helps with fuel economy and cold-start protection while meeting typical Lexus/Toyota engine specifications. Always confirm the exact specification on your vehicle’s oil filler cap or in the owner’s manual, as regional variations can occur.
Oil specification and viscosity
The recommended oil grade for the NX 300 is 0W-20 full synthetic. This grade is chosen to balance performance, protection, and efficiency across common climate ranges. Use an oil that meets API SN or newer and is suitable for gasoline engines; many shoppers opt for well-known brands that explicitly certify 0W-20 for use in Lexus/T Toyota engines. If you’re unsure, consult the owner’s manual or contact a Lexus service advisor to confirm the exact specification for your market.
Oil capacity and maintenance interval
The oil capacity with the filter for the NX 300 is typically around 4.6–4.8 quarts (roughly 4.4–4.6 liters). For normal driving with synthetic oil, the suggested change interval is about every 10,000 miles (16,000 kilometers) or 12 months, whichever comes first. In severe conditions—such as frequent short trips, extreme temperatures, or heavy towing—more frequent changes are advised.
Practical tips for selecting oil
Choose a reputable brand of 0W-20 synthetic oil and replace the oil filter when performing a drain. Common options include Mobil 1 0W-20, Castrol EDGE 0W-20, Pennzoil Platinum 0W-20, and other major brands that certify 0W-20 for Toyota/Lexus engines. Always verify the product label to ensure it meets the correct specification for your NX 300 before purchase.
Conclusion
For a 2019 Lexus NX 300, the standard oil specification is 0W-20 synthetic. Following this recommendation supports engine protection, efficiency, and warranty considerations. When in doubt, refer to the owner’s manual or ask a Lexus service professional for the precise oil specification and capacity for your vehicle.
Summary
In short: use 0W-20 synthetic oil, expect a fill of about 4.6–4.8 quarts with a new filter, and plan oil changes roughly every 10,000 miles under normal driving—more often in demanding conditions. Always verify the exact spec in your manual or with a dealership.
