What oil does a Lexus UX take?
The Lexus UX typically uses 0W-20 full‑synthetic engine oil. In most markets this is the standard grade, though some climates or regional specifications may permit 5W-30 as an alternative per the owner’s manual. The oil capacity is about 3.6 quarts (3.4 liters) with the filter. Always confirm the exact requirement for your VIN with the owner's manual or a Lexus dealer.
This article explains the recommended oil type, capacity, maintenance intervals, and how to verify the correct specification for both the UX 200 and the UX 250h hybrid, to help you keep the compact crossover running smoothly.
Oil type and grade
Below are the core specifications you should follow when selecting oil for the Lexus UX. The guidance focuses on the most common, manufacturer-approved option, with notes on alternatives where applicable.
- Recommended grade: 0W-20 full synthetic engine oil
- Alternative (in some markets): 5W-30 may be acceptable under certain climate conditions per the owner's manual
- Certifications: API SN (or newer) and ILSAC GF-5 compliance
- Quality and compatibility: use a Lexus-approved (OE) or OEM-recommended synthetic oil
- Filter: pair the oil with a matching engine oil filter (OEM or equivalent) when servicing
Using the specified grade helps ensure proper lubrication, fuel efficiency, and emissions compliance. If you're unsure about local approvals, check your dealership or the vehicle's manual for region-specific guidance.
Capacity and maintenance intervals
Understanding the engine oil capacity and change intervals helps you plan your maintenance and avoid overfilling or under-lubricating the engine.
- Oil capacity (including the filter): approximately 3.6 quarts (3.4 liters)
- Normal service interval: about every 10,000 miles (16,000 kilometers) or 12 months, whichever comes first
- Severe service interval: more frequent changes may be recommended in extreme temperatures, heavy city traffic, or frequent short trips
- Maintenance practice: always use the dipstick to confirm level and top up as needed within the recommended range
- Oil and filter changes: use OEM/or approved filters and fresh oil to maintain warranty coverage
Adhering to these intervals and using the correct oil helps protect the engine, maintain performance, and support long-term reliability in the UX lineup.
How to verify the right oil for your vehicle
To ensure you’re using the correct oil for your specific UX model and market, follow these steps. This is especially important if you own a UX 200 or UX 250h, where regional specs can vary slightly.
- Consult the owner’s manual or the vehicle’s information label for the exact viscosity and specification (grade, API/ILSAC, and any regional notes).
- Check the VIN-specific maintenance page or contact a Lexus dealership to confirm regional approval of 0W-20 vs. alternatives.
- Choose a high-quality full-synthetic oil that meets API SN and ILSAC GF-5, and ensure it’s compatible with hybrid and non-hybrid engines if applicable.
- Replace the oil filter with an OEM or approved equivalent during every oil change.
- Record the service in your maintenance log and monitor oil level between services.
Following these steps helps ensure you’re aligned with Lexus’ specifications for your vehicle variant and climate.
Hybrid specifics for the UX 250h
The UX 250h hybrid shares the same fundamental engine oil requirements as the UX 200 in most markets. The recommended oil grade is typically 0W-20 full synthetic, with similar capacity and maintenance intervals. Always verify and follow the regional manual, especially for climate-related adjustments or alternative approvals.
- Oil grade: 0W-20 full synthetic (same as non-hybrid models in most regions)
- Capacity: around 3.6 quarts (3.4 liters), including filter
- Maintenance: standard oil change intervals apply, with potential adjustments for severe conditions
Hybrid systems add complexity to drivability and efficiency, but they do not usually change the oil specification itself. Always prioritize the factory-recommended grade and interval to protect both the gasoline engine and the hybrid powertrain.
Summary
For most Lexus UX models, the standard oil is 0W-20 full synthetic, with an approximate capacity of 3.6 quarts (3.4 liters) including the filter. Follow normal maintenance intervals of roughly 10,000 miles / 12 months, and shorten intervals under severe driving conditions. If you’re in a region with different specifications, consult the owner’s manual or a Lexus dealer to confirm the exact requirements for your VIN, and always use OEM filters and approved oils.
