Oil Maintenance & Service Tips
Regular oil checks and changes on the Lexus UX are important for engine maintenance, especially with low-viscosity synthetic oil. Always confirm the engine (UX 200, UX 250h, or UX 300h) before choosing oil capacity, filter, and viscosity.
Check the oil level with the dipstick on level ground, after the engine has been warmed and shut off for a few minutes. When performing an oil change, replace the oil filter, install a new drain plug gasket, and torque the plug to about 27 lb-ft (37 N·m). For vehicles that see short trips, hot climates, dusty roads, or frequent towing, shorten the oil change interval below the nominal 10,000 miles or 12 months.
Normal vs severe service
| Driving Condition | Suggested Oil Change Interval |
|---|---|
| Normal driving (mixed city/highway, moderate climate) | Up to 10,000 miles or 12 months with full synthetic oil. |
| Severe driving (extreme temperatures, short trips, heavy traffic, dusty roads, frequent towing) | About 5,000 miles or 6 months, even with synthetic oil. |
FAQs
What kind of oil does a Lexus UX use?
Most Lexus UX 200, UX 250h, and UX 300h engines are specified for full synthetic engine oil that meets current API SN or SP and ILSAC GF-6 standards. Lexus generally recommends 0W-16 as the primary viscosity, with 0W-20 allowed as an alternative where listed in the owner’s manual.
How much oil does a Lexus UX take?
Gasoline UX 200 models with the 2.0L M20A-FKS engine typically use about 4.9 qt (4.6 L) of oil with filter, while UX 250h and UX 300h hybrids with the M20A-FXS use about 4.5 qt (4.3 L). Actual capacity can vary slightly, so always use the dipstick after refilling and adjust to the full mark.
What is the recommended oil type for a Lexus UX 250h or UX 300h?
The UX 250h and UX 300h hybrid engines are designed for full synthetic low-viscosity oil, typically SAE 0W-16 meeting API SM–SP and ILSAC GF-6 or equivalent. Using oil that meets Lexus and Toyota specifications helps protect the hybrid engine under frequent start-stop operation.
What is the oil change interval for a Lexus UX?
In many markets, Lexus specifies oil change intervals up to 10,000 miles or 12 months when using approved synthetic oil in the UX. For vehicles operated under severe conditions, a shorter interval of about 5,000 miles or 6 months provides a more conservative maintenance schedule.
Which oil filter should I use on a Lexus UX?
OEM Lexus/Toyota cartridge filters such as 90915-YZZF2 or 90915-YZZN1 are commonly used on UX 200 and UX 250h engines. Aftermarket filters that match these part numbers, including Mobil 1 M1-103A, K&N SO-1003, and FRAM FE4967, are widely listed as compatible equivalents.
Conclusion
Across all model years, the Lexus UX family uses compact 2.0L M20A engines with relatively small oil capacities, typically around 4.5 to 4.9 qt (4.3 to 4.6 L) with filter depending on whether the vehicle is a UX 200 gasoline model or a UX 250h/UX 300h hybrid. The recommended oil is full synthetic 0W-16 (with 0W-20 permitted in some manuals), and observing the correct capacity, viscosity, and maintenance interval is important to maintain lubrication, control deposits, and protect the engine under all operating conditions. Using manufacturer-approved oil and filters and following proper service procedures will help keep the Lexus UX engine reliable and efficient over long service life.
