Lexus UX uses genuine Lexus oil with the specification SAE 10W30 SM. The functions of the oil include lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. Taking the Lexus UX 2020 200 Special Edition as an example, it is a 5-door, 5-seater compact SUV with dimensions of 4495mm in length, 1840mm in width, and 1540mm in height, a wheelbase of 2640mm, and a fuel tank capacity of 47 liters. The Lexus UX 2020 200 Special Edition is equipped with a 2.0L naturally aspirated engine, paired with a CVT continuously variable transmission, delivering a maximum power of 127 kW and a maximum torque of 207 N·m.

My Lexus UX has been running for over three years, and when I pop the hood, I swear by 0W-20 full synthetic oil. This oil has low viscosity, ensuring quick cold starts and smooth driving in winter; its excellent fluidity under high summer temperatures protects the hybrid engine. The manual recommends ILSA-certified oil, so I opt for Mobil or Shell, sticking to an oil change interval of around 10,000 miles and checking the oil level every six months. I also pay attention to driving habits, avoiding frequent hard accelerations to maintain oil stability. To save money, I bring my own oil to the shop for changes—adding a filter only costs a few dozen bucks. Using the wrong oil is a no-go; some have tried 5W-30 but reported slightly increased fuel consumption and louder engine noise, so I stick to the factory recommendation to ensure long engine life.

From a maintenance perspective, the UX hybrid engine is suitable for 0W-20 full synthetic oil. This low-viscosity oil is designed to reduce friction and improve fuel efficiency; the oil capacity is approximately 4.5 liters, with a recommended change interval of 8,000-10,000 miles per the manual. I use API SN-certified oil to ensure compatibility; oil performance is crucial during temperature changes—preventing thickening in summer and freezing in winter. Checking the oil level is simple: turn off the engine, wait 10 minutes, and check the dipstick marks; regular oil changes prevent carbon buildup from damaging pistons. The hybrid system is precision-engineered, and using premium oil can extend the lifespan of the battery and engine linkage components.

As a new owner of a UX, the 4S dealership advised me to simply choose 0W-20 full synthetic oil. The oil bottle is labeled with the Lexus-certified ILSA designation; the viscosity is suitable for hybrid vehicles, ensuring smooth and quiet engine operation. According to the maintenance manual, change the oil every 7,500 miles, with an oil quantity of approximately 4-5 liters. I've learned to perform a simple oil check myself—pull out the dipstick when the engine is cold to see if the oil level is normal; avoid using conventional mineral oil as it may affect the engine warranty. Hybrid engines are particularly delicate, so proper maintenance ensures worry-free operation.
