Lexus RX 350 Engine Oil Reviews & Buying Guide
When selecting engine oil for your Lexus RX 350, consider the mileage of the Lexus RX 350 and the condition of the engine. For a new Lexus RX 350 and a low mileage vehicle, it is best to use synthetic engine oil.
Synthetic oil for Lexus RX 350
Synthetic oil has a significant impact on Lexus RX 350’s fuel consumption due to its physical and chemical characteristics. Because of its high fluidity and friction properties, friction losses in the Lexus RX 350 engine are significantly reduced. This means that more of the energy released in the combustion process will be transferred directly to the wheels. As a result, the gas pedal in the Lexus RX 350 becomes more responsive with less fuel consumption.
When using synthetic oil in the Lexus RX 350, there is less friction in the engine and transmission at low temperatures than when using high viscosity oil. This provides improved Lexus RX 350 engine starting performance, fuel economy, and lower emissions when the Lexus RX 350 is operated in cold cycle mode.
Lexus RX 350 0w-20 Engine Oil
For new Lexus RX 350 vehicles with less than 50,000 miles, we recommend using a synthetic 0w-20 viscosity engine oil that meets the API SP, ILSAC GF-6 specification.

Lexus RX 350 Engine Oil Review
Engine Oil Type for Lexus RX 350
There are two types of engine oils: conventional oil and synthetic oil. Lately, Lexus RX 350 owners choose synthetic motor oil simply because of its quality and good molecular consistency.
Synthetic engine oil for Lexus RX 350 has an improved molecular formula, due to which it practically does not oxidize, does not react (for example, with engine oil seals), has an improved viscosity, also practically does not oxidize.
Synthetic oils for the Lexus RX 350 have many additives that help increase engine compression as well as reduce fuel consumption. Winter starting the engine is much easier since the oil does not thicken as much at low temperatures.
The only disadvantage of synthetic oil is its high price compared to conventional oil. We recommend using synthetic oil in newer Lexus RX 350 models, and conventional motor oil in older Lexus RX 350 models.
