What is the Oil Type and Capacity of the 2021 Lexus RX350?

What is the difference between 0w-20 and 5w-20 oil?

The significant difference between the 0W-20 and the 5W-20 is the level of thickness of the oil. 0W-20 is much thinner compared to the 5W-20, making it perform better in extremely cold conditions than the latter. It can still flow smoothly through the engine’s parts during the cold and keeps a stable condition without getting thicker. 

Also, the 5W-20 oil has its advantage; it performs better in temperatures between -22°F to 68°F. 

Below are some notable differences to better understand the difference between these two oils. 

1. Hot viscosity

When we talk about oil viscosity, we mean the flow level for each oil type under a certain temperature. The 0W-20 and 5W-20 oil act as SAE 20 weight oil during the summer. They can also operate up to 68 °F. It makes both oil resistant to extreme heat and burning easily. 

2. Cold viscosity

Unlike the hot viscosity, both oils do not perform the same under extremely cold circumstances; 0w-20 motor oil acts as an SAE-weight oil when subjected to extremely cold circumstances. On the other hand, the 5W-20 oil acts as an SAE 5W weight oil when subjected to extremely cold weather conditions. 

According to SAE, the lower the number that comes before the W, the more it can perform under colder temperatures. It makes the 0W-20 better in the cold because it has a much thinner structure than the 5W-20.  

3. Fuel economy 

The 0W-20 may give you a slightly better oil performance regarding fuel efficiency than the 5W-20. However, when observed correctly, the performance of the oil is more or less the same regarding fuel consumption. The slight difference in the fuel performance is the difference in the level of thickness between the two oils. You can receive maximum fuel efficiency and excellent fuel economy if you get the synthetic type of both oils. 

4. Performance 

Their performance depends solely on the weather condition that they are subjected to. The 0W-20 and 5W-20 oil will perform better in lower temperatures because it has a thinner structure. When it comes to cold starts, the 0W-20 performs better. You can also be sure that it will protect your engine from buildup, carbon deposits, engine wear, and more problems with using engine oil. 

On the other hand, the 5W-20 performs well in cold weather conditions and excellently in warmer temperatures. Due to its thicker structure than the 0W-20, it has a better resistance to hotter temperatures. 

5. Price 

Regarding pricing, you might find the 5W-20 cheaper than the 0W-20 because the 5W-20 oil, whether in whole or semi-synthetic oil, is not as stable as the latter. The price of the motor oil can range depending on the brand and supplier. 

How do you reset the oil maintenance light on a Lexus RX 350?

Suppose you have the maintenance light illuminated. The light comes on due to the miles calculated and does have any way of knowing when you have changed or topped up the oil. When the light is still on after changing the oil, you will have to reset the light to turn it off. 

Below are easy-to-follow steps to reset the maintenance light on your Lexus RX 350. 

1. Switch the ignition to the on position, and press the Start button twice without pressing down the brake pedal. 
2. Find the ODO/Trip button, which can be seen on the left side of the steering wheel, and press it until you are on TRIP A.
3. Turn off the ignition and ensure your leg is off the brake pedal when you push the start or stop button. Do this until it powers down. 
4. Turn on the turn-on ignition again by pressing the brake pedal, but this time do it while pressing down on the ODO/TRIP button. 
5. Hold the ODO/TRIP button; you will see a blinking backward light, which will change to zero. At this point, the reset has been completed. 

Is Lexus transmission fluid lifetime?

Yes, some Lexus transmission fluid is lifetime, but it is not what you think. When Lexus refers to the fluid as a lifetime, it means that the transmission fluid will last for the period of warranty validation. It does not necessarily mean that you will not need to change the fluid throughout the life use of the vehicle. You must check your vehicle’s manual to get the specified interval for transmission fluid change.
