Lexus RX 350
Data verified by Nick Marchenko, PhD
Maintaining the engine oil in your Lexus RX 350 is crucial for optimal performance and longevity. This model, produced between 2007 and 2022, offers four engine options, each with specific oil requirements. The 2GR-FE (3.5L V-6) engines from 2007 to 2009 require either 6.4 quarts of 5W-30 oil or 6.4 quarts of 0W-20 oil for models from 2010 to 2015. The newer 2GR-FKS (3.5L V-6) engines from 2016 to 2022 have slightly lower oil capacities of 5.7 to 5.8 quarts, depending on the year, and utilize 0W-20 oil.
In addition to oil maintenance, it's essential to monitor coolant levels, with capacities ranging from 8.9 to 10.5 quarts depending on the engine variant. Regular oil changes not only ensure your engine runs smoothly but also help maintain the vehicle's resale value. Always refer to your owner's manual for the specific requirements of your engine type.

What type of oil does the Lexus RX 350 use?
The Lexus RX 350 uses either 0W-20 or 5W-30 engine oil, depending on the engine variant and production year. The 2GR-FE engine from 2010 to 2015 requires 0W-20, while the earlier models from 2007 to 2009 use 5W-30.
How many quarts of oil does the Lexus RX 350 take?
The oil capacity for the Lexus RX 350 varies by engine. The 2GR-FE engines from 2007 to 2009 take 6.4 quarts, while the 2GR-FKS engines from 2016 to 2022 require 5.7 to 5.8 quarts.
How often should I change oil in a Lexus RX 350?
It's generally recommended to change the oil in your Lexus RX 350 every 5,000 to 7,500 miles, depending on driving conditions and oil type. Always refer to your owner's manual for specific intervals.
What is the coolant capacity of the Lexus RX 350?
The coolant capacity for the Lexus RX 350 varies by engine. The 2GR-FE engines require 10 quarts, while the 2GR-FKS engines need 10.5 quarts.
Does the Lexus RX 350 need synthetic oil?
While the Lexus RX 350 can use conventional oil, it is recommended to use synthetic oil, especially for the 0W-20 viscosity, as it provides better protection and performance.
What happens if I use the wrong oil viscosity in my Lexus RX 350?
Using the wrong oil viscosity can lead to inadequate lubrication, increased engine wear, and potential overheating. Always use the recommended viscosity for your specific engine.
What is an oil life monitor and how does it work?
An oil life monitor is a system that tracks engine operating conditions and calculates when an oil change is necessary. It considers factors like temperature, driving habits, and engine load.
Can I mix synthetic and conventional oil?
While you can mix synthetic and conventional oils, it is not recommended as it can reduce the benefits of synthetic oil. It's best to stick with one type for optimal performance.
How do I know if my Lexus RX 350 has an oil leak?
Signs of an oil leak include oil spots under the vehicle, a burning oil smell, or a drop in oil levels on the dipstick. Regularly checking your oil level can help detect leaks early.
What causes excessive oil consumption?
Excessive oil consumption can be caused by worn piston rings, valve seals, or gaskets. It can also result from using the wrong oil viscosity or not changing the oil regularly.
Should I check my oil when the engine is hot or cold?
It's best to check your oil when the engine is warm but not hot. This allows the oil to circulate and gives a more accurate reading on the dipstick.
What is the difference between an oil change and a flush?
An oil change involves draining the old oil and replacing it with new oil, while an oil flush is a process that cleans the engine by removing sludge and deposits before changing the oil.
