Can I use 5W-20 in a Lexus?
When it comes to maintaining your Lexus, choosing the right engine oil is crucial for ensuring optimal performance and longevity. Many Lexus owners wonder if they can use 5W-20 oil in their vehicles. In this article, we’ll explore whether this oil is suitable for your Lexus and provide guidance on making the best choice for your car.
Understanding Engine Oil Grades
Engine oil grades, such as 5W-20, are determined by the Society of Automotive Engineers (SAE) and indicate the oil's viscosity. The first number, "5W," refers to the oil's viscosity in cold temperatures, while the second number, "20," represents its viscosity at operating temperature. The right oil grade ensures proper lubrication, reduces engine wear, and maintains fuel efficiency.
What Does Lexus Recommend?
Lexus, like most manufacturers, specifies the recommended oil grade for each model in the owner’s manual. For many Lexus models, the recommended oil grade is 0W-20, which is designed to provide excellent performance in a wide range of temperatures. However, some older Lexus models may allow for 5W-20 as an alternative, especially in warmer climates.
Can You Use 5W-20 in Your Lexus?
The short answer is: it depends on your Lexus model and its specific requirements. Here are some key considerations:
- Check the Owner’s Manual: Always refer to your Lexus owner’s manual for the manufacturer’s recommended oil grade. If 5W-20 is listed as an acceptable alternative, you can use it without concerns.
- Climate Conditions: If you live in a region with mild or warm temperatures, 5W-20 may perform adequately. However, in colder climates, 0W-20 is often preferred for better cold-start performance.
- Warranty Implications: Using an oil grade not recommended by Lexus could potentially void your warranty. Be sure to follow the manufacturer’s guidelines to avoid any issues.
Why 0W-20 Is Often Preferred
Lexus typically recommends 0W-20 for its newer models because it offers several advantages:
- Improved Fuel Efficiency: The lower viscosity of 0W-20 reduces friction, leading to better fuel economy.
- Enhanced Engine Protection: It provides superior lubrication, especially during cold starts, which is critical for reducing engine wear.
- Compatibility with Modern Engines: Many Lexus engines are designed to work optimally with 0W-20, ensuring peak performance.
Final Thoughts
While 5W-20 may be suitable for some Lexus models under specific conditions, it’s always best to follow the manufacturer’s recommendations. If you’re unsure about which oil to use, consult your owner’s manual or reach out to a trusted auto service professional.

Frequently Asked Questions
Which engine oil is best for a Lexus?
Brand is endlessly debatable, but Lexus recommends full synthetic, 0w-20, to maintain change interval of every 10000 miles under normal use.
Can I use 5w30 instead of 5w20 for a high mileage car?
If 5w20 is not available there is absolutely nothing wrong in using 5w30. And for a high mileage car 5w30 will offer better protection depending on the condition of the engine. Even some manufacturers that recommend 5w20 still recommend 5w30 if car is old and will be driven in temperate regions most of the times.
Can I use 5w20 instead of 0W20 Toyota Tacoma?
So what is the recommended oil type for the Toyota Tacoma? Like many other Toyota vehicles such as the RAV4, the Tacoma runs best on synthetic oil with a grade of SAE 0W-20 or SW 5W-20.
Can I mix 5W20 with 5W30?
In nearly all cases, you can use whatever motor oil is available as long as it's clean and from a sealed container. Mixing oils is virtually always better than running on low oil.
Can I use 5W20 instead of 0W20 in hot weather?
If there is no chance for the weather to get that much cold, you can exchange the oil. However, it's better to use the 0W variant in extreme weather because the engine may suffer difficulties at the start if you use the 5W version.
What's the difference between 5w20 and 5w30 full synthetic?
As already said, both 5W-20 and 5W-30 are the same viscosity when the engine is cold. The 5W-20, however, will remain a little thinner once you reach operating temperature to help improve fuel economy and flow fast enough to fill the tight tolerances in the engine.
What vehicles take 5W20?
Mobil 1™ 5W-20 is recommended by ExxonMobil for all types of modern gasoline-powered vehicles, including high-performance turbocharged, supercharged, multi-valve fuel injected engines found in passenger cars, SUVs, light vans and light trucks.
What happens if I put 5w20 in my car instead of 5w30?
It's fine. Most ordinary 5W30's will shear down close to a 20W after the first 1000 miles anyway--and any 5W20 will be more shear resistant, by definition. You have nothing to worry about.
Can I put 5W-20 in my 0W-20 engine?
If SAE 0W-20 synthetic oil is not available, SAE 5W-20 conventional oil may be used. However, it must be replaced with SAE 0W-20 synthetic oil at the next oil change.
Why is an oil change for a Lexus so expensive?
The higher cost of a Lexus oil change can be attributed to several factors. These include the use of synthetic oil, higher labor costs at a dealership, and the inclusion of additional services and inspections.
