Does Lexus ES 350 require synthetic oil?

Yes. For most recent ES 350 models, Lexus specifies synthetic oil, with 0W-20 being standard on newer cars and 5W-30 often referenced for older generations depending on market and year.

Oil specifications in the ES 350 have evolved across generations. The exact viscosity and whether synthetic is required can vary by model year and region, so it’s important to consult your vehicle’s owner’s manual or a Lexus dealer to confirm the correct grade for your car. This article outlines the general guidance by generation and how to verify the correct specification for your ES 350.

Oil recommendations by generation

The following paragraphs summarize the official guidance you’ll typically find in Lexus owner manuals for different ES 350 model years.

• Current generation (2019–present ES 350): 0W-20 full synthetic oil is recommended as the standard lubrication. Always confirm the exact grade in your manual or on the oil cap.


• Mid-generation (2013–2018 ES 350): 5W-30 synthetic oil is commonly recommended in many markets; some regions may list 0W-20 as acceptable depending on climate and specifications. Check your manual for the precise requirement.


• Early-generation (2007–2012 ES 350): 5W-30 synthetic oil was typically advised, with some markets permitting 5W-20. Verification in the owner’s manual is essential for the exact grade.

Note: If you own a variant such as the ES 300h hybrid, the recommended oil family remains synthetic, but verify the exact viscosity for your year and engine version in the manual or from a dealer.

How to confirm the correct oil for your ES 350

Because viscosity requirements can change by year and market, the definitive source is the owner’s manual and the oil specification sticker under the hood. You can also contact a Lexus dealership or service center for the precise grade and service intervals for your vehicle.

Additional considerations

Beyond choosing the correct viscosity, use a high-quality full synthetic oil that meets current industry standards (for example, ILSAC GF-6 and API SN+/SP as applicable to your year). Use a genuine or high-quality equivalent oil filter, and follow the factory-recommended service intervals as stated in your manual.

Summary

In short, the Lexus ES 350 is designed to run on synthetic oil, with 0W-20 the standard recommendation on the latest models and 5W-30 often cited for older generations. Always verify the exact grade for your year and region by consulting the owner’s manual or a Lexus dealer, and follow the maintenance schedule to protect the engine.

Should I use full synthetic oil in a Lexus?

Genuine Lexus Oil Change
At Bergstrom Lexus of Madison, we recommend full synthetic oil changes. Synthetic oil is designed to have a longer lifespan than conventional oil, allowing you to take advantage of a longer interval between oil changes.

Does the Lexus IS 350 use synthetic oil?

For newer models, the preferred viscosity is 0W-20 synthetic. This oil grade has higher engine wear protection, particularly under high temperatures, and can improve fuel economy. Older Lexus models, such as the 2005-2010 IS250 and 2006-2013 IS350, require 5W-30 oil.

How often does a Lexus ES 350 need an oil change?

The oil change interval for a Lexus ES 350 is every 10,000 miles or 12 months using full synthetic oil, while a conventional oil change should be done every 5,000 miles or 6 months. However, you should have a service every 5,000 miles or 6 months for other checks like tire rotation, even if you are using full synthetic oil. The ideal interval can also be affected by driving habits and climate.

Recommended oil change intervals

• Full synthetic oil: Every 10,000 miles or 12 months.
• Conventional oil: Every 5,000 miles or 6 months. 

Additional services and considerations

• Every 5,000 miles / 6 months: Perform a 5,000-mile service for tasks like tire rotation, fluid level checks, and a brake inspection, regardless of the oil type used. 
• Driving habits: If you frequently drive in stop-and-go traffic, on dusty roads, or tow heavy loads, you may need to change your oil more frequently. 
• Consult your owner's manual: Your vehicle's owner's manual will have the most specific information based on your exact model and year.

What kind of oil should I put in my Lexus ES 350?

The recommended oil for a Lexus ES 350 depends on the model year: most newer models require SAE 0W-20 full synthetic oil, while older models typically use SAE 5W-30 conventional oil. It is best to always check your owner's manual for the specific recommendation for your vehicle's year, but the 0W-20 synthetic is preferred for modern ES 350s for better performance and fuel economy.
 
For newer models

• Oil Type: SAE 0W-20 full synthetic motor oil
• Benefits: Offers excellent engine protection and fuel efficiency 

For older models

• Oil Type: SAE 5W-30 conventional oil 
• Note: Some sources and videos may suggest using a synthetic 5W-30 for added protection, especially in hotter climates, but it's important to consult your owner's manual first. 

Important considerations

• Always check your owner's manual: to confirm the specific oil type and capacity for your exact vehicle. 
• Use a premium-grade synthetic oil: for newer models to maximize performance and protection, as recommended by Lexus. 
• Use the correct oil filter: along with the oil change.
