Maximize your 4runner’s mileage: the ultimate guide to selecting the right oil

Maintaining your Toyota 4Runner is crucial for its longevity and performance. Among the essential maintenance tasks, choosing the right oil is paramount. In this comprehensive guide, we will explore the specific oil requirements for the Toyota 4Runner, providing you with the knowledge to make informed decisions about your vehicle’s lubrication needs.

Understanding Oil Viscosity

Oil viscosity, measured in SAE (Society of Automotive Engineers) grades, indicates the oil’s thickness and flow characteristics. The first number in the SAE grade (e.g., 5W) represents the oil’s flowability at cold temperatures, while the second number (e.g., 30) indicates its viscosity at operating temperatures.

Toyota 4Runner Oil Requirements

Toyota recommends using genuine Toyota motor oil for optimal performance and longevity. The specific oil requirements vary depending on the model year, engine type, and driving conditions.

2023 Toyota 4Runner

• SAE 0W-20
• API SN PLUS or ILSAC GF-6B

2022 Toyota 4Runner

• SAE 0W-20
• API SN PLUS or ILSAC GF-6A

2021 Toyota 4Runner

• SAE 0W-20
• API SN PLUS or ILSAC GF-5

2020 and Older Toyota 4Runners

• SAE 5W-30
• API SN or ILSAC GF-5

Synthetic vs. Conventional Oil

Synthetic oils are engineered to meet specific performance criteria, offering advantages such as:

• Improved flowability at low temperatures
• Reduced friction and wear
• Extended oil change intervals

Conventional oils are refined from crude oil and are typically less expensive than synthetic oils. However, they may not provide the same level of protection and longevity.

Oil Change Intervals

Toyota recommends following the maintenance schedule outlined in your owner’s manual for oil change intervals. Generally, oil changes are recommended every 5,000-7,500 miles or 6 months, whichever comes first. However, severe driving conditions may require more frequent oil changes.

Checking Oil Level

Regularly checking your oil level is essential to prevent engine damage. To check the oil level:

1. Park the vehicle on a level surface.
2. Wait 5-10 minutes after turning off the engine to allow the oil to settle.
3. Pull out the oil dipstick, wipe it clean, and reinsert it fully.
4. Pull out the dipstick again and check the oil level. The oil should be between the “MIN” and “MAX” marks on the dipstick.

Top-Off Oil

If the oil level is low, add the recommended oil type and viscosity. Do not overfill the engine with oil.

In a nutshell

Choosing the right oil for your Toyota 4Runner is crucial for ensuring its optimal performance and longevity. By understanding oil viscosity, Toyota’s oil requirements, and the benefits of synthetic vs. conventional oils, you can make informed decisions about your vehicle’s lubrication. Remember to check your oil level regularly and adhere to the recommended oil change intervals to keep your 4Runner running smoothly for years to come.

Frequently Asked Questions

Q: What is the difference between SAE 0W-20 and SAE 5W-30 oil?
A: SAE 0W-20 oil is thinner and flows more easily at cold temperatures than SAE 5W-30 oil. It is recommended for newer vehicles and provides better fuel economy. SAE 5W-30 oil is thicker and may be better suited for older vehicles or those operating in extreme temperatures.

Q: Can I use a different brand of oil than Toyota?
A: Yes, you can use a different brand of oil as long as it meets the specifications recommended by Toyota. However, using genuine Toyota motor oil ensures optimal performance and protection.

Q: How often should I change my oil filter?
A: Toyota recommends changing the oil filter every time you change the oil. A clean oil filter helps remove contaminants from the oil and ensures proper lubrication.
