Is it ok if I put 5w20 instead of 0W20?
As a car owner, you might find yourself in situations where the exact oil specified in your vehicle's manual isn't readily available. A common question we hear at Kevin's Autos is whether it's acceptable to use 5W-20 motor oil instead of 0W-20. While these oils are similar, there are important factors to consider before making the switch.
Understanding the Difference Between 0W-20 and 5W-20
Both 0W-20 and 5W-20 are multi-grade oils, meaning they are designed to perform well in a range of temperatures. The key difference lies in their viscosity at cold temperatures:
- 0W-20: The "0W" indicates that this oil flows more easily at very low temperatures, making it ideal for cold climates or winter conditions.
- 5W-20: The "5W" means this oil is slightly thicker in cold temperatures compared to 0W-20, but it still performs well in moderate climates.
At operating temperature, both oils have the same viscosity (20), meaning they provide similar protection for your engine under normal driving conditions.
When Is It Okay to Use 5W-20 Instead of 0W-20?
In some cases, using 5W-20 instead of 0W-20 is acceptable, but it depends on your vehicle and driving conditions:
- Manufacturer's Recommendation: Always check your vehicle's owner's manual. If the manufacturer specifies 0W-20, it's because the engine was designed to perform optimally with that oil.
- Climate Considerations: If you live in a warmer climate where temperatures rarely drop below freezing, the difference between 0W and 5W may not significantly impact your engine's performance.
- Temporary Use: If 0W-20 is unavailable and you need an oil change immediately, 5W-20 can be used as a temporary substitute. However, it's best to switch back to 0W-20 at your next oil change.
Potential Risks of Using 5W-20 Instead of 0W-20
While 5W-20 can work in some situations, there are potential risks to consider:
- Cold Weather Performance: In extremely cold temperatures, 5W-20 may not flow as easily as 0W-20, potentially leading to increased engine wear during startup.
- Warranty Concerns: If your vehicle is under warranty, using an oil grade other than what is specified in the manual could void the warranty.
- Fuel Efficiency: 0W-20 is often recommended for its fuel efficiency benefits. Using 5W-20 might slightly reduce your vehicle's fuel economy.
Conclusion
While 5W-20 can be used as a temporary substitute for 0W-20 in certain situations, it's always best to follow your vehicle manufacturer's recommendations. At Kevin's Autos, we recommend sticking to the specified oil grade to ensure optimal engine performance and longevity.

Frequently Asked Questions
What temperature is 5w20 oil good for?
PETROFLO 0w-20 and 5w-20 SYNTHETIC MOTOR OIL protects engines up to 204°C (400° F.).
Can I use 5W20 instead of 0W20 in hot weather?
The 5W-20 oil is the same except for a viscosity of 5 in cold temperatures. Both oils are designed to use in cold-weather regions. However, these multi-grade oils can perform in hot weather too, although not extremely hot.
What if I put 5W20 instead of 0W20?
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. Was this article helpful?
Why does Honda use 0W20 oil?
Almost 20 years ago, Idemitsu partnered with Honda to develop a lower viscosity oil to boost fuel economy in their hybrid vehicles. After rigorous testing and refinement, Honda began to fill their new Insight Hybrid at the factory with Idemitsu 0W-20.
Can I mix 5w20 synthetic with regular oil?
The short answer is yes. There is no danger or risk of combustion, and mixing the two types of oil won't harm your engine. However, it's important to note that if you do mix the two, the conventional oil can keep the synthetic from performing to its fullest potential.
Will thicker oil damage my engine?
Using a viscosity one grade higher or lower than what's recommended for your engine likely won't do lasting harm. But, to alleviate any concerns about engine protection and your vehicle warranty, it's best to use the viscosity recommended in your owner's manual.
Can I run 5W30 instead of 0W20?
Using the proper viscosity motor oil will help protect and maintain the performance of your vehicle's engine. Thus, always refer to the manufacturer's recommendation while your vehicle is under warranty. **if you have a car that recommends 0W-20, do not use 5W-30 – back # of vis-grade must match or it is a no-go.
Is 0W-20 good for summer?
0W-20, for example, is rated at 104°F (40°C) for external temperatures, and 212°F (100°C) for internal engine temperatures. So, the 0W rating of most oils, including ENEOS, is within operational parameters of warmer climates like Hawaii, Phoenix, and Las Vegas.
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.
Will the wrong oil damage my engine?
Potential Damage: While using the wrong oil may not cause immediate damage, it can lead to long-term problems such as increased engine wear, overheating, and ultimately, engine failure. It's crucial to use the type of oil recommended in your owner's manual to ensure optimal performance and longevity of your engine.
