Can you run 5W30 instead of 5w20?
As a car owner, you might find yourself wondering whether you can use 5W30 motor oil instead of 5W20 in your vehicle. This is a common question, especially when you're in a pinch or trying to make sense of the differences between these two oil types. At Kevin's Autos, with years of experience in car maintenance and repair, we’re here to help you understand the implications of this choice and guide you toward the best decision for your vehicle.
Understanding the Difference Between 5W30 and 5W20
The numbers and letters in motor oil grades, such as 5W30 and 5W20, represent the oil's viscosity and performance in different temperatures. Here's a quick breakdown:
- 5W: The "5W" indicates the oil's viscosity in cold temperatures. Both 5W30 and 5W20 perform similarly in cold weather, ensuring your engine starts smoothly in winter.
- 20 vs. 30: The second number (20 or 30) represents the oil's viscosity at operating temperature. 5W20 is thinner at high temperatures compared to 5W30, which is slightly thicker and provides more resistance to heat.
In essence, 5W30 offers better protection in high-temperature conditions, while 5W20 is designed for better fuel efficiency and smoother operation in engines that require lower viscosity oil.
Can You Use 5W30 Instead of 5W20?
The short answer is: it depends on your vehicle's manufacturer specifications. Here’s why:
- Manufacturer Recommendations: Most car manufacturers specify the type of oil that works best for their engines. This information can be found in your vehicle's owner’s manual. If your car is designed for 5W20, using 5W30 might not provide the optimal performance or fuel efficiency.
- Engine Design: Modern engines are built with precise tolerances, and the recommended oil viscosity ensures proper lubrication. Using a thicker oil like 5W30 in an engine designed for 5W20 could lead to increased friction and reduced efficiency.
- Warranty Concerns: If your car is under warranty, using an oil grade other than the one specified could void the warranty in some cases. Always check with your manufacturer or dealership before making a switch.
When Is It Okay to Use 5W30?
There are certain situations where using 5W30 instead of 5W20 might be acceptable:
- High Temperatures: If you live in an area with extremely high temperatures, 5W30 might provide better protection against heat-related wear and tear.
- Older Engines: For older vehicles with higher mileage, a slightly thicker oil like 5W30 can help reduce oil consumption and improve engine performance.
- Emergency Situations: If 5W20 is unavailable and you need to top off your oil, using 5W30 temporarily is better than running your engine with low oil levels.
Final Thoughts
While 5W30 and 5W20 are similar in many ways, it’s crucial to follow your vehicle manufacturer’s recommendations to ensure optimal performance and longevity.

Frequently Asked Questions
What can I substitute 5w20 with?
You can easily substitute 5w20 with 0w20, just like M1 says. According to them, you'll still have warranty protection. All the 0 means is it can start easier in the cold then 5w.
Is it OK to use thicker oil in high mileage engine?
Using a thicker oil or one with a higher viscosity may also be helpful once your car reaches 100,000 miles. Or you can opt for oil additives that help stop leaks.
Can you put 5W30 in a 5w20 engine in emergency?
In an emergency, you may have to substitute one for the other, but it's always best to follow your manufacturer's recommendations.
Can I use 5W-30 instead of 5w20 in my Hyundai?
Either one will work. Some like a little thicker oil with higher mileage as tolerances have gotten larger.
Can I use 5w30 instead of 5w20 for 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.
What will happen if I put 5w30 instead of 5w20?
The problem is that while 5w20 to 5w30 is not a huge difference, when 30 weight is the boundary for the particular engine, going thinner causes damage. It's just like going thicker in subzero temps when the engine isn't designed for it causes damage.
Can you mix 5W30 and 5w20?
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 5w30 instead of 5w20 in my Ford Edge?
You'll be fine. Don't worry about the difference between 5w20 and 5w30. I accidentally put 5W-30 oil in my car when it takes 5W-20.
