What happens if I put 5W-30 instead of 5W20?
Choosing the right motor oil for your vehicle is crucial for maintaining its performance and longevity. However, mistakes can happen, and you might find yourself wondering what would occur if you used 5W-30 oil instead of the recommended 5W-20. As an experienced auto service provider, I’ll break down the potential effects of this substitution and what you should do if it happens.
Understanding the Difference Between 5W-20 and 5W-30
Both 5W-20 and 5W-30 are multi-grade oils, meaning they perform well in a range of temperatures. The numbers in their names refer to their viscosity, or thickness, at different temperatures:
- 5W: Indicates the oil's viscosity in cold temperatures. Both 5W-20 and 5W-30 perform similarly in cold weather, ensuring easy engine starts and proper lubrication.
- 20 vs. 30: Refers to the oil's viscosity at operating temperature. 5W-20 is thinner than 5W-30 when the engine is hot, which can impact how the oil flows and protects engine components.
What Happens If You Use 5W-30 Instead of 5W-20?
Using 5W-30 instead of 5W-20 may not cause immediate damage, but it can have some long-term effects on your engine's performance and efficiency. Here’s what you need to know:
- Reduced Fuel Efficiency: 5W-30 is thicker at operating temperatures, which can increase resistance within the engine. This may lead to slightly reduced fuel efficiency compared to 5W-20.
- Potential Engine Wear: Some engines are specifically designed to use thinner oil like 5W-20 for optimal lubrication. Using a thicker oil could result in less effective lubrication, especially in tight engine tolerances, potentially leading to increased wear over time.
- Warranty Concerns: If your vehicle is under warranty, using an oil grade other than what is recommended in the owner’s manual could void the warranty in some cases.
When Is It Okay to Use 5W-30?
There are situations where using 5W-30 might be acceptable or even beneficial:
- High Temperatures: If you live in a region with extremely high temperatures, 5W-30’s thicker viscosity can provide better protection against heat-related wear.
- Older Engines: For older vehicles with higher mileage, 5W-30 can help reduce oil consumption and provide better sealing in worn engine components.
What Should You Do If You’ve Used 5W-30 by Mistake?
If you’ve accidentally used 5W-30 instead of 5W-20, don’t panic. Here’s what you can do:
- Check Your Owner’s Manual: Some vehicles allow for a range of oil viscosities depending on driving conditions. Your manual will clarify if 5W-30 is acceptable.
- Monitor Your Engine: Pay attention to any unusual noises, reduced performance, or warning lights. If you notice anything unusual, consult a professional mechanic.
- Consider an Oil Change: If you’re concerned about long-term effects, schedule an oil change to replace the 5W-30 with the recommended 5W-20.
Conclusion
While using 5W-30 instead of 5W-20 is unlikely to cause immediate harm, it’s always best to stick to the manufacturer’s recommendations for optimal engine performance and longevity.

Frequently Asked Questions
Will it hurt my car if I use 10W30 instead of 5w20?
It will result in poor engine performance since it will be unable to adequately lubricate your car's parts. This might cause your car to wear down faster, resulting in pricey repairs. Furthermore, using the wrong type of oil can damage components such as seals and gaskets, increasing maintenance expenses.
Can I mix 0,20 and 5:30?
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.
Does it hurt an engine to go from synthetic to regular oil?
Yes! Switching from synthetic oil to conventional (and back again) won't cause any harm to your engine.
What is the difference between 5W30 and 5W20?
Ultimately, choosing the right viscosity is a balancing act between competing priorities. Let's look at 5W-20 vs 5W-30 again. The 5W-20 will remain a little thinner at operating temperature, as indicated by its lower “20” number, while 5W-30 will provide a slightly thicker lubricating film.
Is it okay to use 5W30 instead of 5W20 on Reddit?
That said, running 5w30 in an engine that calls for 5w20 isn't really going to hurt anything, but you might notice a small drop in fuel economy.
What is a good substitute for 5w20 oil?
Therefore, a 0W would flow more easily than a 5W and could be an acceptable substitute. Thus, it is suitable to use a SAE 0W-20 as a replacement for SAE 5W-20 application.
Will it hurt my car if I use 5W30 instead of 5W20?
It won't cause any problems. 5w30 is thicker than 5w20 in operating temperatures, but that doesn't mean there will be less oil flow. Oil pump will still pump the oil through the engine, and if thicker oil causes an increase in oil pressure, the oil pump will just bypass some of the oil back into the sump.
Can I mix 5W30 with 5W20?
Mixing 5W20 oil with 5W30 oil is not recommended, as it can cause several problems for your engine. The main reason is that 5W20 and 5W30 have different viscosity ratings, which means they have different thickness and flow characteristics at different temperatures.
Will the wrong oil damage my engine?
Choosing the wrong type of oil might have serious repercussions. The wrong type of oil might be either too thick or too thin for the engine, which can harm moving elements like bearings and pistons. In extreme situations, this may lead to engine failure as well as lower performance and increased wear and tear.
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.
