What happens if I put 5w20 instead of 5w30 in my car?
Choosing the right engine oil for your vehicle is crucial for maintaining optimal performance and longevity. Many car owners may wonder what the implications are of using a different oil viscosity than recommended. In this article, we will explore the differences between 5W20 and 5W30 motor oils and what could happen if you mistakenly use one instead of the other.
Understanding Oil Viscosity
Motor oil is classified by its viscosity, which indicates how easily it flows at different temperatures. The numbers in the oil designation (like 5W20 or 5W30) represent the oil's viscosity rating. The "5W" indicates the oil's viscosity at low temperatures (the "W" stands for winter), while the second number indicates its viscosity at high temperatures.
Key Differences Between 5W20 and 5W30
- Viscosity at Operating Temperature: 5W30 is thicker than 5W20 when the engine is at operating temperature. This means that 5W30 provides a better film strength, which can be beneficial for engine protection.
- Fuel Economy: 5W20 is often recommended for newer engines designed for better fuel efficiency. It can help improve fuel economy due to its lower viscosity.
- Engine Wear Protection: The thicker 5W30 may offer better protection against wear and tear, especially in high-stress conditions or older engines.
Potential Consequences of Using 5W20 Instead of 5W30
If you accidentally use 5W20 in an engine that requires 5W30, several outcomes may occur:
- Increased Engine Wear: The thinner oil may not provide adequate protection, leading to increased wear on engine components over time.
- Higher Operating Temperatures: The engine may run hotter due to reduced oil film strength, which can lead to overheating and potential damage.
- Oil Consumption: Thinner oil may be consumed more quickly, requiring more frequent top-ups.
What Should You Do?
If you realize you've used 5W20 instead of 5W30, it's advisable to change the oil back to the recommended viscosity as soon as possible. Regular oil changes are essential for maintaining engine health, and using the correct oil type is a key part of that process.
In conclusion, while using 5W20 in place of 5W30 may not cause immediate catastrophic damage, it can lead to long-term issues that affect your vehicle's performance and lifespan. Always refer to your owner's manual for the manufacturer's recommendations on oil viscosity to ensure your engine runs smoothly.
Frequently Asked Questions
Is 5W-20 good for high mileage?
MAG 1® High Mileage Synthetic Blend 5W-20 Motor Oil is formulated to extend engine life for vehicles that have already exceeded 75,000 miles. It seals leaks, features superior oxidation stability, and provides extra protection against sludge, deposit buildup, and high temperatures.
Can I use 5W30 instead of 5W20 for a 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.
Is thicker oil better for high mileage cars?
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.
What happens if you put the wrong oil in the car?
The wrong engine oil can decrease your vehicle's performance and cause engine damage. The cost of purchasing the recommended oil is far less than rebuilding an engine. Always consult your owner's manual to find the right engine oil for your vehicle.
Is 5W20 better than 5W30 in hot weather?
Because a 5W-20 is more susceptible to breaking at high running temperatures, the 5W-30 option often delivers better performance in certain applications. Many vehicle owners in warmer climates prefer 5W-30 since it retains its viscosity in hotter temperatures.
Can you use ow 20 in place of 5W-30?
0W motor oils (0W-20) are suitable for use in 5W applications because the 20 refer to the viscosity measurement value.
Can I mix 5W20 and 5W30?
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.
Is it OK to use thicker oil in high mileage engine?
Consequently, many mechanical specialists suggest adding a thicker engine oil to high mileage engines as thicker oils are always less likely to result in leakage. Additionally, motorists can also counter this issue by using an engine oil that has been enhanced with anti-leak additives to mitigate this problem.
What temperature is 5W-20 good for?
* This technologically advanced motor oil formulation provides 10X** better internal engine heat protection than industry standards (up to 500 degrees Fahrenheit), as well as exceptional low-temperature protection (to -30 degrees Fahrenheit)—bringing quick cold-weather starting and ultra-fast protection to your engine.
What happens if I use 5W20 oil instead of 5W30?
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.
