Motor oil is an integral part of any vehicle engine, providing vital lubrication to the engine’s moving parts. Choosing the right type of motor oil for your car is critical in order to maintain a smooth and efficient operation.
One of the frequent questions from car owners is whether to use 5w20 instead of 5w30, as both types are available in automotive shops. This article will provide an overview of the differences between these two varieties of motor oil, allowing you to make an educated decision on which one best suits your needs.
The most common multi-grade lubricants available in local auto parts stores are 5w20 and 5w30. These engine oils can alter their viscosity depending on the temperature, yet they possess different viscosities from one another. Those considering replacing a 5w30 with a 5w20 may find answers to their questions in an article devoted entirely to this topic.
Can 5w20 Be Used Instead Of 5w30?
Using the wrong oil in a vehicle can cause costly engine damage. For this reason, it is not recommended to use 5w20 instead of 5w30 engine oil because both have different viscosities. 5w20 oil is thinner and designed for newer engines while older models (1995-2003) should be changed with 5w30 oil. Using the thin variety of motor oil may not provide adequate protection for an aging engine, potentially leading to costly repairs or even reducing your warranty coverage. As such, it is important to pay attention to which type of motor oil you are using and that it complies with your car’s manufacturer instructions.
What Happens If 5W-20 Is Used Instead of 5W-30?
One of the most important things to consider when deciding whether to use 5w20 instead of 5w30 is your car model. Consulting the owner’s manual which generally comes with a chart that has a list of acceptable weights according to temperature, is key in determining what type of oil is best for your vehicle.
For new generation cars, it is recommended by manufacturers to use specific motor oil as this can provide an increase in fuel economy and reduce engine wear and higher engine temps. If you do accidentally put 5w20 into the wrong car engine, then no exceptional harm will occur.
However, if you are looking for improved fuel efficiency due to easier pumping thinner oil then check your owner’s manual prior as this should have a viscosity range that is acceptable. You may also find that both oils work well without hurting your vehicle engine under normal driving conditions such as temperatures below 120F or -30F cold.
As a result, although it is not recommended to replace 5w30 with 5w20, be sure to revert back to the recommended engine oil at every regular service change.
What Is The Difference Between 5W-20 And 5W-30 Oil?
Viscosity Index
The key difference between 5W20 and 5W30 motor oil lies in its viscosity. Viscosity refers to a liquid’s resistance to flow, with the number indicating how thick it is. The lower viscosity means that 5W20 flows more easily than its counterpart, which makes it ideal for engine startups during cold winter climates as it circulates quickly through bearings.
On the other hand, the second digit of “30” indicates that at higher temperatures, 5w30 acts as if it were heavier weight oil – thicker than when compared at colder temperatures. This can help ensure optimal lubrication within an engine even when exposed to extreme heat conditions due to prolonged use or a particularly hot climate.
Cold Temperature
The 5w20 engine oil type is a less viscous option compared to 5w30. This provides an advantage in colder climates, as the fluid flows smoothly and quickly through deeper engine components, lubricating them efficiently with less friction which enables faster starting of the vehicle engine.
On the other hand, The 5w30 works better in hotter climates due to its ability to retain viscosity even when exposed to heat. This ensures better protection for engine parts than that provided by the5w20 in normal temperatures. Furthermore, it prevents thinning of the oil too quickly due to higher temperatures which could lead to damage or malfunctioning of delicate parts within the motor.
Fuel Efficiency
The difference between 5w20 and 5w30 motor oil is evident in terms of fuel efficiency. Although both oils serve the same purpose, 5w20 motor oil is specifically designed to provide improved fuel efficiency when compared to its counterpart. This can be attributed to the fact that it has a thinner consistency; creating less resistance within the engine which ultimately results in better gas mileage.
Which One Is Economy
The 5w20 oil is considered to be more economical and offers better performance in colder climates compared to the 5w30. This is because the thinner consistency of the 5w20 reduces friction between engine components such as pistons and crankshafts, resulting in increased fuel economy. Despite this, however, 5w30 remains the most popular option due to its ability to provide excellent protection for a variety of engine types.
Is It Possible To Mix 5w20 and 5w30?
Mixing 5w20 with 5w30 engine oil is a safe practice, as both provide the same performance in cooler temperatures. Blending them together will not cause any technical issues provided that they are from the same API class. The oils have different additives and weight ratings, but this will not affect their compatibility when mixed together. Therefore, it is recommended to use a brand of the same API class for optimal results.
Final Thoughts
When it comes to choosing the right engine oil, it is important to consider the climate you live in. 5W20 and 5W30 are two flexible synthetic engine oils that can provide effective protection for your vehicle’s engine regardless of its location. In colder climates, 5W20 may provide more protection than 5W30 while in hotter temperatures, it is recommended to use 5W30 instead. As they offer similar levels of performance, someone might opt for using one over the other.
It is always best practice to check with a car manual before changing any parts or using a different type of engine oil as manufacturers often prefer certain types for specific models or years. If a model allows for either type of oil then following these guidelines should help you make an informed decision about which one would be better suited for your particular environment and situation.
