Do You Really Need to Use Heavier Car Oil in Summer?

As a car owner, it’s important to take good care of your vehicle and give it the proper maintenance it needs to run smoothly. One of the questions that often comes up during the warmer months is whether or not it’s necessary to use heavier oil in the summer. In this blog post, we’ll explore the reasons why you might want to consider using a heavier oil during the summer months, and the factors that can help you determine what type of oil is best for your car when you go in for an engine oil change.

What is Oil Viscosity?

To understand why you might want to use a heavier oil in the summer, it’s important to first understand what oil viscosity is. Viscosity refers to the thickness or consistency of the oil, and it plays a critical role in how well the oil lubricates your engine. The thicker the oil, the more it can protect your engine from wear and tear.

Oil viscosity is rated using a numerical system developed by the Society of Automotive Engineers (SAE). This system uses a combination of letters and numbers to indicate the viscosity of the oil. The first number in the rating, followed by the letter “W” (which stands for “winter”), indicates the oil’s viscosity in cold temperatures. The second number indicates the oil’s viscosity at higher temperatures.

For example, if you see “10W-30” on a bottle of oil, that means the oil has a viscosity of 10 in cold temperatures and 30 in high temperatures. The higher the number, the thicker the oil.

Why use a heavier oil in the summer?

Now that we understand what oil viscosity is, let’s take a look at why you might want to consider using a heavier oil in the summer.

One reason is that higher temperatures can cause oil to thin out, which can reduce its ability to protect your engine. When oil thins out, it flows more easily, which means it can’t provide as much cushioning between the metal parts in your engine. This can lead to increased wear and tear on your engine over time.

Using a heavier oil in the summer can help compensate for this thinning effect. The thicker oil can help provide better lubrication and protection for your engine, which can help keep it running smoothly in the heat.

Factors to consider when choosing oil viscosity

While using a heavier oil in the summer can be beneficial for some cars, it’s important to remember that not all engines are created equal. The ideal oil viscosity for your car will depend on a variety of factors, including the make and model of your car, its age, and your driving habits.

Here are some factors to consider when choosing the right oil viscosity for your car during an engine oil change service:

1. Make and Model of Your Car: Some engines are designed to use a specific type of oil, so it’s important to consult your owner’s manual or talk to a mechanic to determine what viscosity is best for your particular car.

2. Age Of Your Car: Older cars may benefit from a heavier oil, as they tend to have more wear and tear on their engines. However, using too heavy of an oil can also cause problems, so it’s important to consult with a mechanic to determine what’s best for your car.

3. Your Driving Habits: If you frequently drive in stop-and-go traffic or haul heavy loads, you may want to consider using a heavier oil to provide extra protection for your engine.

4. The Climate Where You Live: If you live in a particularly hot or cold climate, you may need to adjust your oil viscosity accordingly. Hotter climates may benefit from a heavier oil in the summer, while colder climates may require a thinner oil in the winter.

It’s also important to note that oil alone is not enough to protect your engine in extreme temperatures. This is why most modern cars are equipped with a cooling system that helps regulate the engine temperature. In addition, regular maintenance, such as checking and replacing the air filter, can also help ensure your engine is running efficiently in all seasons. Of course, if you have any concerns about your car’sengine oil change and performance, it’s always a good idea to consult with a trusted mechanic.
