It will not be wrong to say that engine is the heart of any vehicle. If you own any car or even a motorbike, you must always be worried about selecting the most efficient and high-quality engine oil so that your car gives you a perfect and smooth ride.

We assure you that you’re going to get incredible information in this article. Also, if you are confused about different brand oils and their grades, then you have just hit the right spot. And after each section, your queries will be vanished for sure. So without any further delay, let’s get into it and explore the most amazing engine oil for your car.

What are Engine Oils and their grades?

Engine oil is referred to as any lubricant that lubricates the internal parts of the engine. There are different components and interior parts that keep on moving when a car is moving on the road. As a result, there is a lot of friction produced along with heat energy. In this regard, engine oil acts as a lubricant and removes all the dust and heat, and avoids corrosion in the parts of the engine.

Engine oil removes all the heat away from the engine parts by circulating throughout the engine and gives the cooling effect. Now, you must be very clear about the function of engine oil. Let us now move to the next part of our question. What are the grades that we see on different engine oil brands? Well, these grades, or commonly, numbers, describe the viscosity of the engine oil. Another word for viscosity is any liquid’s thickness. The grade that people see on the bottles of engine oil describes the measurement, which is based on the flow time of engine oil. Every different grade of oil performs differently in different temperature conditions. Definitely, we will discuss this aspect in detail in our upcoming subsection of this article.

What do “W” and numerics indicate in engine oil Grade?

You might encounter different grades on different engine oil brands, such as 0W-20, 5W-30, 5W-40, 5W-50, and many others. But do you know what ‘’W’’ indicate in this engine oil grade? No worries at all because we will explain this in detail. The first number before ‘’W’’ indicates engine oil performance in cold temperatures. According to a general phenomenon, when the temperature drops, oil becomes thick, and automatically, it will be difficult to reach every part of the car engine. And “W” goes for winter.

Hence we can say that the first number must be as small as possible in freezing temperature conditions. For example, 0W-40 will be more efficient than 5W-40 in below 0 degrees Fahrenheit. Another disadvantage of using thick oils in Winter is it will cause a hole in the filter, So the oil will not be cleaned properly. The final result will be ultimately damaging to your engine and it may also cause complete failure as well. So it is always suggested to use, accurate winter rating engine oils in cold temperatures.

Now here comes the last digit that comes after the dash. It indicates the thickness of oil in high temperatures. When the engine is working, it bears stress, and a lot of heat energy is released. If the environmental conditions are combined with it, it will cause thinning of oil, ultimately preventing it from cleaning the engine properly. At this point, engine oils with higher viscosity are needed to maintain performance and improve gas mileage.

Hence, it is very clear that there are different internal grades for different temperature conditions, for example, engine oils that are suitable and give good performance in tropical regions cannot go well for vehicles in temperate regions of the world.
