This article explains the difference between 10W-30 and 10W-40, which deals with a viscosity at high temperatures and low temperatures.
Talking about engine oil, it is one of the most important accessories, which is very important for a motorcycle today. Also, it is very important to choose a good motor oil on a technical basis, which affects our engine and our bike. Today we will talk about engine oil in this article.
If we see in today’s society, engine oil of many types, many grades, or say, many companies’ engine oil is available in the market, it is absolutely impossible to tell in this society which engine oil is better for our motorcycles.
While selecting the engine oil of a motorcycle, one also has to pay attention to how its viscosity is classified. And we can see this stickiness on the bottle of engine oil and guess whether it is better for our engine.
In this article, we will clear up the confusion about numbers related to viscosity. What is the relation between these numbers and our engine oil? Practically, in this article, we will see which is better, 10w30 or 10v40.
After all, what do all these numbers mean1!!
A grade is given by each engine oil that tells how this grade will work in cold temperatures or hot temperatures.
Here we talked about cold temperatures and hot temperatures! In fact, the flow of oil changes in cold temperatures and in hot temperatures. In cold temperatures, the oil starts to solidify and it becomes viscous. And vice versa, in hot temperatures. Due to hot temperatures, the shedding of oil starts increasing and it starts flowing faster. The numbers written on the back of the engine oil indicate this quality.
Here in 10w30 or 10v40, what does “10” mean?
Here, “10” is the cold weather viscosity rating. The number represents the ability of the oil to maintain resistance to hardening and thickening at a temperature of 0 °C. This is very important for the engine.
The Letter “W” Mean?
The “W” on it denotes Winter. It tells what the viscosity rating will be at cold temperatures.
The Last Number “30” or “40” Mean?
This is the grade given by SAE that tells what the final number is the hot or operating temperature rating. Conversely, how resistant is the oil to being diluted at 100°C when the temperature is hot?
Now, we can infer many things from this. If we compare 10w30 or 10v40, 10W-30 will be thinner at higher temperatures than 10W-40, as opposed to being slightly thinner at higher temperatures. There is a significant difference between these two, which we shall see later.
Why should only 10W-30 be used as engine oil?
Here we are going to compare. Then we will see that the viscosity of 10W-30 will work, which we have seen very well before. This is the specialty of thin oil, that it maintains its thickness even at normal temperatures.
Gives better fuel economy-It helps the engine to work and run more efficiently because the fuel is settled and the money is also saved, which is also economical as there is friction in the engine. Its main function is to increase the efficiency of the engine.
Better at low temperatures – Depending on the temperature, 10W-30 is significantly better than 10W-40, but at operating temperature, the environment remains as warm as it was outside the vehicle.
Even better for every day or racing-if, we see that it is not suitable for every day or racing or will not work in high temperatures, then it is much better to use because of its fine-tuning with turbocharged. Really thick oil is hard to push in there with a normal engine, so it is better for a normal vehicle.
Why should only 10W-40 be used as engine oil?
10W-40 is the complete opposite of 10W-30, which has a higher viscosity and is thicker enough to be used easily in hot places.
Practically Suitable for Hot Temperatures: This grade is primarily designed for hot temperatures as it has a longer shelf life. The oil should not be too thin, due to which the lubrication of the oil remains with the engine, the oil sticks to the engine for a long time.
Suitable for Old or Retained Vehicles: Actually, old vehicles are very worn and have not had any kind of operation in a long time, so they need lubrication as well as oil thickness so that the machine or engine can run again.
According to milage – If you talk about it here, 10W-40 will give more than 10W-30 because it has more thickness, as well as its viscosity, is more than is needed.
Here we have seen the difference between both 10W-30 and 10W-40. Both the grades are important according to their needs, as one is important at cold temperatures and some at warm temperatures.
