Car Engine Oil Uncovered: Know Your Vehicle’s Lifeline
The most essential thing that is used in car service is engine oil. Car Engine oil is one of the main lubricants that have a big part to play in the combustion cycle. It keeps the engine cool and makes sure that the piston rings in the IC engine are sealed properly. So, let’s have a look at all the things that this wonder liquid does to our car.
-
Provides Lubrication
The motor oil lessens the friction amongst the various components of the engine during the combustion cycle. By providing a thin layer of oil, parts of the engine do not rub each other harshly. This engine oil reduces the wear and tear.
-
Neutralizes Acids
During the process of combustion, fuel and as well as the oxidization of other lubricants produce acids. Engine oil is responsible for neutralizing these acids.
-
Cleans out Sludge
Engine oil plays an important role in making sure the engine block is clean and free from residue. If the engine sludge is not properly removed, this could lead to blockage.
-
Inhibits corrosion and oxidation
Another function of engine oil is preventing corrosion. Motor oil protects the cylinder blocks from rust.
So now we know that car engine oil is essential for the smooth running of the engine. But do you know all engines can’t work with the same engine oil?
Yes, different engines require different engine oils to function and operate normally. The car manufacturer recommends the engine oil based on the parameters of your car. You ought to know the grade of the engine oil your car needs as well. This will help you get the best performance from your motor. A good oil will also increase the lifespan of the engine.
Know This! 7 Questions You Should Ask About Your Car Engine Oil
What are car engine oil grades?
Engine oils have different grades. SAE has graded them based on their viscosities. Viscosity is the quantity expressing the internal friction of the fluid. Different engine oils have different viscosities at room temperature. They also react differently to temperature changes.
What does 20W-40 mean in car engine oil?
The engine oil grade is in the form of an alpha-numeric code. Let’s see what each character that makes up the code means:
- The first number is followed by a ‘W’. Here the W stands for Winter and represents how the oil will react to a cold start.
- In simple words, the number preceding W represents the parameter. Tells us how the oil will flow in cold conditions.
- The smaller the number, the better will be the flow. For instance, a 5W-30 oil will have a better cold flow than a 10W-30 engine oil.
- The number in the following part indicates how finely the oil will flow at normal operating temperature.
The 10W-30 engine oil will have a better flow than the 10W-40 engine oil at normal operating temperature.
Motor Oil Grades
Take a look at some internationally used engine oil grades-
- 0W-20 This engine oil is relatively thinner when you start the engine. Here in 0W-20, the viscosity of the oil is 0 when the motor is cold. When the engine reaches its normal operating temperature the viscosity of the oil becomes 20.
- 0W-30 The 0W-30 oil is engineered to behave as a 0-weight oil at the starting temperature and a 30-weight oil when the engine reaches its normal operating temperature.
- 0W-40 The 0W-40 oil is engineered to behave as a 0-weight oil at the starting temperature and a 40-weight oil when the engine reaches its normal operating temperature.
- 5W-30 5W-30 is the most commonly available and most extensively used engine oil in the Indian market. Most of the Indian car manufacturers recommend this.
- 5W-40 5W-40 is a fully synthetic engine oil that performs like a 5-weight engine oil when experiencing a cold start. It acts like a 40-weight oil once the engine reaches normal operating temperature.
- 10W-40 10W-40 is the engine oil that offers a 10-weight performance in the cold starting temperature. On the other hand, it provides a 40-weight performance at the normal operating temperature of the engine.
What are the types of car engine oils?
Before you go ahead and purchase any engine oil, know what type of oil your hatchback, sedan or SUV requires. It is essential to understand what goes into your car. This is after all the deciding factor that ensures that the engine runs smooth, slick, and efficient.
In general, there are three types of engine oil: Mineral, Semi-Synthetic, and Synthetic Engine Oils.
Mineral Engine Oil
This is the crudest kind of engine oil. Mineral Engine oil is considered the genesis that paved the way for modern car engine oils. Mineral oil is essentially refined petroleum oils which undergo treatment to function under a wide range of temperatures. Besides, mineral oil is cheaper in the market compared to the other two varieties. Nowadays, we use mineral oils in older vehicles and motorcycles.
The biggest problem with mineral oil is that it offers little to no lubrication and protection against friction-induced heat. Also, they perform very inefficiently in colder temperatures. They are also much more susceptible to breakdown during high-temperature uses. Mineral oil requires more frequent replacement as well. They don’t last for more than 5000 km.
Semi-Synthetic Engine Oil
Semi-Synthetic Oil | Engine Oil
This positions itself right in between the territory of Mineral and Full Synthetic oil. Semi-synthetic oil offers the affordability of minerals and the performance of synthetic. This kind of engine oil provides as much as three times the protection compared to mineral oils.
Semi-synthetic oil is also known as synthetic blend oil. Here, a small amount of synthetic engine oil is mixed in with mineral oil. This boosts its properties without escalating the cost by much. The addition of synthetic oil enhances the viscosity and wear resistance of the engine oil at higher temperatures and stress. Synthetic-blend engine oils can also offer better performance at lower temperatures compared to mineral oils.
The thumbs down with semi-synthetic is that they do not offer the superior level of protection that a full synthetic does.
Full Synthetic Engine Oil
Fully synthetic engine oil
This is the cutting edge in engine oil technology. Full synthetic engine oil delivers excellent protection and contributes to greater fuel efficiency.
Synthetic oils go through extensive treatment in the laboratory. The process breaks down the mineral oil into the most basic molecules. This makes them significantly superior to their counterparts. This also helps remove any impurities to a very high degree. The molecules of synthetic oil are also very consistent in their size and shape, offering superior lubrication. Full synthetic oil functions at their optimum in both low or high temperatures, or under extraordinary stress.
The science behind manufacturing synthetic engine oil is an expensive and painstaking one, which makes synthetic oils significantly costly.
Your guide to choosing the right kind of engine oil for your car
Motor oil is indispensable to your car engine. It makes sure that the motor works in the best condition possible. So which car engine oil should you go for? This would depend on the car you drive as well as where you drive it. However, remember to choose the manufacturer-specified engine oil for your car.
