Nowadays, we use mineral oils in older vehicles and motorcycles. Besides, mineral oil is cheaper in the market compared to the other two varieties. Mineral oil is essentially refined petroleum oils which undergo treatment to function under a wide range of temperatures. Mineral Engine oil is considered as the genesis that paved the way for modern engine oils. In general, there are three types of engine oil: Mineral, Semi-Synthetic and Synthetic Engine Oils. This is after all the deciding factor that ensures that the engine runs smooth, slick and efficient. It is essential to understand what goes into your car. On the other hand, it provides a 40 weight performance at the normal operating temperature of the engine.īefore you go ahead and purchase any engine oil, know what type of oil your hatchback, sedan or SUV requires. 10W-40 10W-40 is the engine oil which offers a 10 weight performance in the cold starting temperature.It acts like a 40 weight oil once the engine reaches normal operating temperature. 5W-40 5W-40 is the fully synthetic engine oil which performs like a 5 weight engine oil when experiencing a cold start.Most of the Indian car manufacturers recommend this. 5 W-30 5W-30 is the most commonly available and most extensively used engine oil in the Indian market.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 will reach its normal operating temperature.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.When the engine reaches its normal operating temperature the viscosity of the oil becomes 20. Here in 0W-20, the viscosity of the oil is 0 when the motor is cold. 0W-20 This engine oil is relatively thinner when you start the engine.Take a look at some internationally used engine oil grades. The 10W-30 engine oil will have a better flow than the 10W-40 engine oil at normal operating temperature. The number in the following part indicates how the finely the oil will flow at normal operating temperature.For instance, a 5W-30 oil will have a better cold flow than 10W-30 engine oil. The smaller the number, the better will be the flow.Tells us how the oil will flow in cold conditions. In simple words, the number preceding W represents the parameter.Here the W stands for Winter and represents how the oil will react to a cold start. The first number is followed by a ‘W’.
Motor oil grades explained code#
Let’s see what each character that makes up the code means: The engine oil grade is in the form of an alpha-numeric code. SAE (Society of Automotive Engineers) specified the scale for grading engine oil What does 20W-40 mean in engine oil? They also react differently to temperature changes. Different engine oils have different viscosities at room temperature. Viscosity is the quantity expressing the internal friction of the fluid. SAE has graded them based on their viscosities. Know This! 7 Questions You Should Ask About Your Car Engine Oil What are engine oil grades?Įngine oils have got different grades. A good oil will also increase the lifespan of the engine. This will help you get the best performance from your motor. You ought to know the grade of the engine oil your car needs as well. The car manufacturer recommends the engine oil based on the parameters of your car.
Yes, different engines require different engine oils to function and operate normally. But do you know all engines can’t work with the same engine oil? So now we know that the engine oil is essential for the smooth running of the engine. Motor oil protects the cylinder blocks from rust. If the engine sludge is not properly removed, this could lead to blockage.Īnother function of engine oil is preventing corrosion.

Engine oil is responsible for neutralising these acids.Įngine oil plays an important role in making sure the engine block is clean and free from residue. Thus engine oil reduces the wear and tear.ĭuring the process of combustion, fuel and as well as the oxidization of other lubricants produce acids. By providing a thin layer of oil, parts of the engine do not rub each other harshly. The motor oil lessens the friction amongst the various components of the engine during the combustion cycle.

It keeps the engine cool and makes sure that the piston rings in the IC engine are sealed properly. Engine oil is one of the main lubricants that have a big part to play in the combustion cycle. The most essential thing that is used in car service is engine oil.
