![]() There are different types of oil grades used in engines. Let’s find out about the engine oil grades: UNDERSTANDING ENGINE OIL GRADES This was all about different car engine oil types. Optimises the fuel efficiency as it provides better performance at 5W-30 grade than the 5W-20 grade of synthetic oil.Protects the engine exhaust equipment from harmful chemicals.Maximises the life of engine by reducing wear and tear.The high performance oil provides the following advantages to the vehicle engine: This is one of the car engine oil types enhanced with extra high performance additives. High performance motor oil is commonly used in sports and racing cars. It is more cost-effective than the fully synthetic oil.Better engine performance than mineral oil because of the low viscosity.However, fuel economy can become an issue if you keep using semi-synthetic oil instead of fully-synthetic one, but there are also the following advantages of semi-synthetic oil: Semi-synthetic engine oil provides better performance in low and high temperature conditions because of its mixture. This type of car engine oil is a mixture of mineral and synthetic oil. SEMI-SYNTHETIC OIL The semi-synthetic engine oil is a mixture of mineral and synthetic oils to enhance viscosity index and performance Moreover, it is less affected by the temperature change, for instance, in high temperatures its flow and viscosity is retained and in low temperatures, it doesn’t become thick and provides a better flow. Synthetic oil has a low viscosity that gives it a better flow. Performs better than the mineral base oils in extreme temperature conditions.More reliable for modern vehicle engines.Five times better cleansing than the mineral one.The synthetic engine oil type provides the following advantages: Moreover, the reduction process in synthetic oils is better than the mineral base oils due to the addition of chemicals such as antioxidants. This type of engine oil provides a better flow on ignition start-up where most of the wear and tear of parts occur. Synthetic oil is one of the finest car engine oil types. The natural oils are enhanced with additives to provide better performance. SYNTHETIC OIL The synthetic engine oils provide a better cleaning, engine performance and fuel efficiency than the mineral ones However, mineral oil is the least expensive of all the car engine oil types. This type of engine oil is not compatible with extreme temperature conditions because of no artificial additives in it. The mineral oil is prepared from crude oil and used in older engines. There are mainly four different types of engine oil with different viscosity and quality levels. Therefore, this guide will help you with choosing the right engine oil type so you can always enjoy a smooth drive with a good engine performance. Using the wrong engine oil can cause various effects in engine performance, oil leakage and fuel efficiency. Protects the engine components from rust and corrosion.Neutralises acids produced during combustion.Reduces the friction, so that all parts move smoothly.Cleaning the contaminants from the engine to enhance the performance.IMPORTANCE OF ENGINE OILĮngine oil has multiple advantages as it helps in the following functions: In this guide, we will discover different car engine oil types and grades that will help you choose the right one for your vehicle. Moreover, there are different types of oil grades for your engine to run smoothly. According to the engine type and conditions, car owners can use different car engine oil types. See below a chart demonstrating some example oil grades and outside temperature ranges.Engine oil is one of the most essential requirements for the proper functioning of the vehicle. ![]() Straight SAE 30 oil is often used for smaller cooled engines in lawnmowers, garden tractors and portable generators. ![]() Monograde oils such as SAE 30, 40 and 50 are no longer used in the latest automotive engines but may still be required for us in vintage or classic engines. Įxample – a good way to remember how oil reacts to temperature is by imagining you’re adding cooking oil in to a frying pan – at first, when the oil hasn’t had a chance to heat up it starts out quite thick but once the pan gets hotter, the oil becomes thinner and more runny. ![]() This demonstrates the oils resistance to thinning at high temperatures. The second number after the W represents the oils viscosity measured at 100 degrees Celsius. So, a 5W-30 would thicken less than a 10W-30 but more than 0W-30. The number before the W represents the viscosity (thickness)and rates the oil’s flow at -17.8 degrees Celsius. The W stands for WINTER, this is commonly mistaken by many who consider this to stand for Weight.
