Misconceptions About Engine Oil – Everything You Need To Know!
Published by: Chevron Technology | 21-Jan-2025
Engine oil, or motor oil, plays a significant role in keeping the smooth functioning of engine parts through lubrication and reducing friction. The importance of using the best engine oil can’t be neglected, as it protects the car engine parts from rust, allowing them to move smoothly. However, there are certain myths about engine oil that are not true.
In this guide, we will be debunking myths about engine oil, and helping you choose the best motor oil for your car!
ENGINE OIL MYTHS
Car maintenance and enhanced performance depend heavily on the type of motor oil used. If the correct oil type is not used, it will affect the performance of the engine. Not only that, but engine oil also reduces wear and tear of parts, minimizes friction, cools the engine, and prevents engine seizing.
The myths about engine oil can affect the performance of your car and can cost you extra money for maintenance. Therefore, it is essential to understand the misconceptions about engine oil that might have once been considered true but are now invalidated.
Below are some of the myths about engine oil:
CHANGE THE OIL AS SOON AS IT GETS DARK
The dark engine oil is not always dirty; it can get dark due to its cleaning action. This is one of the most common myths about engine oil. The dark colour is not necessarily an indication of dirty oil requiring a change. Engine oil becomes dark when the additives start working to clean the engine components. Therefore, the dark colour of motor oil is never a sign that you need to replace it immediately. However, grainy or gritty oil does require a quick change.
CHANGE THE ENGINE OIL AFTER EVERY 5000 KILOMETRES
This is another myth about engine oil. The truth is, with advancements in engine oils in India and globally, high-quality oils can last 10,000 to 20,000 kilometres, or even longer, depending on the product. Always refer to your vehicle’s user manual to determine the recommended oil change interval. The best engine oil for your car may last much longer than 5000 kilometers, but delaying oil changes will negatively impact engine performance.
ADDITIVES IN THE ENGINE OIL ARE ALL THE SAME
This myth suggests that all oil additives are similar, but that's far from the truth. Engine oil contains different additives for different purposes, such as cleaning, improving the viscosity index, and preventing rust and corrosion. Always refer to your car manual to see if any additional oil additives are required, as they can significantly impact your car’s performance.
SYNTHETIC ENGINE OIL CAUSES LEAKS
In the early years, synthetic oils didn’t suit the gaskets and seals, which caused oil leaks. However, this is now an outdated myth. Modern fully synthetic car oils have been reformulated by manufacturers, so leakage no longer occurs in vehicles that use them. While older cars (manufactured 15 years ago or more) may still experience issues with seal shrinkage, modern vehicles equipped with advanced materials will not leak when using synthetic engine oil for cars.
SWITCHING ENGINE OIL BRANDS IS HARMFUL TO THE ENGINE
Many people believe that switching motor oil brands will damage their engines, but this is a myth. As long as the specifications match those required by your vehicle, switching brands won’t harm your engine. The type and quality of oil matter far more than the brand.
ENGINE OIL IS THE SAME IN ALL BRANDS
This is another misconception. Engine oil differs across brands due to variations in base oils and additives used. Therefore, it’s essential to select the best engine oil for your car by considering the specific formulations that meet your vehicle’s needs. Caltex Lubricants offers high-quality oils suited to different engine requirements.
THICKER ENGINE OIL IS GOOD FOR YOUR CAR
This is yet another engine oil myth. The viscosity of the oil should always be based on your vehicle’s specifications and engine conditions. Using oil that is too thick can negatively impact engine performance, particularly in modern cars that require lighter oils. Always refer to your car manual to find the oil type and viscosity that best suits your engine's needs.
By knowing these facts, you can make informed decisions about motor oil and engine oil for your car, ensuring better performance and longevity. Don't let myths about engine oils in India lead to unnecessary costs and maintenance issues. Stay informed, and choose wisely!
