It will not be wrong to say that engine oil is the lifeline of a vehicle. It protects your car components from wear and tears even when the inside temperature does not cross beyond 120 degrees. Therefore, it is highly important to choose the right grade and quality of engine oil in order to protect your car engine from heavy damages.
Wrong fuel causes friction to increase instead of reducing the chance of occurrence or preventing it at all. As a result, the components in your car suffer heavy damages. What if you choose the wrong viscosity? It causes performance to drop significantly. In case of oil leakage or any technical issue, you must know how to fix the problem and if you are not aware of any technical issue, the engine will eventually seize and the cost of repairs will roll into a fortune.
Therefore, it is imperative to make an intelligent choice when buying engine oil for your best-used car in Kolkata.
How to Choose the Right Engine Oil?
Before you buy the engine oil, it’s crucial to know what it means by the grade of oil. You can figure it out by checking the car’s instruction manual. In the next section, we will discuss the details of the important terminologies of engine oil to help you make the best choice for your car engine.
API Standard: The Indian Petroleum Institute has set a standard to classify engine oils. The classification is based on performance. Your car manual clearly mentions the API standard recommended by the manufacturer.
Viscosity Grade: It determines the thickness and stress holding capacity of engine oil. Thin engine oil is fine for winter but a higher grade always works well in summer. This explains why the cars, which offer excellent performance at higher temperatures, come with engine oil of high viscosity grade.
Viscosity is expressed through a set of two numbers. For example, 0W-40 or 10W-30. Engine oil with a viscosity grade of 0W-40 implies that the car takes a start even in freezing conditions. A viscosity grade of 10W-30 is good for the places where the temperature is a little bit high.
In the example of 10W-30, 10W refers to viscosity and ‘30’ denotes the thickness of the engine oil at 100 degrees Celsius. Your car manual surely mentions the ideal oil grade for your car. Make sure to follow the recommendation. Engine oil with ‘40’ grade is considered thicker and can perform better in warm conditions.
Types of Engine Oils
There are 3 different types of engine oil for use in cars:
- Systemic Oil
- Mineral Oil
Synthetic oil offers the best protection to various car components against wear and tear caused by acceleration, brakes, and clutch usage. Therefore, if you regularly drive in a high traffic condition, it makes sense to pay for synthetic oil. It will result in lesser sludge build-up and ensure greater mileage.
Semi-synthetic oil is a cost-effective choice. Go with it if your car runs less than 10, 000 km annually. Semi-synthetic oil needs changing after 12 months or covering 6000-7500 km. Compared to synthetic variety, semi-synthetic oil is an inferior option for protecting the vital components of your car.
Mineral oil is best suited for small engines. It’s also a pocket-saving option. Mineral oil has a changing interval of 6 months or 5, 000 km, whatever comes first.
Always check your car manual to know the recommendations about engine oil. Also, follow the instructions for the replacement cycle.
