When it comes to maintaining the health and longevity of your vehicle's engine, one of the most critical decisions you can make is selecting the appropriate engine oil grade.
Engine oil acts as the lifeblood of your vehicle's engine, providing essential lubrication, cooling, and protection against wear and tear. However, the variety of engine oil grades available in Dhaka’s market can be quite confusing.
In this article, we will simplify the engine oil grades and help you understand which one to use for your vehicle.
Understanding engine oil grades
Engine oil is classified by two primary characteristics: viscosity and performance. Viscosity, in simple terms, refers to how thick or thin the oil is. The lower the viscosity grade, the thinner the oil, while higher grades indicate thicker oil.
For instance, you might encounter grades such as 5W-30, 10W-40, or 15W-50. The "W" stands for winter, indicating the oil's flow characteristics in cold temperatures.
The number before the "W" represents the oil's viscosity at low temperatures (in winter), while the number after the hyphen denotes the viscosity at operating temperatures (typically 100°C or 212°F). In general, lower numbers before the "W" flow better in cold weather, while higher numbers after the hyphen provide better protection at high temperatures.
Choosing the right grade
The first thing to always do is to refer to your owner's manual that came with the car since the vehicle's manufacturer recommends a specific engine oil grade. This information can typically be found in the owner's manual or on a label under the hood.
Consider your climate: If you live in a region with extreme temperature variations, you should pay extra attention to the "W" part of the engine oil grade. A lower winter viscosity grade (e.g., 0W) ensures better cold-start protection, while a higher one (e.g., 10W) might be suitable for milder climates.
Driving conditions: The type of driving you do also influences your choice. If you regularly tow heavy loads, drive in stop-and-go traffic, or push your vehicle to its limits, you may benefit from a higher viscosity oil (e.g., 10W-40 or 15W-50) for added protection.
Synthetic vs. conventional: This is probably one of the most common questions asked by a car owner, so here it goes. Synthetic oils typically offer better high-temperature stability and flow characteristics, making them a great choice for modern engines. However, they can be pricier than conventional oils.
I personally would recommend going for the synthetic ones as the temperature during the summer in Dhaka could be quite testing for the engines.
In conclusion, choosing the right engine oil grade is essential for the health and longevity of your vehicle's engine.
Regularly checking and changing your engine oil, as per your manufacturer's recommendations, is also crucial to ensure your engine continues to run smoothly and efficiently. Try to change your engine oil at least twice a year or every time your vehicle hits 5000 km.
Remember, when in doubt, consult your owner's manual or seek advice from a trusted mechanic to make an informed decision that best suits your vehicle's needs.
