Engine oil plays a critical role in keeping the engine running smoothly. It reduces friction between engine parts, cleans dirt, cools the engine, prevents rust, and seals gaps.

That's why it's often called the “lifeblood” of a car. Since the engine is like the heart of the vehicle, only good-quality oil can protect it, reduce wear, and extend its lifespan.

<h3>New Car? It's Time to Talk Oil!</h3>

When we get a new car, it's exciting to take it out for a spin. But before we know it, the first service is due! At that point, we start thinking about how to maintain the car properly. One of the most important things is choosing the right engine oil. Don't worry—Lykkers, we've got everything you need to know right here!

<h3>What Are the Different Types of Engine Oil?</h3> <h3>Full Synthetic Oil</h3>

Full synthetic oil is the highest quality option. It provides smoother cold starts, better fuel efficiency, and longer oil change intervals—about 1.5 times longer than regular oil. It helps keep the engine clean and reduces repair needs. If we're looking for the best option and our budget allows, full synthetic oil is the way to go.

<h3>Semi-Synthetic Oil</h3>

Semi-synthetic oil is a mix of mineral and synthetic oils, usually in a 4:6 ratio. It's refined through advanced hydrogenation technology and is a good transition between mineral and synthetic oil. It's close to full synthetic in performance but slightly cheaper, making it a budget-friendly option for many drivers.

<h3>Mineral Oil</h3>

Mineral oil is extracted from crude oil and is the most basic type of engine oil. It's amber-colored and looks similar to cooking oil. While it's inexpensive, it oxidizes easily and has a shorter lifespan—around 6 months, even with modern additives. Since it breaks down faster, it requires more frequent changes.

<h3>What Do Oil Numbers Like 5W-30 Mean?</h3>

We often see numbers like 5W-30 or 10W-40 on oil containers, but what do they mean?

• The “W” Number (Winter): The number before the “W” indicates how well the oil flows in cold weather. A lower number means the oil remains fluid at lower temperatures, which helps with easier cold starts.

• The Second Number: This indicates the oil's viscosity at high temperatures. A higher number means thicker oil at high heat, which protects the engine better but may increase fuel consumption.

For example, 5W-30 is suitable for cold climates because it remains fluid at temperatures as low as -30°C. However, for extremely cold regions, 0W oils are a better choice.

<h3>Which Oil Is Best for Your Car?</h3>

For different car types and driving conditions, different oils are recommended.

• 5W-30 or 5W-40: These are commonly recommended oils for most cars in moderate climates.

• 10W-40 and Above: These oils are better suited for hotter regions or tropical climates.

If we're unsure about which oil to choose, it's best to refer to the vehicle's manual. It provides recommendations based on engine specifications.

<h3>When Should We Change the Oil?</h3>

The first oil change should be done at 5,000 km or within 3 months. After that, it's usually best to change the oil every 6 months or 7,500 km, depending on driving conditions.

During use, the oil absorbs impurities and debris. Changing the oil a little earlier can prevent unnecessary wear and tear on the engine.

<h3>Key Points About Oil Viscosity</h3>

• Low Viscosity: Provides less protection but better fuel efficiency.

• High Viscosity: Protects the engine better but increases fuel consumption.

• Viscosity Changes with Temperature: In cold weather, oil becomes thicker, while in hot weather, it becomes thinner.

• Lower Viscosity Saves Fuel: As long as the oil provides adequate protection, choosing a lower-viscosity oil helps save fuel.

<h3>Winter Oil Considerations</h3>

In winter, it's crucial to choose oil that suits the local climate. Using inappropriate oil can make it difficult for the engine to start and cause gear-shifting issues.

<h3>Final Tips for Lykkers</h3>

Choosing the right oil isn't just about picking the most expensive one. It's about understanding what works best for our engine and driving conditions. Lykkers, when was the last time you checked your engine oil? Taking care of our cars means taking care of our wallets too!
