Engine Oil: What It Is and When to Change It

What is Engine Oil?

Engine oil is an essential fluid for the operation of a car engine. It has several key functions:

• Lubrication: Reduces friction between moving engine parts, preventing wear and damage.
• Cooling: Helps dissipate heat produced by the engine.
• Cleaning: Removes and suspends impurities, debris and combustion residues.
• Protection: Prevents rust and corrosion of metal parts.

There are different types of engine oil:

• Mineral Oil: Derived from crude oil, it is the cheapest type and often used in older vehicles.
• Semi-Synthetic Oil: A blend of mineral and synthetic oil, it offers a good balance between performance and cost.
• Synthetic Oil: Produced through advanced chemical processes, it provides superior protection and improved performance, especially useful for high performance vehicles.

When to Change Engine Oil?

1. Follow the Manufacturer's Recommendations

Each vehicle has specific oil change recommendations, usually listed in the owner's manual. Most modern vehicles require an oil change every 10,000 to 15,000 kilometers, but some cars may require different intervals.

2. Check Oil Level and Quality

• Oil Color: If the oil appears very dark and thick, it may be time to change it. New oil is usually golden or amber in color.
• Consistency: The oil should be thin and not slimy. If it seems thicker than normal, it may have degraded.

3. Oil Light

Many cars have a warning light on the dashboard that comes on when the oil needs changing. Do not ignore this light, as it can prevent damage to the engine.

4. Driving Conditions

If you frequently drive in severe conditions, such as:

• Heavy traffic and stop-and-go
• Extreme climates (very cold or very hot)
• Dusty roads

...you may need to change your oil more often than normal.

5. Every 6-12 Months

If you don't drive many miles in a year, you may still need to change your oil at least once a year, as oil also degrades over time.

Conclusion

Changing your engine oil is crucial to keeping your engine in good condition and ensuring its longevity. Following the manufacturer's recommendations and regularly monitoring your oil will help prevent problems and keep your vehicle performing at its best.
