Engine Oil Maintenance: Myths and Realities

As a car owner, you've likely heard that engine oil is the 'lifeblood' of your vehicle.

It not only lubricates the engine's moving parts but also helps remove deposits and maintain optimal temperature.

However, there are numerous misconceptions about engine oil changes that persist.

Let's dive into some common myths and uncover the truths behind them.

Synthetic Oil: Is It Always the Best Choice?

For modern cars, synthetic oil generally outperforms mineral and semi-synthetic oils due to its superior lubricating and detergent properties.

It's more resistant to the stresses of hot weather and stop-and-go traffic.

However, when it comes to classic cars, synthetic oil can do more harm than good.

The detergents in synthetic oil can damage the oil seals in older engines, leading to leaks.

Classic cars usually benefit more from mineral oil, which is formulated to work with the metal alloys used in their engines.

My Mileage Is Short. I Can Stretch Out the Oil Change Intervals

Skipping or delaying oil changes can seem harmless, but it can lead to engine damage over time.

Manufacturers set oil change intervals based on mileage, time, and driving conditions to ensure optimal engine performance.

For example, if your oil change is due at six months or 10,000 km, waiting until 10,500 km or seven months might not cause immediate damage, but consistently stretching these intervals can degrade the oil and harm your engine.

Severe driving conditions, such as stop-and-go traffic, short trips under 10 km, and dusty environments, necessitate more frequent oil changes.

Changing the Engine Oil Is Good Enough. No Need To Change the Oil Filter

It might be tempting to skip changing the oil filter to save money, but this can lead to long-term engine damage.

The oil filter traps harmful deposits, keeping your engine clean.

Without a fresh filter, these deposits will circulate in the engine, causing wear and potential clogs.

Replacing the oil filter along with the oil is crucial to maintain engine health and prevent costly repairs.

Preventive maintenance is always better than dealing with breakdowns.

My Driving Conditions Are Not 'Severe'. So, No Need To Change So Often

Many drivers believe that lower speeds and short distances are less stressful on their car.

However, engines perform best at moderate to high speeds.

Low speeds and short trips prevent the oil and engine from reaching optimal operating temperatures, reducing the oil's effectiveness and leading to sludge buildup.

Engines need to run at higher temperatures to burn off carbon deposits and maintain their protective properties.

Therefore, frequent short trips and slow-moving traffic are actually considered 'severe' conditions for your engine.

Low Mileage Doesn't Mean No Oil Change

A common myth is that if you drive less, you can extend the interval between oil changes.

Even if your car has only clocked 3,000 km in six months, the oil still ages and loses its lubricating and detergent properties over time.

Think of oil as a moving part that wears out and needs regular replacement to ensure your engine's moving parts remain protected.

Sticking to the recommended oil change intervals, regardless of mileage, is essential for maintaining engine health.

Conclusion

Regular oil changes are critical for keeping your engine running smoothly and efficiently.

By understanding and debunking these common myths, you can make informed decisions about your vehicle's maintenance.

Always follow your manufacturer's recommendations for oil type and change intervals, and don't overlook the importance of replacing the oil filter.

Taking these steps will help ensure your engine's longevity and performance, saving you from costly repairs in the long run.
