What is synthetic oil and what benefits does it offer?

Synthetic oil is a lubricant developed using advanced technology, and it has become a key choice for those looking to protect their engine—whether it’s in a car, motorbike, or even diesel engines.

In this article, you’ll discover how it differs from mineral oil, what its real benefits are, and why choosing synthetic oil can make a significant difference to your vehicle’s performance and lifespan.

What is synthetic oil?

Synthetic oil is a lubricant that goes through several stages of processing, including synthesis, from carefully engineered chemical compounds.

Unlike mineral oil, synthetic oil has a uniform molecular structure, allowing it to deliver superior and consistent performance.

Thanks to these properties, you get a lubricant that better resists oxidation, withstands high temperatures, and effectively protects engine components against wear—even under demanding driving conditions.

Differences between synthetic and mineral oil

The main difference between synthetic and mineral oil lies in their composition and level of purity. While mineral oil is refined from crude petroleum, synthetic oil is produced through controlled chemical processes. This gives it a significant advantage in terms of thermal stability, protection, and efficiency.

There are also semi-synthetic options that combine properties of both. Understanding the difference between mineral, semi-synthetic, and synthetic oils is essential for choosing the ideal lubricant based on your vehicle type and usage.

What are the benefits of synthetic motor oil?

1. Superior wear protection

Synthetic engine oil offers excellent friction control, which reduces the impact of direct contact between internal engine parts.

This feature is essential to reduce friction and excessive heat, especially in high-performance engines or under demanding driving conditions.

Thanks to this protection, you help prevent premature wear and keep your engine running efficiently for longer, reducing the risk of costly breakdowns and providing greater confidence while driving.

2. Longer intervals between oil changes

With synthetic oil, you benefit from improved resistance to oxidation and thermal breakdown, allowing it to maintain its lubricating properties over more kilometres.

For light vehicles, the typical oil change interval is around every 5,000 km, but full synthetic oil can last up to or even beyond 10,000 km. However, this depends on several factors such as the vehicle’s maintenance quality, driving habits, and engine characteristics.

This translates to fewer maintenance services and significant savings over time.

3. Better performance in extreme temperatures

Full synthetic oil maintains better viscosity control during high operating temperatures, allowing it to perform well in both extreme heat and cold without losing its lubricating ability.

This means whether you’re driving in scorching heat or freezing temperatures, the oil maintains appropriate viscosity and protects every engine component.

This thermal stability ensures your vehicle always performs at its best, avoiding failures due to overheating or lubricant degradation.

4. Flow efficiency in cold starts

In cold weather, many conventional oils tend to thicken, making lubrication difficult during the first few seconds after starting the engine. With synthetic oil, you get immediate flow even in such conditions.

Its composition allows it to circulate quickly throughout the engine, protecting critical parts from the first turn of the key. This reduces initial wear, extends engine life, and improves efficiency in areas where cold starts are common.

5. Reduced sludge and deposit formation

Synthetic oil has superior resistance to degradation, which minimises the formation of deposits, sludge, and sediment inside the engine.

By keeping the internal system clean, you ensure that parts operate without blockages and that the engine maintains consistent performance.

This internal cleanliness also helps extend the life of other vehicle components, such as filters, thereby reducing long-term maintenance costs.

When is it advisable to use synthetic oil?

Whether for cars or motorbikes, synthetic oil is an excellent choice if you prioritise performance and protection at all times.

It’s especially recommended if you drive a modern vehicle with advanced technical requirements, operate a diesel engine that demands maximum efficiency, or take long trips where the engine is under constant strain.

If your gearbox allows it, you may also consider synthetic oil for manual transmissions, further enhancing your vehicle’s overall performance.

How often should synthetic oil be changed?

If you’re wondering how long synthetic oil lasts or how often it should be changed in a light vehicle, the answer is that it typically stays effective for up to 10,000 kilometres on average.

However, not all engines or driving styles are the same. It’s important to follow your vehicle manufacturer’s recommendations.

Your driving environment—urban, highway, or extreme conditions—also plays a role. Adhering to recommended intervals ensures you get the most from full synthetic oil and keep your engine in top condition.

Can you switch from mineral to synthetic oil?

Yes, switching from mineral to synthetic oil is possible without any issues—provided you follow your vehicle manufacturer’s recommendations, such as viscosity grades, technical specifications (e.g. API or ACEA), and OEM requirements.

If these are met, switching will not damage the engine. On the contrary, it may offer noticeable improvements in protection, cleanliness, and performance. Some prefer a gradual transition using semi-synthetic oil, but it’s not mandatory.

Be sure to carry out a full oil change and use new filters to maximise the benefits of synthetic oil for your car or motorbike.

Now that you know what synthetic oil is, how it works, and its main benefits, you’re well-equipped to choose the best lubricant for your vehicle.

Frequently Asked Questions

Is synthetic oil better than mineral oil?
In most cases, yes. Synthetic oil offers better protection, cleanliness, and durability. However, always consult your manufacturer before making a decision.

Can I mix synthetic and mineral oil?
Yes, but it’s not recommended. While it won’t cause immediate harm, it reduces the advantages that synthetic oil offers.

Does synthetic oil damage the engine?
On the contrary. When you choose the right synthetic lubricants for your vehicle, they enhance performance and extend engine life.
