Synthetic vs. Conventional Engine Oil: Which One Should You Use?

Engine oil is an essential element that guarantees the smooth operation of your car’s engine.  There are two main types of engine oils available in the market today: synthetic and conventional. Both have benefits and drawbacks. So, picking the right one can have a big impact on your car’s efficiency and durability.

The primary source of conventional engine oil is crude oil. It has been used in cars for decades and is the most common type of engine oil available today. Synthetic engine oil, in comparison, is man-made and is produced to offer better performance and protection than conventional oil. It is made of chemical substances engineered to offer your car’s engine superior lubrication and protection.

The Difference Between Conventional and Synthetic Oil

Composition:

Conventional oil is derived from crude oil and contains impurities such as sulfur and wax. 

Synthetic oil, on the other hand, is made from chemical compounds and has fewer impurities, resulting in a more uniform and consistent molecular structure.

Performance:

Synthetic oil offers better performance and protection than conventional oil. It has better resistance to high temperatures, which helps to reduce engine wear and tear, and also provides better fuel efficiency.

Conventional oil may break down more easily under high temperatures, which can lead to engine damage and decreased fuel efficiency.

Price:

Synthetic oil is generally more expensive than conventional oil because it requires more advanced manufacturing techniques and higher-quality base stocks. In comparison, 

Conventional oil is more affordable and widely available.

Frequency of Changes:

Synthetic oil can last longer than conventional oil, often requiring fewer oil changes. However, 

Conventional oil typically requires more frequent changes due to its shorter lifespan.

Compatibility:

Conventional oil is compatible with most vehicles and can be used in older engines without encountering any noticeable issues. 

But, synthetic oil may not be suitable for all vehicles and may cause issues in older engines not designed to handle its properties.

Environmental Impact:

Synthetic oil is more environmentally friendly than conventional oil because it is made from chemical compounds rather than crude oil.

Conventional oil can release harmful pollutants into the atmosphere if you do not dispose of it properly.

Is Synthetic Motor oil Better Than Conventional?

Understanding whether synthetic motor oil is better than conventional motor oil requires you two understand some important factors. The type of engine, the traffic situation, and individual preferences are just a few of the variables that affect the response to this question.

First off, synthetic motor oil typically performs better than conventional motor oil. Your engine will perform and last longer thanks to the improved lubrication and protection that synthetic oil gives you.  It is also resistant to breakdown and sludge buildup and can withstand high temperatures.

Synthetic oil also offers better fuel efficiency, which can save costs over time.

Contrarily, typical motor oil is made from crude oil and might include impurities like wax and sulphur. Despite being widely accessible and reasonably priced, it might not offer the same level of protection and performance as synthetic oil. Changing conventional oil more frequently than synthetic oil can be time-consuming and expensive.

But not all engines may be compatible with synthetic oil. Some older engines or engines with high mileage may not be able to handle the properties of synthetic oil, and it may cause leaks or other issues. Additionally, synthetic oil is more expensive than regular oil, which may discourage some car owners from using it.

Overall, synthetic motor oil is considered better than conventional motor oil in terms of performance and longevity. But, this oil might not be appropriate for all engines, and given its higher price, it might not be as appealing to car owners with a limited budget. We recommend you consult with your car manufacturer or a qualified mechanic to determine which type of motor oil is best for your engine.

Which One Should You Use?

Choosing the right engine oil is crucial for the health and performance of your vehicle. Here are some factors to consider when choosing engine oil for your car or motorcycle:

  1. Viscosity: Viscosity measures how easily oil flows at different temperatures. It is important to choose an oil with the right viscosity for your engine. The grade of viscosity recommended by the manufacturer can be found in the owner’s manual.
  2. Type of engine: Car engines and motorcycle engines have different requirements for oil. Car engines typically require oils with additives that help to reduce friction and wear, while motorcycle engines require oils that provide more protection to the clutch and transmission.
  3. Performance: The performance of the oil can be a crucial factor when choosing engine oil. Performance oils can help improve fuel economy, reduce engine wear, and provide better protection to the engine.
  4. Brand: Your engine oil’s brand can be a determining factor when choosing engine oil. An established and reputable brand like Mobil typically offers high-quality oils that have been tested to meet industry standards.
  5. Oil life: Some engine oils last longer than others, and this can be an important consideration if you drive frequently. Synthetic oils, for example, can last longer than conventional oils, which can help reduce the number of oil changes required.
  6. Price: Engine oil prices can vary widely, depending on the type of oil and the brand. It is important to choose an oil that fits within your budget, while still meeting the requirements of your engine.
  7. Environmental impact: You should also consider the environmental impact of your engine oil.  Some oils are more eco-friendly than others, and choosing an eco-friendly oil can help reduce your carbon footprint.

Conclusion

When selecting between synthetic or conventional oil, your purchase decision may be influenced by several factors like the composition and model of your car, your driving style,  and your personal preferences.

When it comes to choosing between synthetic and conventional engine oil, there is no clear winner. Both types have their advantages and disadvantages, and the choice ultimately depends on your car’s make and model, driving conditions, and personal preferences. We recommend you consult with your car manufacturer or a qualified mechanic to determine which type of engine oil is best for your car.
