Can I Use Conventional Oil if My Car Requires Synthetic Oil?

When it comes to car maintenance, using the correct type of oil is crucial. If your vehicle's manual specifies synthetic oil, can you put conventional oil in your car? The short answer is no, and here's why.

Performance

One of the primary reasons for using synthetic oil in cars that require it is the improved performance it offers. Synthetic oils are specifically formulated to enhance engine protection, lubrication, and efficiency. They have better resistance to high temperatures and maintain their viscosity better than conventional oils. This means that under extreme conditions, synthetic oils can perform more reliably than their conventional counterparts.

Engine Wear

Using conventional oil in a car that is designed to use synthetic oil can lead to increased engine wear and tear. The superior properties of synthetic oils, such as better shear stability and lower volatility, help reduce engine wear. Conventional oils may not provide the same level of protection, especially in engines that are newer or tightly engineered.

Oil Change Intervals

Synthetic oils often allow for longer oil change intervals. This is because they can resist degradation over a longer period, providing better protection for longer. If you use conventional oil, you may need to change it more frequently to ensure proper engine protection. Using the wrong oil type can therefore negate the benefits of extended oil change intervals recommended by your car manufacturer.

Manufacturer Recommendations

Car manufacturers conduct extensive testing and develop specific recommendations for oil types to ensure optimal performance and safety. Using a different type of oil than what is recommended can void your warranty or lead to potential engine issues. Always refer to your owner's manual for the best recommendations regarding oil type. If you accidentally use conventional oil, it is recommended to change it to the correct type as soon as possible to avoid any potential damage.

Emergency Situations

In an emergency situation, if you have access to motor oil that is not synthetic and you intend to get your vehicle serviced immediately, then it is acceptable to use conventional oil. However, without oil, your engine will suffer severe and irreversible damage. In such cases, using any available oil is better than no oil.

In conclusion, if your car requires synthetic oil, you should always use synthetic oil to maintain the optimal performance and extend the life of your engine. Always refer to your owner's manual for specific recommendations.
