1. Effects of using various oils on car engines

In practice, using different engine oils with varying viscosities over a short period will not cause immediate problems, and the vehicle will run normally without major concerns. However, if this continues for an extended period, it can significantly impact engine performance and longevity.

To ensure smooth and stable vehicle operation, you need to select and change the motor oil with specifications and viscosity that suit the type of engine you are using. For example, Ford gasoline vehicles should use 5W30 oil, while Ford heavy-duty diesel engines should opt for 15W40, as recommended by the manufacturer. You can also refer to the owner's manual for each model for the most accurate selection.

Additionally, if you must switch to a different viscosity oil than what was previously used, it is advisable to flush and clean the engine before adding new oil. This will help remove all old oil, preventing mixing that can lead to poor circulation and engine damage.

Using different types of motor oils with varying viscosities can cause damage to your car over time.
