How to Determine Which Oil Suits Your Car’s Engine

First and foremost, you should consult the car’s maintenance manual.
If the manual is not available, check with the official representative of your car’s manufacturer to find out the required specifications for the engine oil.

If you have just purchased the car, find out what type of oil was previously used in the engine.

If you cannot verify this with the previous owner, the engine should be flushed before adding new oil.

If you know what oil was used before, the next step is to decide whether it is advisable to continue using the same oil or switch to a new one.
If the previously used oil has the approval of your vehicle’s manufacturer, you can confidently continue using that oil.

If the previously used oil causes problems—such as excessive oil consumption—it may be necessary to switch to a thicker oil.
In such cases, it is essential to consult with a specialist.

While switching to a new type of oil can potentially harm the engine if done improperly, running an engine with incompatible oil can cause it to fail quickly.
It is better to switch to the correct and suitable oil after flushing the engine thoroughly.
