Using a high mileage oil in a low-mileage car has both its benefits and drawbacks. Some of the benefits of using a high mileage oil are given below:

Older engines easily collect sludge and dirt, which come as leftovers from other motor oils. A high mileage oil helps to dissolve and break-up the dirt and sludge. 

Increases Engine’s Longevity:

Cars that have traveled a lot face more damage compared to new cars. High mileage oils have a number of components that protect the engine parts and ensure the engine’s longevity.

Switching back to a regular oil can cause the engine seals to shrink once again, resulting in the engine having even more leaks.
