1. To Prevent Sludge From Building Up in the Car Engine
As the car runs, debris such as dust, antifreeze, condensation, and shavings may be picked up, which will contaminate the oil.
This will form sludge when mixed in the oil, which can stick to motor parts and cause engine wear. By regularly changing the oil you can prevent this build up.
2. To Change the Engine Oil Filter
The oil filter is the car part meant to help reduce the contaminants that can eventually form sludge. This needs to be changed often.
3. To Preserve the Lubrication of the Engine
Motor oil prevents friction in the motor. When it runs out or is very old, the engine parts will rub together, which can lead to the destruction of the engine.
4. To Make Sure the Level of Engine Oil is Properly Full
If your car doesn’t have a low level oil indicator on the dashboard, there is a risk of causing serious damage to the engine. It is best to locate the engine oil dipstick and check the level of oil, every month or before a long journey.
