Regular servicing is crucial for the longevity of your vehicle. The engine is the heart of your car. Keeping it in the best shape possible will ensure you get to where you need to be. Replacing the oil and filter at regular intervals ensures the moving parts within your engine will last for as long as possible.
Allowing your oil level to fall beyond the minimum recommended level can cause terminal damage to your engine. Check this regularly. Either with the dipstick or the electronic level sensor. Whichever your car is supplied with.
