The oil filter of your Vauxhall ensures the engine oil is cleaned from damaging particles.
As the oil flows through the Vauxhall's engine, numerous particles find their way into the oil. Some are created by the combustion process in the engine, others by the normal wear of the engine and some come from outside the vehicle.
The oil filter takes up these particles thereby protecting your Vauxhall's engine from getting damaged because the oil is not clean. To ensure the oil filter does not clogg up, we recommend you replace it regularly; every 9000 miles for a petrol engine and every 18 600 miles for a diesel. Fortunately oil filters are relatively inexpensive car parts: for less than $20 you have a new one for your Vauxhall.
To ensure you buy the right oil filter for your Vauxhall though, please fill in your model and engine type.
