The role of engine oil is to coat the components of the engine in lubricant, reducing friction where these parts interact. This prevents wear, reduces emissions, maximises engine performance and improves the lifespan of critical engine parts - provided you choose the right product for the job.

If you own a vehicle, either as an individual or a business, changing its oil regularly is an essential part of routine maintenance. As oil flows through an engine, it accumulates various contaminants that render it less effective, which is why it needs to be changed regularly.
