Filters really are your engine’s first line of defence, protecting parts by keeping out unwanted debris. Any material not caught by a filter can potentially damage the engine and, at the very least, compromise its efficiency.

In many cases, filters are small and inexpensive but, in common with anything to do with regular maintenance, servicing them is vital. Each engine will come with its own schedule of how often they need to be changed, based either on running hours or the length of time since the last change.
