Forgive my ignorance here, never done any of my own work on a car but with my new (to me) fiesta st I'll be keeping her in tip top condition so will have lots of questions! When it comes for new filters how do I know when I need a new one?
Coolio, was serviced this year and is at 53k so I hope it should be cool, but for arguments sake what would it look like/feel like or anything to indicate it was time for a new one?
