I see a post on Reddit said Mazda require owners to replace their fuel filter every two years or 30K miles whichever come first. How come my dealership never said anything about fuel filter, I only have 10k on my cx-5 right now, but it is about 2 years by now. I am not sure should I go to dealership to replace it, or just wait until I hit 30k miles? I always do oil change myself, I don't see any how to on internet for change fuel filter on a cx-5. Does anyone DIY this before?
