Yes. For ISF2.8 and ISF3.8 engines, these symptoms often indicate a saturated fuel water separator. Replacing your FS36257 filter immediately prevents water from reaching the fuel pump and injectors, which could otherwise cause thousands of dollars in damage.
Under normal conditions, it should be replaced every 15,000 to 20,000 km or during every oil change. In high-humidity environments or areas with poor fuel quality, more frequent inspection is recommended to ensure the FS36257 continues to protect your engine.
