Hello,
How often should you change a fuel filter? I have a C3 diesel and the Haynes book says to replace it after four years or 40,000 miles. I asked the dealer for a price last year and it was so expensive I did not buy one. An independent mechanic told me not to worry as he said it was not due yet, contradicting Haynes.
I was looking at brakes on the eurocar parts web site and thought I would look at filters at the same time. In their blurb they say the fuel filter should be changed every two years at the very least, preferably once a year.
Is this a ploy to get you to buy four times as many as necessary? How often should they be changed?
TIA
