Every 2 years
How often should you change the fuel filter?
Every 30,000 miles.
every 12000 miles
It depends on how much you drive it. It could also depend on what type of fuel you use. You should change the fuel filter between 30,000 miles clear up to 100,000 miles. or if your car does not start and there is no fuel in the filter, then you can change it then.
I don't know what you mean by so often. Change your fuel filter every 75,000 miles and you will be fine.
I recommend every 50,000 miles.
Should change the filter at least 2 times a year. Remeber the fuel is always being pasted thru the filter. But if you get to it once a year that is better then not doing it.
