i have about 9,000 miles since my last fuel filter change, pettit racings site is down regarding maintenance, so i thought i ask after how many miles should you replace the fuel filter? i use octane 94 everytime.

 

I think the factory manual says 30k. But I know "everyone" on here does it probably more like 5-6k (every 2 oil changes or so) But thats overkill in my limited opinion

 

Actually, the manual says 60 months (5 years) or 60 thousand miles (pg A-3). I would rather go about half that, but I'm a little ****.

5-6K??? Whoever does that babies their 7 waaaay to much. I would say 30,000 just like flyrx7 said...in a way. Thats when I changed mine.

 

I think 15k is a pretty good rule of thumb. Considering how crucial fuel delivery is on these cars.....

30K

 

Hmm, I recently changed my fuel filter... it was well worth the trouble let me tell you. A tremendous improvement in throttle response.

 

I agree with rynberg, or every 2 years.

 

30 K should be fine....

 

thanks guys

 

I would stick with mazda recommendation at 60k unless you're having performance issues.

I did change mine at 30k and didn't notice any change. I think my next one will be another 60k mi.

 

15k is what I have heard and I do since it's no big deal but the guy who rebuilt my engine says that's excessively conservative.

 

Huh? 60K?

 

I just change mine whenever I change my engine

 

I do the fuel filter every 15k miles. I do my oil every month regardless of miles. I usually put like 6-7k miles a year on my FD.

 

Yeah, like I said - every 15k

 

im in the process of tearing my whole car apart.. and when i was undoing the exhaust i noticed my f'in fuel filter wasnt even hooked up//it was totally bypassed.. isnt that lovely.

 

I'd trace the fuel line all the way from the pump to the injectors and make sure they didnt install another filter like the K&N fuel filter or something in a different location.....its very common to relocate the filter so its easy to change

I do it every 10K.
