    I tried to change my fuel filter today, but the main bolt will not budge AT ALL. I'll try my luck at it again next week, otherwise i'll have to pay $40+filter at my local mechanic.. :(

    Would it be counterproductive to add fuel injector cleaner now before I change the filter, or does it not matter?

    I'd get that filter off either way. The bolt won't budge...is it stripped or just right? How about rusty?

    Looks like it's rusted...I tried to use some spray I bought for taking care of rusted bolts, it still wouldn't budge... :(

    I drive 110 miles/day to get to work and back so i'm just trying to change simple things to get my mileage up (only getting 33mpg right now)...

    What spray did you use? How about trying some WD40? Also, tapping the bolt with a hammer may help loosen it up, but be careful not to damage anything.

    No, the fuel filter is before the injectors.. obviously.

    It won't matter, it will still help clean your injectors.

    If you have a high mileage vehicle you should replace the fuel filter once a year.

    So would 90k without changing the fuel filter be bad?

    It's a few dollars and a few minutes in most cars, cheap preventative maintenance.

    It's easy to change. Just google it if you're not sure, there are plenty of DIY automotive guides.

    Always run the fuel injector cleaner through the system before changing the filter,the cleaner will dislodge any sludge and debris in the gas tank,if you change the filter first you are shortening the life span of the new filter.

    since fuel injector cleaner is useless, it won't hurt or help anything anyway.
