    Default Seafoam...how often?

    Been checking out the old threads about Seafoam and still have a few questions. I have a 1999 Suburban with a 454 engine and 120,000 miles. I have never used the stuff but want to start. Do most folks use it in the crankcase at every oil change, once a year, or other? As to using it as a fuel additive...same question...how often? Do you use it with a full tank, half a tank, etc?
    Thanks.

    I use it to clean the throttlebody, the spray can and put a can in the fuel tank per the cans instruction. Once a year should be fine. Go to the website and they have several videos to watch.

    When this stuff is added to the gas tank is it a good idea to change the fuel filter after 100 miles or so of driving?

    If you add to the gas tank do it just before a oil change because some of the carbon and other dirt will end up in the oil, also I would run a full tankful and then change the fuel filter.

    I do seafoam in gas tank and vacuum line once a year. In Oil 2-3 oil changes in a row, then not again for the next 4 or 5. Just my method, others have their own.
    SEAFOAM, I PUT THAT @#!$ IN EVERYTHING!

    I do the intake yearly in the spring since the motor up here idles more in the winter. I do the oil once every 4-5 oil changes.. and once in the tank in the spring as well.
