    Water Contaminated Fuel

    Just got back from Road America and made the mistake of refueling at Marshall's One Stop in Downtown Elkhart Lake not to mention they only had 91 octane but I believe the fuel was contaminated with water. I had nothing but issues with the engine sputtering and stalling out on my way home which is no fun at speed and 9pm. Reported them to the Wisconsin Dept. of Agriculture hope that helps, anyone else fill up there? Luckily I had close to half a tank prior to the fill-up and stopped halfway home to add more good fuel. Seems to be running okay now but do you think I should add a can of Heet?

    What kind of car? MFI cars with water contamination will cause the paper in the filter element to swell and cause fuel pressure to drop. Hope you made it home, good luck.

    If you have carbs, it is more of a problem, as the water will settle at the bottom of your float bowls. Add a can of alcohol based dryer and drive the car till empty.
    You could also drain a couple of liters out of the tank, after sitting for a while.

    FIRST drain your float bowls Mike.

    Sorry we didn't get to chat at the track; knee-deep in alligators the whole weekend.

    Yep, car stalled on me twice south of Milwaukee, limped home. Car seems ok now, already got a call back from the Wisconsin Dept of Agriculture and they will be out for a tank inspection tomorrow at Marshall's One Stop. We would never get this kind of quick response in Illinois. What kind of idiot would fill their car up at a place called Marshall's One Stop anyway, lesson learned.

    Interesting. Is that anecdotal or did you dissect a filter? I had a similar experience this WE with an MFI engine , after a season of non use and a fill up. Ran great for a couple of hours and tried to drive it after turning it off for 15 minutes. It sputtered and backfired, eventually getting better, but still not back to it's earlier drivability. I am planning on checking the plugs and possibly adding a fuel treatment, which may help with deposits but not water.
    A collapsed or blocked filter would be an easy remedy.

    A bottle of Techron Concentrate Plus will help as well...

    That sounds more like a clogged strainer at the bottom of the tank. Of course by removing the strainer you will also take care of any water at the bottom of the tank. I don't think Techron will help with the water, alcohol is needed to absorb the water and move it through the system. It really depends how much water is there.

    "Marshall's One Stop" sounds like the perfect name.
