I recently purchased a used 2008 Honda Shadow Aero 750 with 5,500 original miles. The bike did not get rode frequently enough and sat for approx 10 months. It did not run very well so I drained the old gas and filled it back up with fresh high octane gas (3 gallons) and 8 0zs of SeaFoam. This stuff really helped. After letting the bike idle for about 45 mins and riding for around 80 miles the carburetor functioned much better. The hesitation and back firing stopped. I ran SeaFoam through the fuel system for two more gas tanks full and the bike got even better. GREAT STUFF! I'll be using it in my other two bikes also.

Sea Foam

Use Shell/BP in my car so I haven't noticed any difference in 5000 mi. maybe if I used lower quality gas it would make a difference.

  • Q:

    Compare seafoam to startron for treatment of diesel fuel. I have a motorhome with a cummins diesel and have been using startron periodically, but the pricing on seafoam is much better. I always use seafoam with my small engine maintenance.

      A:

      Hi John! This Sea Foam Motor Treatment for Gas and Diesel Engines (Part No. SF16) is to stabilize fuel, dissolve harmful residues and deposits, add lubricity, and control small amounts of moisture. When added to diesel fuel filters will restore injector spray patterns and reclaim lost power by removing soot and carbon from injector nozzles. When added to crankcase oil, Sea Foam will clean deposits and contamination, restoring flow to restricted oil passages.

  • Q:

    I put this in my tank along with premium gasoline. I took it out on the highway and after 4-5 miles i lost power. The engine still ran but was like car was not getting gas. Was i ot supposed to use premium gas?
    Asked on 8/9/2017 by Liz from Portland OR

    2 answers

    • A:

      Using premium should not cause your symptoms. It sounds like there may be another issue with your car. Did the check engine light come on?

      Answered on 8/9/2017 by n64andrew1 from undisclosed
    • A:

      Sounds like you have other mechanical or Electrical issues. I think it is time to take the vehicle into the Mechanic. This stuff is a strong cleaner and will not cause you to have the trouble that you did. And the Octane rating you run should not have any ADVERSE affect on the car either. Time to get it checked.

      How are you using it? In the fuel as an additive, I can't imagine any problems it could cause. It's a good product. I use it mostly for intake system cleaning.

    • A:

      Probably not. Advance sells a product called Cat Cleaner in a green and white bottle. That stuff is MUCH better than seafoam which doesn't remain potent after burned in an engine (it reached your cats AFTER it is burned, so it is useless).

      Answered on 8/7/2017 by douglas.biocia from undisclosed
    • A:

      SeaFoam will not fix a catalytic converter issue.  It could in fact make it worse.
