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.

    This stuff is amazing. I have used it in my mustang since day one in my oil, gas tank, and vacuum lines. Just make sure to follow the directions exactly and it will work great if sludge and carbon build up are your issues.

      Non-harsh chemicals to remove water/moisture from your engine or fuel. Also stabilizes the ethanol in fuel to keep it from damaging vehicle parts while in storage. If you ride ATVs, UTVs, Jeeps, etc it's great product to have on you.

        Is sea foam motor treatment acceptable for use in my anti-slosh foam filled fuel cell (the type used on race cars) or will it deteriorate the foam and clog the fuel delivery system?

      • Q:

        How long does it take to see results, do you have to use up the entire tank until you see results? I had an empty tank when I put this treatment in my vehicle and it seems to have already started to work but I was not sure if it takes a certain amount of miles to be ran on the car or maybe a full tank to see full results.

        Thanks!

        • CUSTOMER CARE

          A:

          Hi Wendy, I'm happy to help you! To maintain a healthy engine or when stabilizing stored fuel, Sea Foam's maintenance recommendation for all fuel types is 1 ounce per gallon of fuel. One pint treats up to 16 gallons. One gallon treats up to 128 gallons. Just pour directly into the tank. For engines that replenish fuel regularly, use 1 or 2 cans every 2,000 to 5,000 drive miles. For engines using fuel older than 3 weeks, add Sea Foam to every tank of fresh fuel. Remember that Sea Foam in your tank at all times is always cleaning and lubricating the entire fuel system.

        I'm having issues with my car losing a little bit of power going uphill. It's barely noticeable, but I notice it. No one else seems to. It's a 2006 Chevy Impala with 205,000 miles. It looks brand new inside and out so I continue to drive it until the wheels fall off. I assume this Sea Foam goes directly into the gas tank?

          A:

          Hi Zman, I'm glad to assist you. Replacing the Intake Idle control valve would be a better solution. Without the presence of your vehicle we would not be able to properly diagnose it, nor provide you with a 100% answer. I would suggest that you take your vehicle and get it thoroughly checked by a certified mechanic before buying any parts that may/may not solve the problem.

          A:

          Great question Thomas, I will be happy to help. I can tell you it certainly won't hurt your engine and a great place to start. You may have other issues going on but Sea Foam will definitely clean out the fuel system. To clean the carburetor bowl and jets the manufacturer recommends that you add 2 oz. of Sea Foam Motor Treatment to each gallon of gas oil mix. Sea Foam Motor Treatment will slowly re-liquefy old fuel and petroleum varnish residue deposits, clearing passages and restoring normal functionality. If you wish to spray atomized Sea Foam Motor Treatment directly into the carburetor throat with the engine warm and running, use Sea Foam Spray Top Engine Cleaner and Lube (Sea Foam Motor Treatment in an aerosol can). - See more at: http://seafoamsales.com/cleaning-two-stroke-engines/#sthash.B6elswzw.dpuf
