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 always makes my engine run smoothly and can notice 1-2 mpg. You can add it to the gas tank, oil, and unhook a vacuum line to let it clean the upper end of the engine.

Comments about Sea Foam Motor Treatment for Gas and Diesel Engines (16 fl. oz.):

Seafoam rocks!! Seriously this is some great stuff with many uses. I added 1/3 to my gas, 1/3 to my oil and 1/3 through my intake. There is a small learning curve involved, but this is 2017. That's why we have Youtube. Check out some videos on Seafoam before you use it and you will achieve the results you want. My Jeep is old and I DD it as well as take it off road. Seafoam keeps my engine running smooth!

      A:

      Hi Jose, I am happy to help! This Sea Foam Motor Treatment for Gas and Diesel Engines (16 fl. oz.) (Part No. SF16) is a great way to help your car perform better. Justpour into a full tank of gas, and yes it goes directly through the tank. Sea Foam cleans and restores lost engine power by dissolving petroleum deposits and residues and also lubricates upper cylinder parts for longer engine wear life and helps protect the entire fuel system from corrosion.

  • 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!

      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.

  • Q:

    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?
