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.

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.

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

If you're not using this on your car, you're not giving your car the treatment it deserves. Sea foam has multiple uses and I've tried them all. I've been using this product for years and I can honestly say it's the best thing on the market. Don't bother putting anything in your gas tank besides this. It will clean and maintain your injectors like nothing else I've ever used. It even provides a little pep to your vehicle while in the tank. I recommend using it with each oil change to maintain performance. It has proven effective on vehicles 20+ years old. It has restored the performance and gas mileage. It can be used as an additive in your engine to break down oil deposits and gunk. I only recommend adding it for this purpose at about 100 miles before an oil change. Your oil will be black from all the gunk that comes out so don't be alarmed. You don't have to do it at every oil change, but it can't hurt especially if it's an older vehicle. The third use is that you can run it through a vacuum line into your intake. This takes a little mechanical know how and is not recommended for everyone. It will burn out the carbon deposits that have built up and will restore lost performance. If you don't know how to do this they make an aerosol version that is much easier to use. All instructions for use and products can be viewed on their website. Do yourself a favor and get some sea foam for your vehicle today.

There's all kinds of fuel treatment gimmicks out there for sale, but I've found only a few worth buying. There's this Sea Foam product that's great for any and all fuel system ailments. And there's Heet that's mainly for moisture in the fuel. The rest of the stuff on the shelf is likely just something to sell.

        As the title says, this is the real deal. Can be used to treat fuel system and crank case to loosen sticky valves. I use this as an additive in all my vehicles and rely on it to help keep them running smooth. Use it in a spray bottle to clean your throttle body. Cleans quick without a lot of trouble. I recommend this product over any other fuel system cleaner on the market.

                • 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!

                    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.

                    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

                    No, Scott, you need not have top drain the oil before using the product. Sea Foam Motor Treatment is safe for both long-term cleaning and short-term, pre-service cleaning. Using Sea Foam Motor Treatment in your oil, at 1 ½ ounces per quart, is a safe way to clean a crankcase and quiet noisy lifters as you drive.
