As a once or twice a year use to help remove deposits in fuel injection or carbs, it's good. Not for every tank of fuel. Also, Chevron Star Tron does the same however it is more foe fuel injection systems I believe.

Do you have a specific concern?

I get pure gasoline and add sea foam if I let a vehicle sit for a while...otherwise I just fill my vehicles with reggie and maybe once a month I’ll get a tank full of premium.

I ride an older Nighthawk with no fuel injection. I use Sea Foam every 4-6 months or so or anytime it starts to run a little rough. It works great for keeping the carbs free of gunk. Any time it's on sale I stock up on it.

I have two bikes, both fuel injected. During times when both bikes are seeing regular use, like now, I focus on keeping their tanks full to prevent condensation build-up in the tanks, and I'll add a shot of Sea Foam every couple of weeks just to keep things clean. In periods of low use, I not only keep the tanks full but add the recommended 1 oz. of Sea Foam per gallon at fill-up and run them enough before storage so the SF gets distributed thru the system. Both bikes are rated for use with regular gas with up to 10% ethanol, and that's what I put in them 95% of the time. And about 100 miles before each oil/filter change I will add the recommended 1 oz. per quart of SF to the crankcase oil, which helps loosen up any crud build-up and keeps things nice and free-flowing there, too.

According to the company, Sea Foam is perfectly safe for fuel, lubrication systems, and catalytic converters, and there's no such thing as adding too much -- just no real added benefit over the prescribed dosage.

When I first got my Goldwing, it had been sitting for a couple of years. It didn't run or idle very well at all.
Over a week or so, I ran two whole cans of seafoam through it.
All the problems cleared right up and it's been running fine ever since.
Much easier than taking the thing apart and cleaning carbs and such.

I always wondered about that but I'm too cheap and too chicken to test that. The roads I travel have no cell service and it could be several hours before someone happened by to get help. I have gone half again the recommended amount on bikes I was unsure of their maintenance but stayed fairly close to home during those times. So good to know it does no harm except wallet. I'm sure others will like knowing that as well.:thumbsup:

I have used it on bikes with carburetors when they started running a bit rough and had good results. Used it at every fill up until the problem went away, after that I'd use it maybe once every month or two.

Thank you everyone who gave their personal experience. It looks like everyone has good things to say about Sea Foam. I picked some up today and will be adding it to my bike and my wife's bike.

My next question is, do you guys fill up your tank and then put the Sea Foam in?
Do you let it sit for a little while or just go out and ride? What is your usual process?

I prefer to put it in when the tank is between half to 3/4 full and then fill up right afterwards. I don't think it really matters but I like knowing for sure that it's getting "mixed in" with the rest of the gas in the tank.

I would pour it in first, and then fill it up and ride. Don't know if it really makes any difference but just felt like it got more mixed in with the fuel that way.

I've even put the stuff in a already filled tank if I immediately rode away. I didn't see a problem. I figured the vibration and sloshing would mix it and I guess it worked.

I use Seafoam in everything that I have with great results. Mowers, weed eaters, blower/vacs, snow blowers, pressure washer, snowmobiles, and motorcycles. At times, our vehicles even get a taste of it. It also works great as a fuel stabilizer during the offseason for the seasonal stuff.
