I'm thinking of adding Seafoam in gas every 2 to 3 thousand miles. Will that help ? Is it ok if I add whole bottle to the gas tank during fill up ? Hope it does not hurt. How often is too much anyway, or could I just add it every gas fill up ?

2016 SGS 37,000 miles.

 

1) Will it help what?
2) I would never dump a whole bottle into the gas tank.
3) Put gas in your tank and ride. No need to dump stuff into your tank. I put some in at the end of the season. Thats it.

 

1 ounce per gal , that's all . I put some in right before storage for the winter , that's it .

 

It does help with carbon build up on the back side of your valves and piston tops. It will also help keep your plugs clean. It is also good for your injectors. Putting some in every third or forth fill up wouldn't hurt and I am sure it would help keeping things clean. I wouldn't do it any more then that.

But ya one can in a tank is way to much. You need to read the instructions on the can. It will tell you exactly how much to put in. I only do it if I am going on a real long ride like a weekend ride or week long ride. I will put it in the first tank full when I leave the house and thats about it.

I run Seafoam yr round...1-oz/gal is all you need.

 

If you ride it, I don't. I use it in my mower, atvs, sleds, that gas can last longer. Granted I probably don;t need too. But I fill the can for the mower, and it may last for few months. I do think my sxs starts better since I use it.

Granted I went for years without it, I think the real need is end of season.

 

I use as specified on the can about every 4th or 5th fill up….

 

Just me, but I would use any additive with a little caution. More is not always a good thing, well some things it's OK.

 

^^^^^^ This ^^^^^^

I saved a carb rebuild/cleaning on my little portable generator once with it. I had let it sit too long once and it kept surging real bad while under light to medium load. After about a tank of fuel, I tried filling it with fresh gas and it was still surging so I mixed in a double dose of Seafoam and after about 15 minutes of a heavy load, it cleared up never to return again. I now store it with Seafoam and pull it out of the shop once a month and run it for about 15 minutes. Problem solved.

 

Have you ever heard of Top Tier gas? The web site explains it, but briefly certified top tier gas contains detergent additives that meet the BMW 100,000 mile certification to keep engine parts clean. Check the fuel brand you normally use and if it is on the list, any additional additive (beyond end of season stabilizer) is unnecessary. If you use a brand of gas not on the list, once or twice a year for Sea Foam or any other fuel system/injector cleaner should keep things working well. My choice, Berryman Chemtool, has some pretty strong stuff in it, acetone among them so mixing above the recommended concentration can harm various components. The idea is not much different from E10 gas, ethanol can be tolerated by fuel system components up to a point, in higher concentrations, it will harm certain components.
