ok, got my first can of seafoam today, and was wondering, should i put some directly in the oil and some directly in the gas tank? A bunch of stuff i found on the web said to pour it in vacuum lines and what not so i just want to make sure pouring it into the oil and tank is okay as well

You should only put it in your oil if your going to change your oil. It's not an additive to leave in your oil. I simply add some to my tank of gas. Usually one to two cans a season.

I suppose adding it thru your vacume line would be a concentrated dose. Using it in your gas tank allows it to do it's job as your riding.

The instructions on the can say that it will treat 8 - 25 gal of gas or diesel, I put half a can in with the gas about every 90 days. Most people put it in their oil just before changing, but the sefoam websites says,

"To control moisture buildup in oil, add 1˝ oz. Sea Foam® to each quart of oil. Sea Foam® will prevent phase separation of moisture that accumulates in oil. Moisture will evaporate under the heat of the crank case. Change oil and filter when dirty."

That sounds to me like you can leave it in, but it would be up to you, I don't.

If there's nothing wrong with your bike and you've never used SeaFoam before, get a shot glass and add two shots (2oz.) to a full tank of gas. Do this every tank for awhile....(5-6 fill ups) then do it every other tank for a few more weeks, then just do it once a month. (depends alot on how often you fill your tank of course)

If you are having carb issues...drain your float bowls, then pour some down the fuel lines only, and put half the can in the tank. Let the bike sit overnight with the stuff in the fuel lines and carb before starting.

I just picked up 6 cans of it on sale at O'Reilly's, and already had one can. I have used a whole 16oz can in one tank of gas on the Vulcan without any issues. I also pull the fuel lines off the the petcock, drain the float bowls, and fill them up with pure Seafoam every 3 months or so. I turn the engine over with the starter to suck it up in the jets, then let it set for 24 hours, and drain it out. I have never had to remove my carbs to clean them in 72,000 miles.

Seafoam is also an excellent gas preservative. Again, use a whole can in one tank of fresh gas, and it will last over a year. Having gas in the tank makes it easy to start the bike up every week or two if you are storing it for the winter or whatever. Very bad for an engine to sit for too long without being moved.

The only time I have used it in the oil is when I buy a used bike that has not been properly maintained. I pour some in about 500 miles before an oil change, and change the oil every 1,000 miles until the engine is cleaned out and the new oil stays clean for awhile. I usually change the oil in the Vulcan every 1000 miles anyway, and the filter every 2,000 miles, using cheap Walmart SuperTech 20w50. If I'm going on a trip, I put better oil in it, but still rarely let it go over 3000 miles, even with the best synthetic in it. But yeah, Seafoam is some good stuff. And while it is on sale, I'd get at least 3 cans. It's buy 2 and get one free.

I am a motorcyclist, NOT a biker.
