I used it in the gas,but never tried the mix it in the oil method yet.

 

A friend of mine had a lifter sticking on a 600, put 2 ounces of seafoam in the oil, ran it awhile and it freed the liofter, also made clean oil look like diesel oil, thats how much it cleane the engine, Im gonna do it to my old 425 next time its due.

 

ok since everyone's using it...


how much do you add to the gas and how often?
how much do you add to the oil, and how long before the oil change?

 

Going to have to pick me up a can.
Like rugnuts said. How much do you add?

 

Got a 20 gallon tank on my Ranger and I use the whole can in it. I've poured about 1/3 of a can directly into the throttle body while the car was running on my sister in laws car. The Ranger is side draft, so I put it in a spray bottle I got at the dollar store and spray it in while it's running. For the motorcycle, I usually just count to 3 while I'm pouring. Your methods might not need to be so scientific. Same thing on the quads.

Cars and trucks I'd say I use it about every other month. Bike is about every third tank. Quads are when I'm getting ready to store them, and make sure the treated gas gets to the carb, and when I can remember when we go riding.

 

One second for every gallon of gas is a pretty non scientific way to add additives

 

Well, it's not rocket science. I got a digital watch for that.

 

Picked up can at lunch today cant wait to see how it works.

 

Seafoam is so amazing, it delivered my second child...the stuff is gureaat. I want a Seafoam shirt damn it. haha.

In the oil, 1.5oz per qt of oil. My atv's take 2 qts. so 3oz in the oil. I usually put some in my oil the last 2 hours before an oil change. I don't leave it in the oil too long.

In the gas...I think I put 1/3 (or 3 seconds lol) can in with a full tank. A whole bottle treats 8-25 gallons.

 

LOL!!!!
