Can I use too much? Can I leave it in the tank along with fuel stabilizer for storage?
 
Yes and yes

How much is too much? From the other threads I read on here you want the highest concentration possible to make it actually clean anything in the fuel system. If you're using it in your oil you obviously wouldn't want to use too much.
 
The recommendations are 1oz per gallon of gas. Generally around 1/3 can per tankful.

Ok I've always heard to ignore that recommendation. Maybe I'll start following it. I've run both my car and my bike off of almost entirely Seafoam before and never had any issues beyond lots of smoke.
 
I put one can of Seafoam into the gas on my car before storage, and after it comes out of storage with no issues.

Last time I used it I put 3 cans into my RS125 on a nearly empty tank of gas right after I got it. Only downside was it smoked up the whole neighborhood when I started it. Ran that for a day or two before filling the rest of the way with gas. Got really good fuel economy (about double what I expected to get) but I haven't used a 2nd tank in it yet due to the cold wet weather so I'm not sure if it'll be normal or not.

.. wait till you put some in a car through a vaccum line that has some good mileage on it.

You havent seen a smoke show yet .. lol. I tried it on my old dakota, let it run for 5 minutes and shut it off. Came out and fired it back up 30 minutes later, and the neighbourhood thought my house was on fire.

Coworker got another coworker to help him do that on his older Jetta. The guy doing the helping didn't realize that "let it slowly sip from the can" didn't mean "let it suck back half the can at once". It stalled out and once he got it started again it smoked like crazy.

Then they did the other guy's newer A3 and they did the same thing but the A3 just sucked it all back with no smoke, stalling, or drama.

Anyone ever used Seafoam in a two stroke? I wanted to put it in my old two stroke snow blower but wasn't sure if it would hinder the lubrication or benefit it.

The can and my Googleing said it was great for 2 strokes. The bike I put 3 cans into at once is a 2 stroke. Sure smoked a lot, though.
