And here we go again! LoL

Full can in the tank, 1/2 can in the TB (see you tube video), 1/2 can in the crank case. Change oil 300-500 miles later.

My answer is it won't do any harm in the gas tank once a month and will help with lessening carbon gunk buildup. I personally have experienced a + 1 1/2 MPG by adding a can of B12 and 8oz of isopropyl to a tank. Also expereinced xtra HP 15 minutes later. When I want to smoke the rear tires I add a can of B12. Just me talken. LOL

Seafoam is the stuff to use. I have some in my tank right now and its like night and day in response. I have used it and B12 over the years with no harmful effects at all.

I just seafoamed my truck like 6 hours ago and I was amazed by the results, I put half in my gas tank and sucked the rest through the vacuum line on the brake booster.

I've seen posts about where to put it, and there's about 6 different places to do so. From what I can tell you do the vacuum hose thing at the brake booster, in the gas tank, maybe spray the TB, and some people say in the oil. Is that right? Am I missing anything?

I've used that stuff in my lawn and snow equipment for years. I run it through my small engine equipment a couple times a year, the stuff that takes mix gas, because that stuff gets gunked up so easily. It works on that equipment nicely.

You can see my method in my post above... I offer anyone to drive my truck with 166K (owned since 78K) on factory plugs (I believe), etc... Super smooth idle and runs better than it did when I bought it. I perform this regimen every 20K miles or so... I thanks Seafoam for my trucks great high mileage performance!

I did the seafoam trick today. 1/2 in booster intake 1/2 in tank. No smoke at all?

You either let it sit too long or you did it wrong.

What are the safest instructions for just putting it in the gas tank? I am abit scared to put stuff into my engine hah but do I turn in on and let it warm up then pour it in my tank and let it sit and then wouldn't I have white smoke coming out until I burn off the tank?

If you just put it in your gas tank, their will never be a high enough concentration to produce the white smoke.
