Snake Oil. I think it's just alcohol, naptha and some other mineral spirit. I've heard people swear by it. I've tried and never noticed anything.

I just tried it on my street bike hoping it would unplug a gunked up carb....No go. It didn't do crap. Looks like the carb is coming off for a cleaning, which really sucks on a inline 4 sportbike.

It's essentially a cleaner, and it does have fuel stabilizing properties. I use a half cup or so in every 5 gallon can I buy, (unless we're goin ridin, 5 gallons gets old fast) and I don't see the starting problems with the lawnmower anymore. Since I have started this practice, I don't see the gumming problems that I used to in engines that get used very little.

It will clean minor amount of residue, but it's not a cure-all, and should never be used to replace a good cleaning and inspection.

It works great for cleaning carbon deposits from the combustion chamber on your car or truck. I use it about every 15,000 to 20,000 miles. Start with a cold engine. Remove the vacuum line going to the brake booster and stick a funnel in it. Start the engine and slowly pour the S/F into the funnel. You will have to give it a little throttle to keep it running. This will suck the Seafoam straight into the cylinders and will remove a lot of the carbon. Be warned, your car/truck is going to smoke for a few miles after doing this. The engine should seem to run smoother.

I looked it up. It's Isopropyl alcohol (rubbing alcohol), pale oil and naphtha. If it works, great, but.....

I use it every 10,000 miles. I let the engine reach operating temp. Then I use the break booster line to suck in about 8-10 ounces of seafoam until the engine dies. I let it sit for about 5-7 minutes, start it up, and run the dog pi$$ out of it for about 10 minutes. Then change the oil. I pour the remaining seafoam into the gas tank......

don't use the tranny additive in an automatic tranny. I've heard from mechanics that it destroys the fluid, it works fine in manuals (haven't tried it) but breaks down the automatic tranny fluid....

I use the gas additive in the tank only all the time...about once a month with a full tank nothing beat real maintenance though.
