I have used it without issue. just follow the instructions. change the oil very soon afterwards. it wets the spark plugs so a plug change is often recommended.
there is some videos on youtube of vettes being foamed just search it.
use the search feature on here. there are several threads on it.

Do it on a hot engine when using through the intake. I use the brake booster vac line to slurp in a third of a cup slowly. Car will start studdering to the point it wants to cut out. If car doesnt stall out then shut the motor off as soon as the vac line sucks it all through. Leave motor off 5 minutes then restart. Watch the smoke show. (This is a good sign that SeaFoam is doing its job).
Put the recommended amount in your oil (crankcase), drive it around no more then 100 miles then change oil. Old oil will look like black syrup.
Put some in the gas tank to help clean injectors. Some early C4's use injectors that will not respond well to SeaFoam. Make sure yours is not one of them.

I ran it through the intake and had a more responsive throttle for awhile, I think when I poured the rest into my gas tank It might have caused the sock on the end of the fuel pump to get sucked up into the pump and my fuel filter clogged up shortly thereafter? Again I don't know if the Sea Foam coated or deteriorated the sock material, but it was sucked up into the pump.

What is this oil changing thing about? I keep reading this about Seafoam but I can't seem to find it on the can. You can actually add it to your oil. Never heard of the plug changing either. That is one of the things it does is to CLEAN the combustion chamber. Why would you remove the plug to clean it after it has already been cleaned.........
Use the stuff it works pretty good for something in a can.

When questions come up like this one, I Like to pass along the experiences posted by other members on other Forums as I come across them. My intent is not to advocate of dis-advocate (is that even a word?), just to share.
Naturally, SeaFoam will claim it's safe; what else can they say and still expect to sell their product?
But on another Forum, a few days ago, I guy spun his bearings using SeaForm in his gas tank. As I recall his post, he added a can to his fuel tank, fired the engine and let it idle for a while. Then revved the engine a few times, his thinking was it would help distribute the Seafoam better.
Anyway, when he finished and shut down the engine, he had rod knock(s) and is now looking at an engine re-build. Now, rather he specifically followed the directions, I can't say, but that was his experience.
I believe it's posted on the camaroz28 or ls1lt1 if you want to track it down.
I'm just passing this along for those who're interested, so please, don't kill the messenger.

Similar situation happened to me. I switched to Synthetic Quakerstate oil. 1 week later, I spun a bearing....I wasnt idling. I was hitting the rev limiter in each gear racing a souped up SRT-4 so......
That was a couple years ago and I highly highly doubt that the oil change had anything to do with it.Ive used sea foam since I have owned my vette(6 years) and NOTHING bad has happened when using seafoam on it, nor on my pickuptruck...
Like Jake mentioned, nobody is guaranteeing you wont tear something up. I mean, if somethings going to break, it's going to break.
People flush old transmissions and they die the next day. People do one drag race and rip out there D36...
Hell, I might as well say your car is going to blow up when you add seafoam!

And if you have a 90s Corvette, don't add it to your gas tank. Multec injectors don't like cleaning agents....
P.S. DO change your oil if you pour it in the crankcase as the sea foam is dissolving build up and carbon and can break down your oil as well.

The only thing that sea foam could damage would be the fuel filter or injectors. If they are multec, aint no cleaning going to save them. They fail....not IF but WHEN....
As for the filter it "could" eat up/destory a worn out filter/sock but other than that, no damage could occur from using in the gas tank...
Now pouring sea foam thru the vacum line COULD hydrolock your engine...not common but could happen....Pour it in slowly and carefully and you should be fine. I have done it in all three areas numerous times and no ill effects.

I've used Seafoam for years in many types of powerplants. It's not caused problem #1. I always add it in the brake booster line, and change the oil directly afterwards; the plugs sometimes collect a little of the buildup that is loosened in the process.

I have cleaned out the vette engine a few times with it, and it did work well.
I put seafoam into my old trucks 350 sbc. I put it in the oil fill. ran it probably 10 miles tops. changed the oil, and in 4 miles I had a rod knock. I just wanted to clean it out a little since milage is unknown on it.
I dont use seafoam anymore.
Still have to rebuild the truck engine, or replace.
