Seafoam

I just talked to one of my friends and asked him about SeaFoam, which I had purchased today. He didn't know what it was, so I told him and he said that adding it through the brake booster/PCV valve wasn't a good idea, as it would remove carbon buildup on the inside of the cylinders, causing it to create problems in the future. He said he also didn't recommend adding it to the oil either. I was just wondering if anyone could either verify this or add any other concerns that I should know about. Thanks. Info under this post, except it's now at 327500kms (about 205000miles).

I have not tried it, however on other forums for my Volvo and Ducati motorcycle they recommend using it. The Volvo forum claims it smooths rough idle among other things. The one thing I did notice is that they claim to never use the brake booster line. Find another vac. line to use. I am planning to use it on all three vehicles. But be prepared for the smoke show. I hear you will not make any friends. It looks like a small brush fire.

I always go by the old rule of the best additive is no additive and if it is not broke do not try to fix it.
Unless you have a bad carbon build up leave it as is.
And do not add it to the engine oil.
Sea Foam was made for a gas stabilizer.
It is a Good gas additive for winter or long term storage.
GAS AT THE PUMPS WILL HAVE THE PROPER ADDITIVES YOU NEED ALREADY IN IT.

I have used Seafoam in my 1999 Suburban with great results, Two cans in the gas tank (44Gal) and one in the oil. These motors have problems with sticky valves and this takes care of that. Try it you'll like it.
