I can't really tell you any cons! Seafoam is great and I would highly recommend it between tune ups. All that smoke you see coming from the exhaust is just the carbon being dissolved. I am not a fan of adding solvents to the crank case so I personally do not add it to the oil. I always add it to the intake and the fuel though. Works great.


Was there ever a time where your car didn't start after putting it in?


No, never. While putting it in your engine it is completely normal for the engine to wanna sputter out but it has always stared right back up for me.


My Mark VII has the same 5.0 high output as your t-bird. Great engines!! Never had a problem with them while using seafoam.


Go to YouTube and search for "bad seafoam". I found 150 videos of bad results.


Ok cool thanks a lot. I'll try some out!! Oh and yes the engines are fantastic!!


And tenspeed thanks I will look them up.
