Did the smoke that came out smell nasty, like carbon burning, or have more of an oil burning smell? I think the seafoam itself will also cause smoke, but you can tell when it's carbon burning.
Honestly, I didnt notice much difference after I did the treatment. The seafoam definately got rid of some carbon bulid up in the engine, I could smell it in the smoke. There was not as much smoke as I thought there would be but I am happy about that.
I also used seafoam on my stepsons 93 Bronco with 155000 miles on it. It really made a difference in his car. LOTS of smoke and nasty carbon smell. Ran smoother also.
I would recommend seafoam for higher milage engines for sure. With all the detergents in todays gas it would probably be ok to wait for much higher milage before using seafoam. Seafoam recommends using the product every 2-5000 miles but that seems a bit excessive to me. If you just want the peace of mind knowing that your engine is super clean than you should definately use it.
