Well guys I did the sea foam in my 04 Ranger and got nothing. No smoke, but it feels like it runs a little smoother. I also used it on my girlfriends car which has 150,000 miles on it and got nothing with it either. WTF? I know its probably a good sign but It would have made me feel better to see something, you know see that it is actually doing what it is supposed to instead of hoping it did. I thought for sure the GFs car would smoke. Im kinda dissapointed....I wanted smoke!

 

my truck had 72k on it when i seafoamed it....very little smoke. Yet on my buddies '98 Escort, w/ 140k, it smoked like a sob.

 

I had 56k miles on mine and it only smoked when i got on it when i would be driving.

 

did it through the vac line, after waiting 15 minutes and starting it, i got a lot of smoke.

 

thats what i did. half in the tank and the other in the vac live.

 

**** mine had like 20K and smoked like a ****!

 

if u added it to the oil and it smokes, u got bigger problems to wrry bout. but if u add it to the gas and it dont smoke, just means your truck doesnt release any harmful emissions...

 

I think it has alot to do with how it was driven.

 

did mine at 55,000 miles. little smoke, big improvement.

 

I did mine at about 140k miles and I got some smoke, but not alot, mainly when I revved it. I think it the place I bought it from said it was all highway miles, so im sure that kept carbon from collecting as much, plus, the engine usually sees 5-6k rpms at least once every trip.
