Author Topic:   Proper Color Of Smoke From The Engine of A Motor Home With Sea Foam In Fuel

[I] put some [Sea Foam] in the gas tank of my motor home. What color is the smoke is supposed to be?
[I] went through 20-gallons of regular gasoline, filled the tank back up, figured that by filling the tank with fresh gas the smoking would stop, but, after driving 50 or so miles, it is still smoking. [I] don't know if [I] did more harm than good on this one. [I] added [Sea Foam] because [I] have read and heard a lot about it on different web sites. [Y]our response would be greatly appreciated. [T]hanks. And have a nice day.

No harm done/ The exhaust system on your motor home and the muffler holds a huge area of fuel carbon. The age and mileage of your home determines the amount of build up in your system, and regular treatment will remove the build up and than keep it clean. If your motor is fuel injected you might try a garage that does an injector cleaner service, and ask if the will run a can of Sea Foam through it, let the home sit for about two hours, and then drive slowly on some back roads for an hour or two.

Yes, but what color is the smoke supposed to be?

My experience with Seafoam has been black smoke when carbon is present in the engine and exhaust. As the carbon is removed the smoke will be white.
Hope this helps.

Not white. That would indicate steam.

No it is white Pete. Go on Youtube and watch. People(kids usually) think it is fun to put it in their tank and cruise around like a DDT sprayer.

You don't want BLUE smoke from the exhaust of your motor home - that indicates that you are burning oil. You don't generally want white smoke that dissapates (steam) as that indicates a cracked block that is letting cooling in.
If your exhaust is emitting white smoke that doesn't dissapate, that is a 'normal' observation when using Sea Foam and/or fogging oil.
How long it will smoke is determined by a number of factors. The biggest question is how was the motor running before the sea foam application - i.e. why did you add it?
Because your exhaust system is very long and can contain a great deal of material (carbon) along it's length, it is possible that you will experienced prolonged smoking from treatment. Also, you may have a great deal more carbon build up if your motor home is powered by a diesel motor.
If it has been a long time (like, never) since your last sea foam application and you have many miles on the motor (and short trips), there could be a significant amount of carbon in the system and it will take multiple treatments to clear it out.
In general, I run sea foam in my truck once a year in the "middle tank" during a long trip when the engine is fully warm and I'm running at pretty good RPM for prolonged periods.
I run stabilizer/sea foam in my boat tank constantly as a fuel stabilizer, EXCEPT on long trips where I know I will quickly use the fuel that is in the tank.

I agree with Tohsgib, we use to pour marvel oil, carb cleaner in the carb equals white smoke, Black smoke your engine is not running correctly, blue smoke means you are burning oil( from the piston rings, valves). I still pour some mavel oil in my tanks around every 15000 miles... Take Care

Black smoke is fine...with a diesel.
