Is it normal for vehicle to smoke after adding Sea Foam to fuel? [SOLVED]
Asked by Janet B. In Oklahoma
I drive a Chevy S10. Evidently I put some bad gas in the tank. I was told by a mechanic to add a full can of Sea Foam Motor Treatment to a full tank of gas, which I did. Now it smokes like a freight train. Is this normal or do I need to drain the tank?
Hi Janet – thanks for checking in. Typically, when Sea Foam Motor Treatment is added to gasoline the mixture is too low to cause noticeable smoking out of the tailpipe. I don’t think what you’re seeing is Sea Foam unless you had a very high concentration in fuel (1:1), which would emit visible oil vapor (Sea Foam is oil). I’d give it some time and see if the smoke diminishes as you burn off the fuel, or check back in briefly with your mechanic. Hope that helps!
