I ran out of gas the other day (gauge has been reading off lately) and the tank-crud has filled the line and carb and it stumbles and sputters now. The tank needs to be replaced badly but I don't have the time until mid September to do it. I got some Seafoam after reading some threads here on FABO but wanted to get some first-hand advice from people that have used it before the EPA sends their SWAT team to my house (California). If I add it to the tank only will I still get the giant smoke cloud? Since this is my daily driver I don't want to drive my kid to school trailing a giant cloud of smoke. I get enough dirty looks for not driving a Prius here as it is.
