I haven't really looked into it... but I'm thinking premium gas should be the only thing entering the tank. EnviroTab makes a claim about carbon building up in engines. If you have carbon building in your engine then you got other issues that a pill is not going to solve. If you are looking to add power then look to the mod section on this website. If you are looking to save on gas then sell the car and buy a moped. That EnviroTab is a scam. Save your money.
