What exactly does gasoline fuel additive do ?

For optimum fuel efficiency and lower emissions, fuel must first be atomized into a fine mist prior to entering the combustion chamber. Over time, injector deposits produce irregular spray patterns with heavy streams of gasoline that reduce performance, while intake valve deposits also decrease efficiency. By using a potent gasoline additive designed to clean combustion chamber deposits, intake valve deposits and port fuel injector deposits, improve fuel efficiency and performance will usually have a notable increase.
