I don't too. There is no data to prove that. There is only one product with record track and enough data, to qualify it has a "fuel saving" product. It's a fuel re-formulator with 288 ester on mineral oil base that clean and lubricate the combustion chamber. A clean combustion chamber will burn the mix of air and fuel more efficient resulting in more MPG. To know more about this fuel re-formulator, please visit http://www.4-ecorp.com/gmartinez
