In 2006, the U.S. Department of Transportation mandated coloring restrictions for diesel fuels. These coloring restrictions would have required Sea Foam Sales Company to separately package a diesel version of Sea Foam Motor Treatment without the familiar “Sea Foam Green” oil dye.

In a time when so many manufacturing cost increases are being passed on to the consumer, the Sea Foam Sales Company Management Team believed it was best to NOT further increase pricing by packaging a separate Diesel Product, when the only difference would have been the color. Therefore, as of November, 2006 ALL production of Sea Foam Motor Treatment is no longer being colored.

Other than the removal of the oil dye, Sea Foam Motor Treatment remains unchanged since its original formulation in 1940.

Thank You for being a loyal Sea Foam Products customer!
