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!
