What’s the Deal With Red-Dyed Diesel Fuel?
The sulfur content in diesel fuel is something many people tend to overlook, but be careful! You don’t want the sulfur content in your diesel to be any higher than 15 ppm if you’re using it in your standby generator.
The EPA requires red dye in diesel fuel with a high-sulfur content. The purpose for this was to make sure it’s not used in on-road vehicles.
The IRS requires red dye in diesel fuel that’s tax-exempt to make sure it’s not used for taxable purposes.
However, by October of this year, the EPA is going to require that any tax-exempt, red-dyed diesel fuel have a sulfur content less that 15 ppm.
If you’re careful, you can already find tax-exempt red-dyed diesel fuel under 15 ppm, but having it all switch over may motivate generator owners to start shopping differently to save money.
Generac States: “The standby generator owner/operator is solely responsible for identifying the sulfur content of the diesel fuel used in their generator, ensuring the fuel purchased does not exceed the 15 ppm sulfur limitation.”
