This week's executive order lets red-dyed diesel run on public highways through December 31.
Dyed diesel is the identical fuel. The red dye marks it as exempt from the federal highway tax of about 24 cents a gallon, because it is meant for tractors and construction equipment that stay off public roads.
A 250-gallon fill saves roughly $60 on the federal portion alone.
