paragraph_text: Storage and additives
  
  In the US, diesel is recommended to be stored in a yellow container to differentiate it from kerosene, which is typically kept in blue containers, and gasoline (petrol), which is typically kept in red containers. In the UK, diesel is normally stored in a black container to differentiate it from unleaded or leaded petrol, which are stored in green and red containers, respectively.
  
  Ethylene-vinyl acetate (EVA) is added to diesel as a "cold flow improver". 50-500 ppm of EVA inhibits crystallization of waxes, which can block fuel filters. Antifoaming agents (silicones), antioxidants (hindered phenols), and "metal deactivating agents" (salicylaldimines) are other additives. Their use is dictated by the particular composition of and storage plans for diesel fuels. Each is added at the 5-50 ppm level.
