Cold Flow Improver

Historically, No. 1 diesel was used to improve the wintertime diesel operability characteristics of pic40.jpgNo. 2 diesel fuel. If you’ve been doing this, it’s time to reconsider.

Over the last several years, many factors have changed, including:

  • Methods of extracting crude
  • Changes in refining processes
  • Reductions in allowable sulfur  content
  • Improvements in engine technology

But, perhaps the most significant advancement is our understanding of how wax particles in ultra-low-sulfur diesel (ULSD) cause winter operability issues and how we can control them through cold-flow chemistry.

Over the past seven winters at 15 terminals across the Midwest, No. 2 diesel treated with FS SURE-FLO™ was compared to a 70% No. 2 / 30% No. 1 fuel dilution. On average, the dilution with No. 1 lowered the CFPP of No.2 ULSD by only 5.5ºF. Meanwhile, a single treatment of SURE-FLO reduced the CFPP by over 20ºF. A double treatment of SURE-FLO reduces CFPP by over 27ºF. See the chart below.

Fuel treated with FS SURE-FLO outperforms No. 1 fuel dilutions with better economics and without sacrificing fuel efficiency associated with the lower BTU content of No. 1 diesel. Cold-flow improvers like FS SURE-FLO are clearly the better choice.
