Notes:

  1. High sulfur diesel must be dyed at the refinery (EPA regulations) to a visible pink color. According to IRS this fuel must contain Dye Solvent 164 at a concentration spectrally equivalent to 3.9 pounds per thousand barrels (PTB) (11.13 mg/liter) of solid dye Standard Solvent red 26. Low sulfur, ultra low sulfur and CARB diesel are generally on road diesels and consequently not dyed. However, if they are sold as non-taxable diesel or heating fuel they must be dyed to 3.9 PTB.
  2. The Kinder Morgan Pipelines and the Chevron Pipelines have a minimum 30 API gravity specification.
  3. 125 ºF flash point minimum is for vehicles. Some marine fuels and utility companies require a 140 ºF flash point.
  4. CARB regulation limits the aromatics to 10 volume % maximum. CARB also permits the use of a CARB "alternate diesel" formulation. CARB alternate formulations specify the sulfur, cetane number, aromatics, nitrogen and poly nuclear aromatics levels. The supplier must certify that the diesel is per Title 13, California Code of Regulations, Sections 2281 and 2282. Aromatics content method D1319 has poor reproducibility with diesels. CARB allows the use of the more precise D5168. CARB "alternate diesel formulas" must report aromatics in mass %.
  5. D4737 may be used in lieu of D613 however; D613 shall be run at intervals to assure compliance. CARB approved "alternate diesel formulas" must be tested by D613 and meet the minimum cetane designated by the CARB certification formula for that fuel. D4737, procedure A is applicable to high sulfur diesel and procedure B is applicable to low sulfur and ultra low sulfur diesel.
  6. D976 is a substitute allowed by EPA in place of testing for aromatics. It is not a substitute for D613. For cetane index, D4737 must be used.
  7. Both low sulfur (S500) and ultra low sulfur diesel (S15) are legal on-highway fuels through June 1, 2010 outside of California. Inside California only CARB ultra low sulfur diesel is allowed for al l vehicle diesel (on and off road) and stationary equipment. Also see note 4 for California diesel.
  8. If the supplier uses a different test method for determining stability, the fuel must meet an equivalent specification. We reserve the right to reject fuel as not "fit for purpose" that does not meet this specification.
  9. During the winter, field blending of with number one grades may be necessary to reach the desired cloud point in a certain location. When the cloud point is less than 10 ºF, the minimum flash point can be 100 ºF, the minimum viscosity 1.7cSt, and the minimum 90% recovered is waived.
