ULSD runs in any engine designed for the ASTM D975 diesel fuel, however, it is known to cause some seals to shrink, [8] and may cause fuel pump failures in Volkswagen TDI engines used in 2006 to pre-2009 models. [citation needed] TDI engines from 2009 and on are designed to use ULSD exclusively; biodiesel blends are reported to prevent that ...
In North America, gas stations offer two types of diesel fuel – according to ASTM D975 [5] these are named No. 1 and No. 2 fuel. No. 1 fuel (similar to kerosene) has a natural CFPP of -40 °C but it is more expensive than No. 2 fuel. Adding No. 1 fuel will lower the CFPP of No. 2 fuel – adding 10% will lower the CFPP temperature by about 5 ...
Whether as an admixture or in its pure form, the fuel is able to supplement or partially replace conventional diesel without problems. Neste guarantees that every gallon sold meets ASTM D975 and EN 15940 specifications in compliance with OEM standards. [1]
The cetane number of a fuel is defined by finding a blend of cetane and isocetane with the same ignition delay. Cetane has a cetane number defined to be 100, while isocetane's measured cetane number is 15, replacing the former reference fuel alpha-methylnaphthalene, which was assigned a cetane number of 0.
ASTM International has approved a new specification for diesel fuel blends containing 6%-20% biodiesel. According to the National Biodiesel Board (NBB), ASTM standards for the 20% biodiesel blends, or B20, are a crucial hurdle for the full acceptance of the use of such blends in diesel vehicles. In 2008, ASTM published new Biodiesel Blend ...
Generally, diesel engines operate well with a CN from 40 to 55, whereas LS9 UltraClean has a CN of 70. In North America, most states adopt ASTM D975 as their diesel fuel standard and the minimum cetane number is set at 40, with typical values in the 42-45 range. In Europe, with a minimum cetane index of 46 and a minimum cetane number of 51.

The EN 590 had been introduced along with the European emission standards.With each of its revisions the EN 590 had been adapted to lower the sulphur content of diesel fuel – since 2007 this is called ultra-low-sulphur diesel as the former function of sulphur as a lubricant is absent (and needs to be replaced by additives).
