Noble, answer me a question. . . . Since the standard for sulfur content for example for on road trucks is 15 ppm . . . and the maximum standard for aircraft fuel is 3,000 ppm. . . why the difference. . . ???? Also why do research where you test the visibility of combustion trails from aircraft where the sulfur content is 5,000 ppm. . . .???? Seems a waste of money and time to me. . . .don't you think. . . just inquiring minds at work here. . . .  First, you are simply wrong... The current upper value as stipulated by Defence Standard 91-91 and ASTM
D1655 is 3000ppm(m) whilst there is no mandatory minimum value. However, the
mean fuel sulphur concentration within the United Kingdom and the United States is
significantly lower than the stipulated maximum value and is about 600-800
ppm(m). www.easa.europa.eu/.../EASA_SULPHUR_Project_11-01-2010.pdf Secondly, sulphur content is low for road diesel as it kills catalytic converters... Look it up...
