Find Out the BS 2869 Grade D Fuel Specifications<\/h2>\n\n\n\n

Crown Oil supplies red diesel<\/a> that meets Grade D within British Standard BS 2869<\/a>. Class D gas oil<\/a> is a 1000 ppm (parts per million) sulphur content gas oil. Therefore, this grade of gas oil is most widely used for heat generation but also for older static engines for power generation.<\/p>\n\n\n\n

Other grades of gas oil Crown Oil supplies include EN 590<\/a> red diesel. Within the BS 2869 standard, we also supply C1 class<\/a> and C2 class<\/a> of kerosene.<\/p>\n\n\n\n
