Some of the sulfur compounds naturally occurring in diesel fuel provide some wear protection or lubricity. To compensate for the sulfur removal in ULSD Mobil branded diesel fuel is treated with additives to improve lubricity. Customers can be confident in choosing Mobil because our branded ULSD fuel meets ASTM D 975 diesel fuel specifications, which provide standards for lubricity, cetane number and other performance characteristics.
