6.3 Fuel Specifications

Follow the specifications for fuel quality to optimize system performance and prevent damage to the engine or fuel
components.
Use only ultra low sulphur diesel (ULSD) from a reputable supplier. For most year-round service, No. 2 ULSD fuel meeting
ASTM specification D975 Grade S15 will provide good performance.
If the vehicle is exposed to extreme cold (below -7°C [20°F]) or is required to operate at colder-than-normal conditions for
prolonged periods, use climatized No. 2 diesel fuel, or dilute the No. 2 ULSD fuel with 50% No. 1 ULSD fuel. This will
provide better protection from fuel gelling or wax-plugging of the fuel filters.

In extreme situations, when available fuels are of poor quality or problems exist which are particular to certain operations,
additives can be used; however, the engine manufacturer recommends consultation with the fuel supplier or engine
manufacturer before using fuel additives. Situations where additives are useful include:
• A cetane improver additive can be used with low cetane fuels.
• A wax crystal modifier can help with fuels with high cold filter plugging points (CFPP).
• An anti-icer can help prevent ice formation in wet fuel during cold weather.
• An antioxidant or storage stability additive can help with fuel system deposits and poor storage stability.
• Diesel fuel conditioner can be used to increase the lubricity of fuels so that they meet the requirements given in
Table 6.1, page 136.
