214733 248 Revision A
5.1.2 Fuel Specifications
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
5.1, page 248 . Diesel fuel conditioner is available from your Dealer.
