In extreme situations, when available fuels are of poor quality or problems exist which are specific to certain operations,
additives can be used; however, the engine manufacturer recommends consulting 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 improve 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.
•
A lubricity enhancer can be used to increase the lubricity of fuels so that they meet the requirements given in
Table
24. Optional when operating temperature is below 0°C (32°F).
