Fuel quality is affected predominantly during its transport between producer and user as hired transporting companies may use one transport vehicle for more different fuels. Therefore, gasoline from previous transport may cause contamination of diesel fuel in next transport. Many drivers add gasoline as additive to diesel fuel to improve start of engine avoiding difficulties of cold winter temperatures. Therefore, the objective of this article is to assess maximum gasoline content added still compliant with default values of standard EN590 and values certified by producer. Only 2% maximal gasoline content in arctic diesel fuel was found safe for both machine and operator. Distillation curve, kinematic viscosity, density, lubricity and cetane index were influenced unimportantly. Cloud point, CFPP were not changed at all.
