Winter diesel fuel
Paraffin in the diesel tends to solidify, which results in clogging of the filter or the fuel and injection pipes, when very cold. This results problematic, especially in the start-up phase, so much so that to avoid it the oil companies distribute a special fuel to be used during the very cold season. This is denominated GP Diesel winter diesel, which is available in San Marco Petroli service stations from November to March. According to international standards, its use is guaranteed for temperatures up to -16 ° C (compared to 0 ° C for “summer” diesel distributed during the rest of the year).
Minus ten degrees is already quite cold, but in some mountain areas the thermometer often shows even lower temperatures. This is why “Arctic” diesel is distributed in service stations in the Alps and in the colder surrounding areas. The most extreme temperature is around -25 ° C
San Marco Petroli’s denatured diesel is a fuel specifically formulated for agricultural and marine purposes. From a fiscal point of view, it benefits from a reduced excise duty compared to traditional diesel and for this reason it is treated with a fuel dye that gives it a characteristic green color before its sale. Denatured diesel fuel complies with the European standard UNI EN 590, legal requirements and customs regulations. It does not contain metallic additives.
