Bensínidísel

Bensínidísel is a colloquial term used in some regions, particularly in Iceland, to refer to a blend of gasoline (petrol) and diesel fuel. This mixture is not a standard or officially recognized fuel type by automotive manufacturers or fuel suppliers. Its creation and use are typically informal and often stem from situations where either gasoline or diesel fuel may be scarce or unavailable, or as an attempt to modify the properties of one of the fuels.

The mixing of gasoline and diesel is generally inadvisable. Gasoline has a lower flash point and is more volatile than diesel. When mixed with diesel, it can reduce the diesel's cetane number, which is a measure of its combustion quality. This can lead to poor engine performance, increased knocking or pinging sounds, and potentially severe engine damage due to improper combustion. Conversely, diesel fuel is a heavier, oilier substance and can clog fuel filters and injectors if mixed with gasoline.

The concept of fuel blending for alternative engines or specific conditions has been explored in specialized contexts, but the informal mixing of gasoline and diesel for regular use in standard vehicles is generally discouraged due to the high risk of mechanical failure. The term "bensínidísel" itself highlights this unusual and non-standard combination of two distinct fuel types.
