What is the difference between B5 diesel and No. 0 diesel?
2 Answers
The specific differences are as follows: Different sources: B5 diesel is made by blending waste "gutter oil" from the catering industry and sewer systems with ordinary diesel in a ratio of 5:95 after a series of biochemical reactions. No. 0 diesel is produced through processes such as direct distillation or cracking of crude oil and shale oil. Different environmental impacts: B5 biodiesel can reduce emissions of heavy metals and fine particulate matter by more than 10%, with a nitrogen oxide purification efficiency of up to 80%. No. 0 diesel contains more impurities and tends to produce more soot when burned, leading to air pollution. Different scales of use: B5 biodiesel is currently only used in small-scale applications in some cities, but its production and usage will continue to expand. No. 0 diesel is a type of ordinary diesel, and diesel vehicles mainly use the latter five grades of diesel. When the temperature is above 4°C, No. 0 diesel is selected, so it is currently widely used.
I've been driving for over ten years and always have to consider which type of diesel fuel is more suitable. B5 diesel contains 5% bio-components, such as those made from vegetable oil, making it feel more environmentally friendly with lower emissions. However, it might start a bit slower in winter. As for No. 0 diesel, it's mainly used in areas where temperatures aren't too low, such as during spring, summer, and autumn when it's above zero degrees. It starts quickly and is just standard diesel. I often see No. 0 diesel at gas stations, and it's usually cheaper. B5 sometimes has government subsidies but may pose a slight long-term corrosion risk to the engine, requiring more frequent maintenance. When temperatures drop below zero, No. 0 diesel becomes thick and hard to start, while B5 performs slightly better but still isn't ideal. In short, you should choose based on the season and region—don't try to save money by using the wrong fuel in cold weather with the AC on, or you might end up stranded.
