Can No. 0 Diesel and No. 35 Diesel Be Mixed?
2 Answers
No. 0 diesel and No. 35 diesel can be mixed. The relevant introduction about diesel grades is as follows: Basis of diesel grades: The basis of diesel grades is the freezing point of diesel. For diesel of the same grade but different numbers, since their quality indicators are basically the same except for the freezing point and cold filter plugging point, diesel of different grades can be mixed for use. However, mixing will increase the freezing point temperature of No. 35 diesel. When changing diesel grades in a low-temperature environment, it is necessary to clean up the original oil before adding No. -35 diesel to ensure that the diesel vehicle can start normally at low temperatures. Precautions: Diesel is a dangerous substance that is prone to burning and explosion. Its auto-ignition temperature is 335 degrees Celsius, and it has a high calorific value after combustion. Once a fire occurs, the fuel will vaporize in large quantities, causing the fire to spread rapidly and making it difficult to extinguish. Therefore, reasonable fire prevention and explosion-proof measures must be taken during use to ensure safety.
I've been driving trucks for over a decade and have quite a say about diesel types. No. 0 diesel is regular diesel with a high pour point, prone to solidification in cold weather; No. 35 diesel is low-pour-point diesel, more suitable for use in frigid zones. Mixing them can lead to unstable overall pour points, potentially causing the fuel to thicken when temperatures drop, clogging filters or injectors. Once during a business trip up north, I mixed a bit and ended up unable to start the engine in the morning—had to tow it to the repair shop, costing me over 500 bucks for nothing. Long-term mixing may also result in incomplete combustion, increased carbon deposits, and shortened engine life. So, it's best not to mix fuels; always check the label when refueling to choose the same type, and switch to low-pour-point diesel before cold weather hits for safety and peace of mind. This way, you drive worry-free and save money.
