What causes foam in diesel?
Thread Content
Dear experts: Why is there so much diesel foam? In a semi-truck that can hold 300 liters of diesel, it’s no longer possible to add more fuel after 50 liters have been poured in – it’s all due to the diesel foam. Thank you. This post was last edited by Shuichangshou on 2009-3-3 at 19:24
What you added is not diesel that has been properly processed in a refinery; our regularly produced diesel products do not contain diesel foam.
Qualified diesel should not produce foam.
The diesel you added is definitely not a qualified product
It’s diesel produced by a fairly large factory in Shandong
It might not meet the standards; is the analysis satisfactory? ? Was the flow rate too fast during loading? ?
Did you fill it up at a legitimate gas station? Some stations tamper with the products to make them appear qualified; it is recommended that the original poster go to a proper gas station.

The fuel flow rate is too high, or the gun has static electricity and is not properly grounded. . . Diesel has a high boiling range and high viscosity. . . So the charging speed cannot be too fast. . . Maybe the gas attendant doesn’t know very well how to fill up with diesel. . . Some gas stations are lazy and let drivers insert their own cards to refuel, whereas those drivers often lack proper training in fueling. . . Haha. . :lol
Qualified diesel will dissipate foam quickly even when flowing at a fast rate, but since 300L could be added yet only 50L was used, the problem likely lies with the diesel itself.
I bought the diesel from an oil company
If there’s a problem with your fuel tank, then it must be an issue with the quality of the diesel – it’s possible that additives have been added to it, or that it contains a small amount of water.
Foam in diesel is caused by illegal vendors adding water and emulsifiers
Is it because the freezing point or cold set point is not reached, causing the diesel foam to dissipate more slowly due to low temperatures?
Is the dew point of diesel too high, and is its viscosity high?
