Diesel produced by various oil companies in Dubai is not dirty, unsafe, or bad. However, if you or the suppliers of it provide these conditions, then it can cause dirty diesel to form:
Dirty Storage Tank
As discussed earlier that even small contamination can cause serious problems. Similarly, leaving the storage tanks without caps or with loose caps can cause contaminants to enter them. The problem is so serious that even the fuel pumps cannot filter out the water and debris in the diesel supplier in Ajman.
Stale Fuel
Putting the diesel in a non-airtight container can also cause multiple problems. The gasoline becomes stale due to oxidation and weakened bonding between its molecules.
