Modern consumer vehicles (non-diesel) are all equipped with a rather uniform fuel system in which has many critical components that are susceptible fuel contaminants. Most vehicle owners have heard of the “quarter tank syndrome” in which it is recommended that you not run your vehicle with a quarter tank or less of fuel. Why is this? It is partially to do with cooling/lubrication, however, mostly to prevent the small particulates found in fuel from entering your fuel system. Small debris can mix in with the fuel during production, transportation, and during introduction to the fuel system (vehicle tank). Countries such as the US currently have regulated filters throughout the process, including at the pump, however, none of these are effective enough to prevent particulates from entering the fuel system. The evidence is seen in the fuel system failures resulting from the contaminants. According to studies, one of the leading causes of the following fuel system failures is due to particulates in fuel resulting from the refining and transportation process or accidental insertion (dirt, paint, etc. knocked in during fueling).
