1. Blockages in the oil circuit prevent the engine from working
There will be some moisture in gasoline. Some of this moisture is generated during the extraction process, while others are caused by external factors.
At normal temperatures, fuel can dissolve some water, but as the temperature decreases, the solubility of water correspondingly decreases, and the excess dissolved water will accumulate. Because the specific gravity of water is greater than that of oil, it will slowly separate and stay at the bend of the oil circuit or in the filter, causing fuel supply discontinuity. When the temperature is below the freezing point of water, it will condense and freeze, causing blockages in the oil circuit and preventing the engine from working.
When this phenomenon occurs, the common method is to pour hot water on the fuel tank and pipelines until the ice melts before starting the car to restore normal fuel temperature. However, this method is too time-consuming and labor-intensive, and may not be completely effective. Sometimes, it even requires dismantling the pipeline to remove the ice.
2. Moisture in gasoline can corrode and damage fuel system components
If the fuel system components are corroded and damaged by moisture for a long time, it is inevitable that there will be a "strike" phenomenon of damage. In this case, the corresponding components in the fuel pipeline must be replaced, and the entire fuel system must be cleaned to remove the moisture in the fuel in order to restore normal engine operation.
3. The fuel system pipelines are blocked by gum and carbon deposits
Entering winter, if the fuel system pipelines are not cleaned in a timely manner, the gum and carbon deposits in the pipelines will become dirty and clogged, causing poor fuel circulation, reduced fuel pressure, and premature failure of fuel filters.
