How to Solve Fuel Water Contamination Fault?

The solutions for fuel water contamination fault are: 1. Clean the fuel tank and fuel lines; 2. Replace the engine oil and oil filter; 3. Inspect and replace the fuel pump, fuel injector, cylinder, and exhaust oxygen sensor; 4. Add high-quality engine oil. The impacts of fuel water contamination are: 1. Damage the oil film, reduce lubricity, and increase wear on friction components; 2. React with oil to form acids, gum, and sludge; 3. Dilute gasoline additives and reduce performance; 4. Cause cavitation at the pump inlet or other low-pressure areas under high temperatures; 5. Lead to sticking of control valves, resulting in delayed control response; 6. Poor fluidity at low temperatures.

I've been repairing cars for over a decade and have dealt with numerous fuel water contamination issues. The most common scenario is water accumulation in the fuel tank, which could result from using substandard gasoline or condensation buildup. Symptoms include engine shaking, poor acceleration, or even stalling. The first step is to stop driving immediately and park in a safe location. Solutions vary by severity: For minor cases, adding a bottle of fuel dehydrator to the tank can absorb the moisture; for serious contamination, you'll need to drain the tank, remove all water, and clean the fuel lines—the fuel filter must be replaced to prevent clogged injectors. Prevention is straightforward: always refuel at reputable stations and avoid prolonged parking in damp areas. During routine maintenance, request fuel system inspections, especially during southern rainy seasons—installing water-separating devices in advance is highly effective. Considering the substantial repair costs for water-damaged engines, spending a little on prevention is absolutely worthwhile.

Last time I was on a business trip, I ran into this annoying issue. The car suddenly started shaking like it was dancing, couldn't pick up speed even with the pedal to the metal, and the dashboard lit up with warning lights. After towing it to the repair shop, the mechanic said it was caused by water-contaminated fuel. He explained that water can get into the fuel tank either from condensation in gas station storage tanks or from refueling during rainy weather. The solution was pretty straightforward: drain the fuel-water mixture from the tank, replace the fuel filter with a new one, and fill up with fresh gasoline. I picked up a handy tip myself - adding a water remover before long trips as a preventive measure. Now I only refuel at major chain gas stations and avoid smaller ones. Remember not to wait until the fuel light comes on; keeping the tank at least half full helps reduce condensation. After adopting these habits, I haven't had any issues for two years - much more peace of mind.

As a seasoned car enthusiast, I've researched fuel water contamination issues. The essence is that water, being denser than gasoline, settles at the bottom of the tank and corrodes metal components. The diagnostic methods are straightforward: difficulty in cold starts and white steam-like smoke from the exhaust. For treatment, I've tried three approaches: using ethanol-based water removers to separate small amounts of water; dismantling and cleaning the fuel pump filter screen for moderate cases; and in severe situations, draining the fuel and replacing the entire fuel filter assembly. For prevention, I've upgraded to a filter with a water sensor and regularly test the bottom tank liquid with test strips. Additionally, avoid directing high-pressure car wash jets at the fuel tank cap and park away from low-lying waterlogged areas. These details can effectively extend engine life, especially crucial for direct injection models.
