Does adding some windshield washer fluid to the gas tank have any impact?
2 Answers
If a very small amount of windshield washer fluid is added to the gas tank, the impact is minimal. Since water is denser than gasoline, it will settle at the bottom and not affect the vehicle. However, if a large amount of windshield washer fluid is added, the gas tank must be thoroughly cleaned. Functions of windshield washer fluid: Anti-freeze properties: The presence of alcohol and ethylene glycol significantly lowers the freezing point of the liquid, providing anti-freeze effects and quickly dissolving frost. Anti-static properties: After cleaning with windshield washer fluid, substances adsorbed on the glass surface can eliminate static charges on the glass, providing anti-static benefits. Precautions for adding windshield washer fluid: Vehicle-specific characteristics: Each vehicle has different requirements for windshield washer fluid. Factors such as concentration, molecular weight requirements, and pressure capacity must be understood to use the fluid effectively. These specifications are usually outlined in the vehicle's user manual, which may also include details about the electrical circuits in the wiper system. Only after confirming the vehicle's requirements can the next steps be taken. Selection and use of windshield washer fluid: After understanding the vehicle's requirements, choose a suitable windshield washer fluid. Many manufacturers offer pre-mixed fluids tailored to specific vehicle models, which can be added directly. If not available, you may need to purchase and mix the fluid in the correct proportions. When filling, avoid overfilling—top up as needed. Additionally, try to stick to the same brand to prevent clogging in the system. Temperature considerations: In colder climates, especially during winter, choose a windshield washer fluid with anti-freeze properties. Homemade mixtures may freeze, so drivers in northern regions should opt for ready-to-use anti-freeze solutions.
A friend of mine just experienced this a few days ago. It's definitely not okay to mix windshield washer fluid into the gasoline tank. Windshield washer fluid contains alcohols and detergents, which can disrupt the combustion performance of gasoline if directly added to the fuel system. If the amount is small, you might only experience engine shaking and weak acceleration, and driving a few dozen kilometers might not be a big issue. However, a large quantity can be dangerous, potentially causing fuel injector clogging or even ruining the catalytic converter. Remember, do not attempt to start the engine. Call a professional tow truck to take your car to a repair shop for a thorough cleaning of the fuel tank and fuel lines. The mechanic mentioned that cleaning the fuel lines alone would cost over 800 yuan—quite a hefty price for a simple mistake.
