Number 1: Faulty Windshield Washer Fluid Can Cause Engine Damage

Introduction

Windshield washer fluid is an essential part of keeping your windshield clean and clear. However, there is a potential danger lurking in your windshield washer fluid reservoir that you may not be aware of. Certain types of windshield washer fluid can actually damage your engine.

What is the Problem?

The problem lies in the type of alcohol that is used in some windshield washer fluids. Methanol, also known as wood alcohol, is a common ingredient in windshield washer fluid. However, methanol is also a corrosive substance that can damage your engine's fuel system.

How Does Methanol Damage My Engine?

Methanol can damage your engine's fuel system by:

Coroding the fuel lines and fuel injector

Damaging the fuel pump

Causing the engine to run lean

What Type of Windshield Washer Fluid Should I Use?

To avoid the risk of engine damage, it is important to use a windshield washer fluid that does not contain methanol. Look for a windshield washer fluid that is labeled "safe for use on all vehicles."

How Do I Know if My Windshield Washer Fluid Contains Methanol?

The best way to determine if your windshield washer fluid contains methanol is to read the label. The label will list the ingredients of the windshield washer fluid. If methanol is listed as an ingredient, then you should not use that windshield washer fluid.

What Should I Do if I Have Already Used Windshield Washer Fluid Containing Methanol?

If you have already used windshield washer fluid containing methanol, you should flush your fuel system as soon as possible. To flush your fuel system, you will need to:

Fill your gas tank with fresh gas.

Add a fuel system cleaner to your gas tank.

Drive your car for at least 30 minutes.

Conclusion

Windshield washer fluid is an essential part of keeping your windshield clean and clear. However, it is important to use the right type of windshield washer fluid to avoid the risk of engine damage.
