What Happens if You Fill Your Power Steering Pump Full of Motor Oil?
Filling your power steering pump with motor oil instead of the recommended power steering fluid can lead to several issues. This practice not only voids the warranty but also significantly impacts the performance and longevity of your vehicle. In this article, we will explore the potential problems, the importance of using the correct fluid, and the steps you should take if motor oil has been mistakenly added to your power steering system.
Compatibility Issues
Power steering fluid is specifically formulated to work with the hydraulic components of the steering system. Motor oil may not have the right viscosity or additives to maintain proper lubrication and performance. This can lead to a variety of issues, from reduced efficiency to system failure.
Compromised Fluid Flow
Motor oil can create foam when subjected to the conditions in a power steering system. This foam can cause air bubbles that hinder fluid flow and reduce the effectiveness of the steering system. Proper fluid flow is crucial for the smooth operation of the steering mechanism, and any disruption can lead to harder steering and decreased handling.
Seal and Hose Damage
The additives in motor oil can be harsh on the seals and hoses in the power steering system. Over time, this can cause leaks or failures, which can be costly to repair. Seals and hoses are designed to handle the specific properties of power steering fluid, and using motor oil can degrade these components, leading to a myriad of issues.
Reduced Performance and Potential Damage
When motor oil is used instead of power steering fluid, you may experience harder steering, increased noise from the pump, or even a complete failure of the power steering system. This not only makes it difficult to control your vehicle but also poses a safety risk. Additionally, prolonged use of motor oil in the power steering system can lead to significant damage, requiring costly repairs or even replacement of components.
Real-Life Examples and Tips
The compatibility and performance issues mentioned above are not just theoretical. The viscosity of the motor oil can vary significantly, affecting its suitability for the power steering system. For instance, a 0W-20 motor oil might work without causing immediate damage on a belt-driven unit, but anything more viscous can increase the load on the pump and cause problems. In electric/hydraulic systems, even a 0W-20 might bog down the system and overtax the pump.
Many car enthusiasts have experienced the consequences of using motor oil in the power steering system. Using 15W-40, a high-viscosity oil, can lead to stranded vehicles and the need for a new power steering pump within days. The main reason for avoiding motor oil is its viscosity, which does not match the needs of the power steering system.
It is essential to use the correct fluid to avoid these issues. Always consult your vehicle's manual for specific recommendations and avoid using motor oil in the power steering system.
Conclusion
In conclusion, using motor oil in your power steering pump is a risky and potentially expensive mistake. It can lead to a range of issues from reduced performance to complete system failure. If you suspect that motor oil has been added to your power steering system, it is advisable to flush the system and refill it with the correct power steering fluid as soon as possible to avoid long-term damage. Always prioritize the correct fluid for your vehicle to ensure safe and efficient operation.
