Here's why:
* Motor oil and power steering fluid are incompatible. Mixing them will cause severe damage to your power steering system.
* Motor oil is too thick for power steering. It will clog the system's delicate components, leading to:
* Loss of power steering: Your steering will become extremely heavy and difficult to manage.
* Damage to the pump: The power steering pump will struggle to circulate the thick oil, potentially leading to overheating and failure.
* Internal damage: The oil can damage the internal components of the steering system, such as hoses, seals, and the steering rack.
What to do immediately:
1. Stop driving the vehicle. This is crucial to prevent further damage to the power steering system.
2. Contact a qualified mechanic immediately. Explain the situation and request an emergency power steering flush.
3. Do not attempt to flush the system yourself. This is a complex procedure that requires specialized tools and knowledge.
Important Notes:
* The longer you wait, the more damage you risk.
* It's possible that the damage is already done.
* You may need a complete power steering system replacement.
This is a potentially very expensive situation, but it's better to address it right away to avoid further complications.
