Can You Put Motor Oil in Power Steering?

No, you cannot put motor oil in power steering. Power steering is a hydraulic system that uses fluid to assist in turning the wheels. Motor oil is too thick and will not flow properly through the system.

This can cause damage to the pump and other components.

  • Check the power steering fluid level and add fluid as needed
  • Remove the power steering pump cap and clean any debris from the reservoir
  • Pour new motor oil into the power steering reservoir until it reaches the full line
  • Replace the power steering pump cap and start the engine to check for leaks

Can I Use Cooking Oil for Power Steering Fluid?

If your power steering fluid is running low and you’re in a pinch, you may be wondering if cooking oil can be used as a substitute. The answer is yes, but it’s not ideal. Cooking oil is thicker than power steering fluid and can clog up your system, so it’s best to use it only as a temporary fix.

If you do need to use cooking oil for your power steering fluid, make sure to add just a small amount. You don’t want to overfill the reservoir and cause more problems. Once you’ve added the cooking oil, start the engine and turn the wheel from lock to lock a few times to help work the oil into the system.

Keep in mind that using cooking oil as power steering fluid is only a stopgap measure. As soon as possible, head to an auto parts store or dealership to get the proper power steering fluid for your car.

Can Engine Oil Be Used for Power Steering?

Most people believe that since both engine oil and power steering fluid are hydraulic fluids, they can be used interchangeably. However, this is not the case. While both fluids are similar, they are not the same, and using engine oil in your power steering system can cause serious damage.

Power steering fluid is specifically designed for use in power steering systems. It is a high quality hydraulic fluid that contains special additives to protect against wear and corrosion. Engine oil does not contain these additives and will break down quickly when used in a power steering system, leading to expensive repairs.

What Else Can I Use Instead of Power Steering Fluid?

If your car is leaking power steering fluid, you may be wondering if there’s anything you can use as a temporary fix. The short answer is no. Power steering fluid is specially formulated to lubricate and protect the components in your power steering system, and using anything else could damage your car.

That said,
if you’re in a bind and absolutely need to drive your car, you can try topping up the power steering fluid with automatic transmission fluid. This isn’t ideal, but it may buy you some time until you can get to a mechanic. Just be sure to have the system flushed and refilled with proper power steering fluid as soon as possible.

Is Power Steering Fluid the Same As Motor Oil?

No, power steering fluid is not the same as motor oil. Power steering fluid is a hydraulic fluid that helps transfer power from the steering wheel to the wheels, while motor oil lubricates and protects engine parts.


Yes, you can put motor oil in your power steering fluid reservoir.

However, it’s not recommended and here’s why. Motor oil is designed to lubricate engine components, whereas power steering fluid is designed to lubricate the power steering system.

Power steering fluid has a different viscosity and chemical composition than motor oil, so using motor oil in your power steering system could damage the pump or other components.
