What Kind of Power Steering Fluid Goes in a Semi Truck?

When it comes to semi trucks, power steering fluid is an essential part of the vehicle. Without it, the steering wheel will become increasingly difficult to turn and could cause serious damage to the steering system.

As such, finding the right kind of power steering fluid for your semi truck is incredibly important. Knowing what kind of power steering fluid goes in a semi truck isn’t always as easy as it might seem, so it’s best to consult with your owner’s manual or a professional mechanic.

The type of power steering fluid you need will depend on several factors, including the make and model of your semi truck. Different models may require different types of fluids, so be sure to double-check before selecting any one type.

You should also consider whether or not you need synthetic or conventional oil-based fluids. Synthetic fluids are more expensive but can offer superior performance and protection in certain conditions.

It’s also important to choose a fluid that is compatible with your vehicle’s seals and hoses. Using incompatible fluids can cause damage to your vehicle’s components over time, leading to costly repairs down the line. This is why it’s always best practice to use manufacturer-recommended fluids whenever possible.

In general, the most common type of power steering fluid used in semi trucks is Dexron III/Mercon ATF (automatic transmission fluid). This type of fluid is designed for use in both transmissions and power steering systems, making it an ideal choice for most semi trucks. It provides excellent lubrication for both components and keeps them functioning properly for longer periods of time.

Conclusion: When choosing a power steering fluid for your semi truck, always check your owner’s manual or consult with a professional mechanic before selecting any one type. Dexron III/Mercon ATF is typically the most common type used in semi trucks and provides excellent lubrication for both transmissions and power steering systems.
