What Type of Hydraulic Fluid Goes in a Tow Truck?

Tow trucks rely on a hydraulic system to power the lift used for towing and recovery. This hydraulic system requires a certain type of fluid in order to work properly.

Without the right type of fluid, the system will not be able to lift or hold any weight, which could lead to major problems and even dangerous situations. So, what type of hydraulic fluid goes in a tow truck?

The answer is not as simple as it may seem; it depends on several factors such as the manufacturer’s recommendations and the type of hydraulic system used in the vehicle. Generally speaking, most tow trucks use mineral oil-based hydraulic fluids. These fluids are typically composed of petroleum-based oil combined with additives such as anti-wear agents and detergents.

In addition, some tow trucks may also use synthetic oils or semi-synthetic oils in their hydraulic systems. Synthetic oils are typically derived from esters or other synthetic compounds and are generally more expensive than mineral oil-based fluids. Semi-synthetic oils are a combination of both mineral oil and synthetic oil.

It is important to note that each manufacturer may have their own specific recommendations for the type of fluid that should be used in their vehicles’ hydraulic systems. As such, it is important to consult with the manufacturer before purchasing any type of fluid for your tow truck.

Conclusion:

Overall, it is important to know what type of hydraulic fluid goes into a tow truck before purchasing any fluids. Generally speaking, most tow trucks use mineral oil-based hydraulic fluids; however, some models may require synthetic or semi-synthetic oils instead.

To ensure you purchase the correct fluid for your vehicle, always consult with the manufacturer prior to making your purchase.
