Understanding Power Steering Fluid in the 2020 Holden Commodore

When you're looking into the maintenance and care of a 2020 Holden Commodore, especially regarding steering components, one common question that comes up is whether power steering fluid is involved. For this particular model, the answer might actually surprise some traditional car enthusiasts. The 2020 Holden Commodore does not use conventional hydraulic power steering fluid because it is equipped with an Electric Power Steering system, often abbreviated as EPS.

Unlike older vehicles that rely on hydraulic systems powered by a dedicated pump and fluid reservoir, the 2020 Holden Commodore utilises an electric motor to assist steering. This electric setup means there is no hydraulic fluid to monitor, change, or leak, as you might find in older or more traditional power steering systems.

So why does the 2020 Holden Commodore opt for electric over hydraulic power steering? There are a few reasons that make EPS a popular choice in modern vehicles, especially those designed for comfort and efficiency like the Commodore:

• Efficiency and fuel economy: Hydraulic power steering systems draw power from the engine to run a pump constantly, which can reduce fuel efficiency. EPS systems only use power when steering assistance is actually needed, helping improve overall vehicle economy.
• Lower maintenance: Because there is no fluid or hydraulic components, there's nothing to leak or degrade over time, which generally means fewer maintenance headaches and lower long-term costs.
• Improved steering feel and adaptability: Electric power steering systems can be programmed to change the steering response at different speeds and conditions, offering better handling and comfort for the driver.

Since there is no hydraulic fluid in the electric power steering system of the 2020 Holden Commodore, the common maintenance tasks associated with power steering fluid simply do not apply. That means no topping up fluid levels, no flushing or replacing power steering fluid, and no dealing with potential leaks or fluid contamination.

Instead, maintenance for the steering system revolves mainly around the EPS motor and associated electronic components, which rarely need servicing beyond standard vehicle check-ups. However, it is still important to keep an eye out for any unusual noises, steering feel changes, or warning lights on the dashboard related to steering.

Checking the vehicle for any wear in the mechanical steering linkages or suspension components, such as tie rods, bushings, and ball joints, is essential as part of regular servicing, but these are separate from the power steering system itself and do not involve fluid maintenance.

For drivers who have had experience with older cars that utilise hydraulic power steering, the transition to electric power steering can feel quite different. There is a slightly lighter, more consistent steering effort, and the absence of any dreaded whine from a power steering pump is often welcomed.

As electric power steering relies heavily on electronic sensors and control units, having these components diagnosed and, if needed, updated through authorised service centres can help maintain the EPS system's responsiveness and performance.

So, if you own or are considering the 2020 Holden Commodore, there is no need to worry about monitoring or changing power steering fluid. The move to electric power steering means less fuss, fewer fluids, and a generally more modern driving experience that keeps maintenance simple while offering a smooth, reliable steering feel.
