Understanding Power Steering Fluid in the 2018 Subaru Outback

The 2018 Subaru Outback is an excellent choice for those who enjoy reliability and versatility in a vehicle. However, when it comes to power steering fluid, this model doesn't rely on the traditional power steering fluid system. Instead, the 2018 Subaru Outback is equipped with an electric power steering (EPS) system, making the conventional hydraulic power steering fluid irrelevant to this car.

One might wonder why Subaru and many other automakers have opted to eliminate power steering fluid in favour of EPS. The shift to electric power steering systems is primarily due to efficiency. The hydraulic systems of yesteryear required a consistent engine power draw to operate the pump and maintain fluid pressure. This continuous power drain translates to higher fuel consumption and more frequent maintenance requirements. By moving to an electric power steering system, the steering effort is managed by an electric motor instead, which only engages when needed, leading to improved fuel economy and fewer maintenance headaches.

As an owner of a 2018 Subaru Outback, you might expect the maintenance routine to place a heavy emphasis on the power steering fluid. However, with an EPS system, you can wave goodbye to concerns about checking fluid levels or leaks. The EPS units are designed to be largely maintenance-free, with fewer moving parts and without the need for periodic fluid replacements. Simplifying the mechanical components reduces the chances of system failure and maintenance needs.

EPS offers other advantages too. It provides variable steering assistance based on vehicle speed, less assistance at higher speeds makes steering more stable, whereas more assistance at lower speeds, such as while parking, helps enhance manoeuvrability. The nature of EPS allows engineers to program steering feel and responsiveness, often improving the driving experience, which is why many car manufacturers are adopting this technology.

For those accustomed to traditional maintenance schedules that include items like changing out the power steering fluid, it's refreshing to know that with the 2018 Subaru Outback, that's one less thing to worry about. Instead, keep an eye on the electrical components associated with the EPS system. Although there's no fluid to replace, ensuring the electrical connections, steering motor, and system sensors are functioning optimally is vital for steering precision and safety.

While the move to EPS undoubtedly simplifies stewardship of your vehicle, it doesn't absolve one from all steering-related checks. Drivers should remain observant for any unusual noise or rough steering response, which could indicate an issue within the EPS unit. In such instances, consulting with a qualified mechanic or visiting an authorised service centre will ensure things remain in good order.

It's important to remember that though the absence of traditional fluid changes makes for an easier maintenance schedule, there is still the potential for electrical faults within the EPS system, just as hydraulic systems had their quirks. Therefore, routine check-ups during your regular car service remain a cornerstone of ensuring that all components are functioning harmoniously in your Subaru.

• Subaru has embraced EPS systems to create more environmentally friendly vehicles, as these systems add to fuel economy by reducing engine load.
• The EPS systems found in cars like the 2018 Outback tend to be quieter, offering a smoother and more pleasant driving experience.

Owning a 2018 Subaru Outback means experiencing the joys of driving with the reassurance of a vehicle designed for peak efficiency and a streamlined maintenance routine. If you're ever unsure about specific components or feel irregularities in your steering, it's always best practice to rely on expert advice to keep your ride smooth and responsive.
