Power Steering Fluid for the 2018 Lexus IS: What You Need to Know

When it comes to the 2018 Lexus IS and its power steering system, there's an important detail that often confuses vehicle owners. Unlike many traditional vehicles that rely on hydraulic power steering fluid, the 2018 Lexus IS takes a different approach. This model is equipped with an Electric Power Steering (EPS) system, which means it does not use or require power steering fluid at all.

So why does the 2018 Lexus IS skip the power steering fluid? The answer lies in the evolution of automotive steering systems over the past decade. Many modern cars, including the Lexus IS from 2018, have made the switch to electric power steering. Instead of a pump driven by the engine circulating hydraulic fluid to assist steering effort, the EPS system uses an electric motor to provide the necessary power assist. This set-up offers several advantages such as improved fuel efficiency, reduced maintenance, and enhanced steering precision.

Without the need for hydraulic lines, pumps, or fluid reservoirs, the electric system is more compact and typically more reliable over time. Since it does not depend on fluid pressure, there's no risk of leaks or the gradual degradation of fluid quality affecting steering performance. This is why traditional power steering fluid changes are not part of the 2018 Lexus IS's regular maintenance schedule.

That said, even though there is no power steering fluid, the EPS system still requires periodic checks. The electric components, sensors, and motor should be inspected to ensure the steering feels tight and responsive. If any warning lights related to steering or EPS appear on the dashboard, it's a good idea to have the vehicle scanned by a professional technician to diagnose the issue.

For those used to older vehicles, the absence of power steering fluid might feel strange. However, the benefits of EPS are significant. Besides eliminating fluid changes and associated mess or leaks, it also allows for advanced features like variable steering assist depending on speed and driving conditions. This adds an extra layer of safety and comfort for everyday driving.

Overall, the 2018 Lexus IS's power steering system showcases how modern automotive technology has evolved. While you won't be topping up or flushing power steering fluid, it is still important to maintain the EPS system through regular inspections and attention to any handling quirks. Keeping your Lexus's steering system in good shape will help ensure smooth, reliable control for years to come.
