Power Steering Fluid and the 2016 Lexus IS: What You Need to Know

If you're looking into the 2016 Lexus IS and wondering about power steering fluid, it's important to understand whether this vehicle even uses it and what role the fluid plays if it does. The 2016 Lexus IS, particularly in its standard models, does not use traditional hydraulic power steering with power steering fluid. Instead, it is equipped with an electric power steering system, commonly known as EPS. This means that power steering fluid is not used or required in this vehicle.

Why doesn't the 2016 Lexus IS use power steering fluid? Well, it all comes down to the type of power steering system installed. Hydraulic power steering systems, which have been common in many cars for decades, rely on a pump powered by the engine to circulate fluid under pressure. This hydraulic pressure helps reduce the effort needed to steer the wheels, making it easier to turn the steering wheel, especially at lower speeds.

However, the 2016 Lexus IS comes with an electric power steering system instead. This system uses an electric motor controlled by the car's computer to provide steering assistance. Because there is no hydraulic pump or fluid circuit, there is no need for power steering fluid at all. The absence of fluid also means no fluid maintenance, no leaks to worry about, and generally a simpler, more efficient steering system.

Electric power steering systems offer a few advantages over traditional hydraulic setups:

• They improve fuel efficiency slightly because they don't rely on engine power to run a hydraulic pump.
• They require less maintenance since there is no hydraulic fluid to replace.
• They can be more precisely controlled by the vehicle's onboard computers, allowing for features like variable steering efforts and driver-assist systems.

Now, if you were servicing a vehicle that used traditional hydraulic power steering, understanding power steering fluid and its maintenance would be very important. For those vehicles, power steering fluid acts as the lifeblood of the system, transmitting force and lubricating the steering components. It also helps to cool the power steering pump and prevent rust and corrosion within the system.

Owners of hydraulic power steering vehicles would generally be advised to check the fluid level and condition regularly. Over time, power steering fluid can become contaminated with tiny bits of metal and rubber from the system's internal parts. This contamination can cause the fluid to lose its effectiveness, potentially leading to harder steering or noisy pumps.

For those models that do require power steering fluid, a replacement interval is usually recommended every 50,000 to 75,000 kilometres, but it really depends on the specific vehicle and manufacturer guidelines. During a fluid change, the old fluid is drained and replaced with fresh fluid that meets the vehicle maker's specifications. This keeps the system functioning properly and prolongs the lifespan of the steering components.

Also, if any leaks or damage occur in the hydraulic system, it's critical to address these without delay. Leaking fluid can lead to a loss of steering assist and potentially dangerous driving conditions. When topping fluid up or flushing the system, using the correct type of fluid is essential, as wrong fluids can damage the seals and cause system failure.

Since the 2016 Lexus IS runs on electric power steering, none of that applies. There is no power steering fluid to check, top up or replace as part of routine maintenance. Instead, maintenance for the EPS system focuses more on electrical components and sensors that monitor steering input, and generally these are very durable under normal operating conditions.

So for those considering a 2016 Lexus IS, the lack of power steering fluid might come as a relief. The electric power steering system provides smooth, responsive steering without the hassle of fluid servicing. It also contributes to improved fuel economy and a simpler maintenance routine overall.

In short, if you are servicing or maintaining a 2016 Lexus IS, you don't have to worry about power steering fluid at all. Just keep an eye on other aspects of the car's service schedule and the EPS system will quietly do its job without any fuss or fluid checks.
