Mercury – SAE 0W-30 Full Synthetic Power Steering Fluid | Verado & JPO Systems | 858076K01

Overview

There’s a distinct confidence that comes when your steering responds exactly as it should — quick, quiet, and smooth, no matter the water conditions. That feeling doesn’t just happen; it’s built on the small details that keep your boat running right. Mercury SAE 0W-30 Full Synthetic Power Steering Fluid is one of those details. Designed for the advanced steering systems that drive Mercury Verado outboards and Joystick Piloting setups, this fluid ensures your control stays effortless, responsive, and reliable — from idle speeds to full-throttle turns.

Key Features

Performance & Practical Benefits

When you’re piloting a boat that answers every touch of the wheel, it’s easy to forget what makes that precision possible — until it’s gone. This Mercury Marine part keeps that control steady, even after hours of use in demanding conditions. The synthetic formula resists thermal breakdown and oxidation, which means consistent hydraulic pressure whether you’re in the heat of summer or running cold water at sunrise.

It delivers a smooth, connected feel through the wheel — no noise, no lag, just clean responsiveness. The fluid’s low viscosity ensures fast actuation, while corrosion inhibitors shield the system’s delicate internals from moisture and salt exposure. The result is steering that feels tighter, lighter, and more controlled — the way Mercury designed it to be.

You’ll also appreciate the peace of mind that comes from knowing every component in your steering system is protected, clean, and ready to perform the next time you take the helm.

Why Buy OEM

You wouldn’t trust your Verado or Zeus system to just any hydraulic fluid — and you shouldn’t have to. This genuine Mercury OEM power steering fluid was developed by the same engineers who designed those systems. That means it’s tested under real-world marine conditions — salt spray, full-day heat, vibration, and load — to guarantee the performance your boat was built for.

Aftermarket fluids might claim compatibility, but they rarely deliver the same stability, corrosion resistance, or low-temperature performance. With Mercury OEM fluid, you’re getting the exact formula your system needs to operate flawlessly. It’s one of those smart choices that keeps your setup tight, quiet, and reliable for the long haul.
