Mercury – Quickare Fuel Treatment Additive | Fuel Care System | Liquid Formula | 8M0058690

Overview

Every boater knows the uneasy feeling of turning the key after your boat has been sitting for a few weeks. You hope the engine wakes up cleanly, without stumbling or coughing through stale fuel. That peace of mind — the kind that makes you relax the moment the motor fires — comes from taking care of your fuel system long before you hit the water. Mercury Quickare Fuel Treatment Additive gives you that confidence. It keeps fuel fresh, prevents the problems you don’t see, and helps the engine stay sharp and responsive every time you head out.

Key Features

Performance & Practical Benefits

Quickare works quietly in the background, but you feel its impact every time you run the engine. Fuel stays fresh instead of turning cloudy or stale. Starting becomes easier — especially after the boat has been resting in the driveway or at the dock for a spell. When varnish and gum are cleared from the fuel system, you’ll notice steadier idling, cleaner throttle transitions, and fewer annoying hiccups when you pull away from the ramp.

The protective additives make a difference too. Ethanol-blended fuels can draw in moisture, and moisture leads to corrosion and phase separation. Quickare helps fight that, keeping metal surfaces cleaner and reducing the chance of clogged injectors or sticky carburetor parts. The engine simply feels smoother and more predictable. Even at low speed, everything stays calm, steady, and controlled.

For many boaters, it’s the cumulative benefit that matters most. Using Quickare at every fill-up helps keep the fuel system clean season after season, which means fewer surprises when you’re far from shore and relying on the engine to carry you home.

Why Buy OEM

Mercury Marine parts are tested in real conditions — rough seas, long hours, and unpredictable fuel quality. With Quickare, you’re getting a formula designed specifically for gasoline engines that face heavy loads, varying speeds, and long periods of storage. Aftermarket additives may look similar, but they rarely have the same level of engineering behind them. When you choose OEM, you’re choosing consistency, protection, and a product made to work right the first time. It’s the kind of practical decision seasoned boaters swear by.
