Overview

Every boater knows that sinking feeling when it is time to fire up the engine after months of storage.

That’s exactly why Quicksilver Quickstor Fuel Treatment and Stabilizer 8M0047922 earns a permanent spot on my workbench.

Performance & Practical Benefits

Fuel starts breaking down far sooner than most people realize. After a few weeks, ethanol can begin pulling moisture from the air, and that moisture becomes trouble—corrosion, deposits, and tough cold starts. Quickstor steps in before any of that can take hold. Once it is mixed into the tank, it creates a protective environment that slows oxidation, reduces moisture-related damage, and keeps contaminants from forming into sticky varnish.

You will feel the difference when you start the engine after a long layoff. Instead of the rough, uneven idle that sometimes happens after seasonal storage, the engine settles in quickly and runs with a tight, smooth consistency. Throttle response stays clean, and you avoid the hesitation that old fuel often creates. The best part is how little effort it takes—just measure, pour, and you are done. The treatment handles the rest quietly in the background while your boat waits for the next outing.

Why Buy OEM

When it comes to what runs through your fuel system, cutting corners is never worth it. An OEM product like Quickstor is engineered specifically around Mercury Marine engines, which means the formula is balanced, tested, and proven to protect sensitive components. Aftermarket stabilizers often skip on quality or include harsh additives that do more harm than good over time. Quickstor is different—it is reliable, consistent, and tuned to work with the materials and tolerances inside Mercury equipment. If you want long-term peace of mind, OEM is the way to go.
