Mercury – Quickare Fuel Treatment Additive | Fuel Care System | Liquid Fuel Additive | 8M0047930

Overview

If you’ve spent enough weekends on the water, you learn that most “engine problems” don’t start on the water. They start in the fuel tank, quietly, between trips. A boat that ran perfect last month can suddenly idle rough, hesitate, or feel a little off—and it’s often because today’s gasoline just doesn’t sit nicely, especially when ethanol is involved. That’s why I keep a bottle of Mercury Quickare within arm’s reach.

It’s not a miracle potion, and it doesn’t need to be. It’s simply the kind of Mercury Marine part that helps your engine feel steady and dependable, the way it should. You treat the fuel, you run the boat, and you sleep better knowing you’re not letting varnish, moisture, and corrosion set up shop in your system.

Performance & Practical Benefits

Quickare is the kind of product you appreciate most when you don’t have to think about it. Add the right amount, and your engine tends to start easier, idle smoother, and respond more cleanly when you ease into the throttle. It helps keep the fuel system from getting that sticky, rough feeling that comes from varnish and gum deposits building up over time.

If your boat sits for a couple of weeks—or a couple of months—this matters. Treated fuel is less likely to turn into a problem you “inherit” later. And because it’s built to help manage ethanol-related issues, it’s especially useful in places where ethanol-blended gasoline is the norm. The result isn’t flashy. It’s steady. Reliable. The boat runs like it ran last season, and that’s exactly what most of us want.

Maintenance stays simple, too. Using it consistently can mean fewer fuel-related surprises, less cleanup, and less time chasing down why the engine feels slightly off. It’s a small habit that protects the bigger investment.

Why Buy OEM

There are plenty of additives out there, but OEM products are built with the engine manufacturer’s expectations in mind. This Mercury Marine part is formulated to work across Mercury gasoline engines and fuel systems without guesswork. Long-term, it’s a practical, cost-effective choice—because preventing deposits and corrosion is almost always cheaper than fixing them.

If you’re the type who changes your filters on time and keeps up with service, Quickare fits right into that mindset. It’s simple insurance for the fuel you have to use today.
