Mercury – Quicksilver Synthetic Motorcycle Oil | V-Twin 4-Stroke Series | Synthetic Blend | 8M0175745

Overview

There’s something unmistakable about the way a V-Twin comes to life — that low, rolling rumble that settles in your chest before you even twist the throttle.

That’s where Quicksilver’s 20W-50 Synthetic Motorcycle Oil earns your trust.

Performance & Practical Benefits

If you ride a V-Twin, you already know how important oil is. A good blend keeps things cool. A great one keeps everything feeling tight, steady, and unmistakably smooth. This formula does exactly that. It holds its viscosity even when the engine is working hard in high temperatures, which means your motor stays protected during long uphill pulls or those slow, hot crawls through town.

The synthetic blend also forms a strong barrier against wear. That’s something you’ll notice over time — less ticking, cleaner internals, and a more confident response when you roll on the throttle. It helps prevent corrosion during storage too, which is a real benefit if your bike sits through winter or waits out long stretches between rides.

And because it’s designed with air-cooled engines in mind, you get reliable protection where it matters most. The oil resists thermal breakdown, reducing the chance of deposits or sludge that can choke performance and shorten engine life.

Why Buy OEM

Choosing OEM-quality oil isn’t about brand loyalty — it’s about knowing what works. Quicksilver’s synthetic blend is engineered and tested specifically to handle the stress and temperature spikes that V-Twin engines generate. It’s built to last, built to protect, and built to keep your motorcycle running exactly the way it should.

Cheaper oils may look appealing until they thin out under heat, create clutch issues, or leave deposits behind. Using an OEM-level product is simply the practical decision for long-term engine reliability and smooth performance.
