Mercury Premium Two Stroke Oil 3.78L (858022K01)

The Mercury Premium Two Stroke Oil 3.78L is designed for boaters who want reliable, everyday performance from their two-stroke engines. Whether you’re cruising, fishing, or running a work vessel, this oil ensures smooth operation, clean combustion, and long engine life.

Reliable Everyday Protection

Marine engines face tough conditions—heat, load, moisture, and salt. This oil is engineered to handle them all. The Mercury Premium Two Stroke Oil 3.78L reduces wear while protecting moving parts. It works in oil-injected and pre-mix systems, offering excellent versatility for a wide range of outboards.

Clean-Burning Formula for Smoother Performance

This oil keeps your engine clean inside. It helps prevent carbon buildup on pistons, plugs, and ports. That means fewer deposits, smoother idling, and better throttle response. Also, your spark plugs last longer, so you’ll spend less time doing maintenance and more time on the water.

Tough on Corrosion, Gentle on Parts

Saltwater can damage engine internals fast. However, this oil includes anti-rust additives that fight corrosion effectively. It coats vital components and creates a barrier that prevents metal damage, even when the engine is stored. That’s a big win for off-season boaters and frequent users alike.

Large Size for Regular Boaters

The 3.78-litre container is ideal for those who need more oil on hand. It’s great for multiple top-ups or full tank refills. The handle makes it easy to carry and pour without mess, even in tight engine spaces.

For All Standard Two-Stroke Outboards

This oil meets Mercury Marine’s high standards. It’s perfect for carbureted and oil-injected engines but not designed for DFI or OptiMax models. Use it with confidence in your standard two-stroke outboard—whether you’re running a small tiller or a mid-size outboard.

Why Choose Mercury Premium?

You get quality, consistency, and peace of mind. Mercury develops its oils to match the exact needs of Mercury engines. That means every bottle supports maximum performance and engine life—no guesswork involved.
