Mercury 25W-40 Synthetic Blend Outboard Oil meets the stringent marine operational requirements of all of Mercury’s new 4- and 6-cylinder models. First in class for all FC-W durability test properties with industry-leading internal marine engine corrosion protection. Why is using 25W-40 Mercury 4-stroke outboard oil so important? The marine environment is one of the most demanding environments in which an engine can operate. Outboard engines are often used for extended periods at wide-open throttle, harsh saltwater, and intense UV sunlight. Then, Mercury outboards often sit in storage over the off-season, in many cases, without any use. Focusing on these demands, 10w-30 Mercury 4-stroke is engineered for the unique needs of marine engines and rigorously tested to meet high standards, protect your Mercury outboard, and provide many years of engine life.\u003c\/p\u003e\n\u003cp\u003eMercury 25W-40 oil was formulated for the world’s first and only supercharged and intercooled outboard engine.
