The Verado four cylinder and six cylinder outboard engines are without a doubt some of the most powerful outboards on the market. In the last year, Mercury formulated a special oil, Mercury 25W and 50W oil, designed to compliment the level of torque and acceleration in a Verado outboard engine. The oil is a combination of synthetic and mineral based stocks of the highest quality, and meets all the demands of the most powerful outboard engines. Mercury engine oil in all its formulations is renowned for superior protection from corrosion, as well as enhanced lubrication to increase the performance of all engine parts.
In addition to Mercury 25W and 50W oil designed for the Verado, there are also 10W and 30W oils which can be used in two cylinder outboard engines.
