Synthetic Blend 4-Stroke (25W-40) Outboard Oil

Synthetic Blend 4-Stroke (25W-40) Outboard Oil

A technology specific 25W-50 marine oil formulated for the world's first and only supercharged and intercooled outboard engine. The unmatched torque and acceleration of this engine requires maximum protection found in this well-balanced combination of today's highest quality synthetic and mineral base stocks. Verado Oil meets the stringent marine operational requirements of all 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. Here are the results from a comparison test between Verado Oil and a popular 15W 50 full synthetic oil. - Verado oil shows significantly better shear stability and volatility, and is higher in viscosity and High Temperature High Shear (HTHS) after shear. - The popular competitive formulation uses a fair amount of VM (viscosity modifier) which is subject to shear, while the Mercury oil contains no VM. As a result, the Mercury oil will hold its viscosity far better in difficult situations. - The HTHS after shear follows along with the viscosity stability, which results in improved bearing protection. - Use of the full synthetic competitive oil resulted in higher oil consumption than the Mercury 25W-5
