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

A technology-specific 25W-40 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 4- and 6-cylinder Verado 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-40.
