It is a blend of synthetic and mineral base oils, combined with advanced additives to provide superior protection against wear, corrosion, and deposits. This oil is suitable for use in both freshwater and saltwater environments, making it a versatile choice for all types of boats.

Benefits of using Mercury 25W-40 Synthetic Blend

  • Superior protection: The advanced formula of this oil provides excellent protection against wear, ensuring that your engine runs smoothly and efficiently.
  • Enhanced performance: The synthetic blend formula helps to reduce friction and improve engine performance, resulting in better acceleration and fuel efficiency.

  • Versatile use: Whether you have an inboard or outboard engine or operate in freshwater or saltwater conditions, this oil is suitable for all types of boats.

How to choose the right viscosity

Mercury 25W-40 Synthetic Blend is available in two different viscosity options – 25W-40 and 10W-30. The first number (i.e., 25 or 10) indicates the oil’s thickness at cold temperatures, while the second number (i.e., 40 or 30) represents its thickness at high temperatures. When choosing the right viscosity for your boat’s engine, consider factors such as operating temperature, climate, and manufacturer recommendations. For most boating applications, the 25W-40 viscosity is suitable. However, if you operate your boat in extremely cold conditions, the 10W-30 option may be a better choice.

This oil can be used in both four-stroke outboard and inboard engines. For best results, follow these steps when changing your boat’s motor oil:

  1. Run your engine for a few minutes to warm up the oil.
  2. Turn off the engine and remove the dipstick.
  3. Place an oil drain pan under the drain plug and remove it using a wrench.
  4. Once all the old oil has drained out, replace the drain plug.
  5. Using a funnel, pour in new Mercury 25W-40 Synthetic Blend into the oil fill hole until it reaches the recommended level on the dipstick.
  6. Replace the dipstick and start your engine to circulate the new oil throughout your engine.
