The Benefits of Mercury Marine Engine Oil

Why Mercury oil for Mercury outboards? Mercury’s 25W-40 engine oils are made with advanced corrosion inhibitors that exceed industry standards and outperform all other oil brands. These inhibitors protect against corrosion and rust in wet environments as well as off-season storage. Mercury also uses high-tech additive technology to provide 33% more camshaft protection than other marine oils.

  • Excellent wear and corrosion protection
  • Maintains engine performance and reliability at its peak
  • The thermal breakdown is prevented by extreme temperatures and loads.

Mercury recommends that you change your engine’s oil every 100 hours or once a year.
