  • Potent rust and corrosion inhibitors protect metal surfaces in wet, humid environments, helping prevent damaging rust and corrosion.
  • Excellent cold flow (-60°F [-51°C] pour point) ensures the oil flows quickly at startup for optimum wear protection.

    2 stroke oil

    Many years ago I was given a 9.9 Johnson two-stroke outboard motor because my friend said it smoked too much. I did all my normal tune-ups but it still smoked excessively. I tried new gas and different two stroke oils and additives but it didn't make a difference until I used Amsoil 2-stroke injector oil. After I ran through a couple of tanks of gas, the oil smoking dropped dramatically. Since this experience, I have used this oil in all my two-strokes and I am very happy with it's performance.
    Bottom Line

    Yes, I would recommend this to a friend.
