    Royal Purple oil

    What do you guys think about Royal Purple Max Cycle 10w40 motor oil in a 08 stx15f? I am using amsoil 10w40 marine now, just wonder if its worth the considerable extra cost.

    Why are you thinking about changing brands and second, why would you use a motorcycle oil in a PWC?

    Here is the Motorcycle oil test. Decide for your self what brand you would like to use. I my self would stick to a Marine Synthetic Oil.

    my ski blew the oil cooler o ring and flooded the engine with salt water. I believe it ran like this for quite a while till the oil gunked up so much it showed low on the dipstick. My point is I believe the amsoil marine saved the engine, as the engine is still fine. I cant believe it even ran with that much water in there. That amsoil must have some serious anti wear capabilities.

    Your rings will be fine and they will seat with the AMSOIL. Do a leak down test and you will know how your rings are doing.
