    98 Sportster 1800 - Oil switching

    ok, I have been reading the threads here on the moving from convetional 2 stroke oil to synthetic 2 stoke. My boat has been using Seadoo Mineral Oil 2 stroke since the begining. The engines are 717cc. I want to move over to Amsoil synthetic just like my other 2 jet skis I own just for buying 1 oil type and I like amsoil oil. That stuff works great, very low smoke in the water and I know my skis are protected. My only grip is I wish they would color it since its hard to tell the difference when you premix to regular gas.

    So do I have to drain and clean all the lines oil out to move over to Amsoil or can I just mix it? I am a tall person and I know I could fit in the engine compartment its just not real easy.

    If it was my boat switching to different oil is grounds for pull off lines and cleaning the oil system. I would flush the lines and check for metal.
    I've had customers use what ever back in the days. Like 10w30 and those 717 still ran.. WTF!
