    gummed up oil tank and filter on 2002 RXDI 951

    I'm just wondering..if anyone has seen where someone mixed two different types of oils to make a solid grease that would clog up an oil filter?

    I cut my oil filter in half and it looked like a hard greasy paste?

    Anyone ever done this to their ski? I bought the machine like this..but ended up rebuilding it twice (second time with a very well cleaned oil tank + lines + new filter)

    I bought a blown 2000 GTX di and found the cause of engine failure to be that 4 stroke drain oil used in the ski. I have not yet seen a "jelled" condition w/ mixing 2 stroke oils.

    this is sometimes caused do to water in oil. it becomes like a toothpaste.
    if you try this yourself you will see what i mean, its like a waxy paste.

    I think running premix is the safest way to go. thats my personale opinion,

    You can not pre-mix a DI.

    The fuel is injected (Directly) into the combustion chamber. Any oil in the fuel would just be burned and sent on its way....without ever touching the crank.

    The air pump is also lubed by the oil pump.

    that makes complete sense. never thought about that. One more thing, would this engine be something similar to and e-tec?, man I wish they try something like that on a seadoo. I see those engines on snowmobiles.

    In reading a little on the E-Tec it seems that it is also direct injection but that is about the only similarity.

    Other than the DI fuel injection system the DI is more or less a 951 (as far as construction and materials). An E-Tec seems to have some pretty fancy stuff in its makeup. That is good or bad, depending on how much cash you have available.

    Most all high performance 2 stroke oils will eventually deteriorate when exposed to air (Oxygen) after several years. They turn into a 'gell". There are anti-oxidants in the oils, but, after awhile they break down too. Always, always always check your oil if it is more than 18ish months old. That "gell will plug your oil pump and you know the rest.

    I have seen oil do exactly what you describe when 2 oils were mixed it used to be quite common . I have seen diesel put in the gas tank on a DI. DI means Diesel Injected dont it ?
    A friend of mine had a Di that kept seizing it was causes by water in the oil tank and it clogged the filter. Good reason to completely go through a boat when building an engine in a Ski new to you.
