    Is it better to change the motor oil in your ZTR in the Spring or the Fall just before you store it. Or, does it matter?

    That's a strange question from someone who joined this forum in Nov of 2004!!! Are we missing the good ole "Owner's Manual"?

    You say ZTR ............. what difference does it make? If its got an engine, then you change the oil ........ at regular intervals, when you're ready to store it away for the winter, when you're ready to start using it in the spring, etc., ....... not exactly rocket science!

    I'm going to assume a few things about your question, but then you'll probably probably prefer my answer to others you may read...

    I assume low use and hours of operation only justify an annual change. In that scenario the best answer would be a fall change. This eliminates the acids in the oil and leaves the least amount of moisture in the oil as well.

    btw, this fall oil change should always be with at least partial petroluem oil (vs synthetic), and the engine should run for a few minutes w/the new oil before final shutdown..

    Finally, even with really really low use, an at least annual (fall) oil change is suggested.

    Once a year or every 100 hours works. In the fall will be fine, some of you fellas have interesting views of condensation in the oil...strange IMO. Not saying it wont happen but it isnt likely that fresh oil is going to attract water?

    Fresh oil does not attract water but not getting a motor, exhaust to proper temp does not burn the condensation already there. Why contaminate the oil needlessly.

    Every 40 hours of use, change the oil. Change the filter every other oil change. Or, as my dad always says:
    "When all else fails, follow the instruction manual."

    Why not store the engine with no oil in it until spring when you go to use it? Just be sure to write yourself a large sign saying no oil in motor ....

    What would that accomplish? You can do it. When we store bikes we also you fogger in the heads to lubricate them and also we'll crank the motor W/O starting to run oil on the cylinder walls, etc...

    If the question is when to change the oil during seasonal operation,Every 45-50 hours, or in the case of our Z-Turns ounce a week.

    If you are taking storage, change after the season is over, in addition, pour a bit of oil down the spark plug hole's, pull the the starter cord to turn the piston and distribute the oil in the cylinder, helps prevent possible rust.
