    Default What type of fluid for log splitter?

    I recently got an old log splitter. I want to change the hyd. fluid since it has been sitting outside unused for around 10 years. It has red fluid in it now which I assume is transmission fluid. Would it be OK to use tractor hydraulic fluid instead? I have plenty of it and it's a lot cheaper than the atf.


    Thanks,
    Jeff

    I've always used regular auto trannie fluid, in recent years whatever Walmart had cheapest.
    I don't think there is any difference that matters between Dextron, Type-F, or the "formulated for Chryco" stuff in this application.

    I don't see any issue with using tractor hydraulic oil either, especially if you have it around or it is cheap.

    I've been using THF in my splitter for over 10 years and it's worked just fine.
    I can't control my day but I can control my attitude.

    Thanks for the quick replies,

    The hyd. fluid I have is about 1/2 the cost of the atf so I will use that instead. But now I don't have a reason to go to TSC.

    Thanks again,

    I use AW32 hydraulic oil in mine. The reason many use ATF in splitters, tractors, and snow plows is it shows up good in the snow, usually when most are using these items. Makes for quick detection of a leak. I have also seen blue tinted hydro fluid for snow plows that really shows up good in the snow.

    Most likely AW32 / ISO 32 viscosity hydraulic fluid would be the correct one.

    Diamondpilot - You bring up a good point about the color of some of these fluids, it is indeed added to make leak detection easier and sometimes as a visual indicator of what product is being used. If you want a colored oil, any oil you can easily and safely make your own. The dye's used are simply a paraffin based dye. The cheapest way to buy this type of dye is to buy what is called candle makers dye, same stuff only in much smaller quantities. A little goes a LONG way so the eye dropper bottles candle suppliers have are perfect for end users who want to color their lubricants. Here is a supplier I have been using for years. Liquid Dyes

    Actually the reason for ATF in equipment is that it has an additive to keep it from thickening at sub freezing temps.
    Knowing is not enough, you must apply.
    Willing is not enough, you must do.

    Use what you have. I use the universal stuff from Tractor supply in my splitter and old tractors.

    1 or the other , have used both . BUT do NOT mix the 2 . Although it makes a pretty cool effect when it is foaming and bubbling out of the air bleed opening .
