    Hello,

    I have a E-60 H and was wondering which fluid is better. I used ATF when I plowed Western and never had any problems. Many people have told me Meyer M1 freezes up and I believe I have had this problem once before. My other issue is that I have to drive 30 miles to get M1. Can I use ATF and if so can I mix the two so that I don't immediately have to drain and flush my entire unit? Thanks for the help.

    Do not use ATF in the Meyer and definitely do not mix ATF and hydraulic fluid, you can use low temp hydraulic fluid from any manufacturer.

    The Meyer fluid is not the cause of the freezing problems you hear about the problem is water getting into the system and for whatever reason it is more prominent in Meyer plows.

    Thanks, good info. I have heard such mixed reviews but have only been running the M1 for the life of my plow.

    If your plow unit is under warranty only use M1 as any other fluid will void your Meyer warranty, if not any snow plow hydraulic oil will work fine.

    I will have to disagree that any hydraulic oil will work fine.

    Changed my oil this season with blue "aircraft grade"
    hydraulic oil. Plow moved extremely slow, especially when
    lifting, and noticed a much higher than normal amp draw.
    Drained out the blue and replaced with M1. Smooth sailing.
    Learned my lesson. Doesn't pay trying to cut corners
    there - imo - and I see some of the Pro's saying the same so...

    I'm a recent convert to "plow oil" from ATF in my E47. I did some research and it's true, at 0 degrees ATF has about 11-12 times the viscosity of plow oil. Below 20 degrees it works much better than ATF and warms up much quicker. At 40 degrees with plow oil the other day my e47 was CRANKING.
