    By  Tony,  a  Verified Buyer  from  KY.  on  May 05, 2024
    I have a big 60-inch Zero turn mower that had about 170 hours on last hydro oil change, I noticed when mowing the Hydros seemed very noisy, after changing my filters and oil using this fluid they are Quiter than ever. I used the manufactures oil last time which was a semi synthetic oil.
    Bottom Line
    Yes, I would recommend this to a friend.

    Better than oem
    By  BRAD,  a  Verified Buyer  from  Virginia  on  August 28, 2023
    Used this for the initial hydrostatic oil change after the 100 hour break in period on a Bad Boy Maverick. I honestly didn't know it was possible for an oil to make that much difference in a transmission. I could feel the difference in the handle controls, as soon as I started the purge procedure, everything felt tighter and smoother. I mow several pretty steep hills, and after the fluid change, the mower feels like it has more pulling power, and is faster. I would not consider using anything else.
    Bottom Line
    Yes, I would recommend this to a friend.

But I like Amsoil products,very good Quality.

    Hour after hour of use
    By  SCOTT,  a  Verified Buyer  from  Alabama  on  May 02, 2023
    I've been using this oil for my parker hydrostatic pumps on Hustler mowers. Commercial use primarily. Thousands of hours of use. I have had some failures of pumps but both leaked for a couple years before failure. It was not the oil but the pump just giving up after 1000 plus hours. Hour after hour in the blistering heat of summer and they still run. You cannot touch the pumps after several hours of use. All in all I think the only reason they have lasted as long is because I change the filter every year and the fluid of course. Great product.
    Bottom Line
    Yes, I would recommend this to a friend.
