First timeBy ANTHONY, a Verified Buyer on April 17, 2025I'm using this as a top-off for my zero turn mower. I've added just a little more than 6oz.. With probably 4oz. used to fill the expansion reservoir to the cold fill mark. That said, I've mowed for about 2 hours, and yes I have noticed a difference, particularly in the sound, as the oil circulated the usual whine of the hydrostatic pumps quieted some. I'm not attributing this to low oil level, and by adding oil it got better, as stated above, I added it to the expansion reservoir.Bottom LineYes, I would recommend this to a friend.Was this review helpful?

Great hydrostatic fluidBy MG, a Verified Buyer from Pennsylvania on October 24, 2024I use this in Gravely and Toro zero turn pumps and transmissions and it's truly phenomenal. Lever controls are very responsive in fwd and rev compared to Mobil1 15W40 or other equivalent oil specified to be used in hydrostatic equipment. Also the pumps and transmissions have significantly less noise throughout operation. Even in >90°F temperatures.Bottom LineYes, I would recommend this to a friend.Was this review helpful?
