Great oil. Never use any other brand. Thanks AMSOIL

My zero turn had 1000 hrs and one side was significantly less powerful than the other and would not back up on an incline. I had to remove the units to drain the original oil as they were not designed for oil changes. I drained them and added Amsoil and it breathed new life into both sides after only a few minutes of driving. One side is still stronger than the other but both work significantly better and I’m hoping to get several more mowing seasons out of them now. I will be using this in all future zero turns and recommending it to my friends.

Replacement fluid for a John Deere lawn tractor has improved the operation and performance. This transmission runs very hot so hoping it will continue to operate during warmer summer temperatures to come. Fast shipping and good packaging.

Great product! I replaced the fluid in my Simplicity zero turn and this was just the ticket. Amsoil has always been my go to for all my equipment.

Changed my Toro 3000 series hydro fluid & filters at 250 hr maintenance. Time will tell but Amzoil hasn't ever let me down in the past!

I used this oil in my Spartan mower, works great!

When I fixed the transmission leak of my mower with an inboard kit, I decided to use quality transmission fluid. It is cheaper to use good quality transmission fluid than to replace the transmission.

I will see if this stuff is good. The mower drives the same. It already had new fluid in it. Just an early first fluid change in my Hydrogear ZT5400's

It has renewed my mowers positive, firm feeling in the hydraulic system.

I'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.

Switched to Amsoil gear oil for my Exmark Mowers hydrostatic transmission this year. My hydros have always had a slight whine to them. Amsoil gear oil has made the whine go away. They are now the quietest they have ever been.

When using a zero turn mower, we all know that this oil have a tuff job to do! When using this Amsoil product you will not fear having a breakdown in the middle of a summer! Just sit back and let your mechanik and hydrostatic do the work with confident. Thanks to Amsoil.

Had a problem with customers hydraulic mower. Found excessive water/moisture in drive motors on a hunch I thought what about an oil change in non-serviceable drives. Called AMS oil techs and asked if SAE 10-50 could replace SAE 10. Well a mix was added. Still is working fine for a complete season.

I 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.

Did first hydro flush after 500hrs. Smoothed up and quieted pumps. Definitely recommend this product for longevity of your machine.

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.

I just changed the fluid on my Toro Timecutter. At this time it seems to be smoother. I will give an overall review at a later time.

Good clean fluid made my loud transmission noises go away

Transmissions sound a lot quiter and opperate a lot smother, than the oe oil for a new zero turn. Amsoil has my Trust because they make great quailty products. Always been the First in Syntheics.

seems to make mower faster. the price is in line with other synthetics
