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

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.

This oil makes hydros run amazing.

Shipment arrived quickly.But part of the box inside and out,and the Order Paperwork,and some of the containers were Saturated with oil.There were 3 -1 gallon jugs in the box,looks like an employee used an old box that was contaminated with Oil.None of the jugs had a leak,this box should not have been used.!! But I like Amsoil products,very good Quality.

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.

Work's amazing pumps more responsive quieter run cooler also good price compared to competitors

Great oil for the hydraulic system of my zero turn mower ! Purchase with confidence.

Had trouble with steering my zero turn mower for years. The dealership couldn't fix it. Had 130hours of use. Servicing the transmissions was called for at 400 hours. I decided to service the transmissions anyway and use Amsoil's product and new filters. Problem solved. I rarely leave reviews so this means I am honestly impressed.

Seems like a great product. Once I change the oil and filters I hope all will be well. Great product for a specific use.

I have a lawn care business I use this oil in my 0 tern transmissions runs smoothly now and not as hot

Use in my zero turn lawn mower and seems to last alot longer and smooth running compared to Mobil one .

Just rebuilt my mowers zero turn transmissions. Wanted the best transmission fluid for them and I think this is it. Thanks for making this product.
