Hydro Gear 2800

[goingwest]

My Hustler mower has twin Hydro Gear 2800 drive units that call for 20W50 motor oil.I have 2 gal of Motul 7100 20W50 but it says it is an ESTER Synthetic. I have no idle what this Ester stuff means so help me out. Can this be used in the Hydro Gear units.
The Motorcycle is gone so I need to use the oil it something.

Typically, an engine oil with a minimum rating
of 9.0 cSt (55 SUS) at 230° F (110° C) and an
API classification of SL is recommended. A
20W50 engine oil has been selected for use
by the factory and is recommended for normal
operating procedures.


Apparently you can use any API rated SL oil whether mineral, synthetic blend, or full synthetic as there are no restrictions against using a synthetic oil.

Thanks for the replies guys. I was not sure about the Motul 7100 because of it being an Ester base oil as I know nothing about about Ester Oil other than a lot of Motorcycles use it.
