    My Bob Cat Fast Cat Pro 22hp 52" has
    Hydrogear 3100 transmissions.
    Manual calls for 20w 50 API SL motor oil ,can I use Mobile 1 Motor Cycle oil 20w50 API SH?

    I would suggest Mobil 1 15W50 - I think you should look for an API SL equivalent oil.
    When I asked Hustler on one of their models with a hydro-gear integrated unit (which specs 20W-50,) they said use Mobil 1 15W-50.
    If you are open to other brands of oil, I would highly recommend Amsoil's 20W-50 synthetic motor oil. http://www.amsoil.com/storefront/aro.aspx

    RickyDL is that the Mobil 1 vTwin 20w50?
    That's the only 20w50 Mobil 1 I see in their line

    LC based on what I know about oil I think the 15w50 should be good, just worried the Hydrogear specs 20w50
    Amsoil is my second choice, just want something I can get off the shelf locally
