    If my memory serves me right it is 10W-30 or straight SAE 30

    I cannot find it on MEC's web site.

    Maple syrup and that will raise the point of impact 20 per-cent.

    Hope this helps

    I have a very old Hustler. I talked to MEC about this long time ago & they said use 20 WT NON-detergent motor oil. This would help avoid foaming. They were very specific anout not using a hydraulic fluid. Suggest you call,this advise may not cover later pumps.

    When all else fails read the directions.

    The factory decal on my pump says "10W30" and gives a level to fill also.
    Also most hydraulic fluid applications use an oil closer to 10W than 30W.

    I finally got a reply from MEC they reccomend 10W-30, I thought that was what they recommended.

    Overbored Thanks, butnI wanted to keep the pump assy on the floor, You might try that Maple Syrup in your gas tank for better mileage and temporary more horsepower until the engine locks up, it would run sweet for a while just like your recommendations.

    It is not necessary to use a multi viscosity oil when it comes to the hydraulic pump. Come on, is not like you are taking the pump around the race track. You use the pump in a controlled enviroment therefore the use of a multi-viscosity is not needed.

    Yes; oil foams, and worse in certain applications. Some hydraulic applications and many compressor applications cause air to be entrained in the fluid.

    As for multi-vis, smooth operation at startup- before the oil thins due to heat accumulation- is a likely reason for the recommendation. Multi vis will offer a more uniform viscosity across this application's operating temperature range.

    I bought a Hydro Mec well used from a friend a long time ago and it was filled with Auto Transmission Fluid way back then and still running on the same. Doesn't miss a beat! May not be the company's recommendation, but works just fine.
