Hydraulic fluid for 750J

[StanLee]

The hydraulic tank decided to call it quits and spill the fluid everywhere, so now I have a problem. I took care of the tank and that part is all good, but now I'm struggling to decide which fluid to use. Stick with JD one, or go aftermarket?

For me, you should definitely stick with the JD hydraulic fluid if you want to keep things simple and safe. Aftermarket could be good but they're a little complicated than just going spec. Plus, some people only buy aftermarket for affordability. Since you got the JD as an option there, I don't think you have budget restraints LOL.

definitely check your operator's manual if you still have it. it'll list the exact specs for the JD fluid (like JDM J20C or J20D).
if you go aftermarket, make sure it meets or exceeds those exact specs. Sometimes, cheaper 'universal' fluids don't quite cut it, especially if your system has wet brakes or clutches that need specific friction modifiers. Peace of mind with OEM is real, but a good aftermarket that matches specs is fine

Is there a noticeable difference in performance between J20C and J20D in warmer climates? I'm in Nevada, so I'm guessing J20C might be the better fit?

I'd stick with JD fluid if you can, it's formulated specifically for their systems and helps avoid compatibility issues but, a high-quality aftermarket hydraulic oil that meets the same specs can work fine anyway
