Please help hydraulic question

[Pooie69]

I bought the rc4wd system for my dump truck, what hydraulic fluid can I use, they want $30 for 16oz that's insane.

10W hydraulic oil.

I currently like CAT hyd oil with antifoaming agent.

Was using Plow oil - Freddy believed highly in this.

I just use what I run in my mini excavator. It's ISO 46 and works fine with my Jung and home made pumps. Probably a bit thick though I guess but it's $60 for 5 gallons.

F+L petroleum products USA, I bought the SHELL TELLUS S2 V22, bought mine in 5 gallon, but I have other RC4wd equipment also, and change my oil a alot.
