Sir, what hydrualic fluid should I use?
I own a Trex TX650 skip loader. Being a newbie, I called the Terex dealer in northern california (RGW Equipment Sales) and talked to a very nice gentleman to find out what type of hydraulic fluid should I use?
He told me to go ahead and use any 10w motor oil.
He also told me to use 10w oil for the brake fluid also.
Should I laugh or cry?

A lot of machines use lightweight engine oil in their hydraulic systems. Do you have a reason to doubt what they told you?

No, you should thank him.
Power-Trac machines use 10W-40 motor oil for the hydraulics, and my Case skid loader uses the same, with a quart of Case additive. Use whatever the manufacturer said. 10W-40 motor oil is the same anywhere in the country and is readily available.J.J.

Git er done.

I think you should be cautious enough to find and ask another Terex dealer, but the 10W oil does not sound all that far-fetched to me. A good detergent oil will keep your system clean and has good heat characteristics. I would also ask one of those Terex dealers where I might obtain an Operator's Manual so you don't have to guess at issues like this in the future.

About the same price. My tractor called for strait 30W motor oil in the hydraulics. I did not like how slow it was in the winter so I switched over to a 20W hydro oil, AW64 or something like that.

Would 5W motor oil be okay for hydraulics and brakes?

Depending on where you live, whether the 10W - 40 motor oil would work. If that is what the dealer said, then I would use his advise. You can find that oil just about anywhere.
