Yes, they are different.
Brake fluid will eat the jack seals. Some people might suggest Transmission Fluid or motor oil, but there's really no need -- hydraulic jack oil is inexpensive and easily available at many tool, hardware, and auto parts stores. And it's supposed to keep seals in the best possible condition. Here are a few part numbers you can search for:
GUNK 4KTN1 Hydraulic Jack Oil, 12 Oz
Gold Eagle Heavy Duty Jack Oil - JF16
"Ace" Hydraulic Jack Oil (at Ace Hardware Stores).
As of this writing in mid 2010, a 12 oz bottle is about $4.

No. Only hydraulic oil can be used in hydraulic jacks. Hydraulic oil is compressed (a requirement for use in hydraulic cylinders) so that there are no air or other gases dissolved in it. Before adding hydraulic fluid to the jack, be certain that the fluid has been sitting for at least 24 hours to avoid introducing air into the hydraulic fluid in the chamber.You should be able to purchase hydraulic oil (sometimes it will be labeled "Hydraulic Jack Oil/Fluid or Jack Oil/Fluid) in small or large quantities, inexpensively, at any auto parts store worthy of the name. It can also be purchased at some Walmarts and any heavy equipment supply stores.
