Exxon Hydraul 560 has on the bucket that it meets "JI Case 1204-07/09" specs but it cost me about $40/bkt.
If that bucket is bigger than 4 gallons, you're getting a good price. Even at TSC, the off brand MS-1209 oil by the bucket works out to $10 per gallon, same as dealer cost around here. I figure I might as well support my dealer and get it there.
300 hours on the DX29, 850 on the JD 240 and too many to count on the Cadet
