I have four JD's, 1960 - 1970, and all call for a different hydraulic oil. My 1010 crawler calls for 10w or 5w-20 and my 2510 & 4020 tractors call for JD special type 303. While my 544 uses both 303 and type C-2, but the manual says not to use 303 in place of the C-2. My question, does anyone know if Hygard, which is what I have been using, will cause any difference in preformance for any of these applications? My Deere dealer says the Hygard is a replacement for all of the above, but I believe I must be sacrificing something with a one oil replacement.
Thanks

Hydraulic Oil ???
Lavoy, Deere makes a low viscosity hygard, would that work better than regular hygard in the crawler? Or, does Deere make a "straight hydraulic oil"?
The C-2 is an oil designation of the Allison transmission, hydraulic steering and brakes on the JD544, the loader cylinders have a seperate resevior and pump for the 303/now hygard.

The low vis Hygard will make it squeal worse, it is enough thinner. It won't hurt anything, but you will lose some more pressure.
Deere does not make a straight hyd oil anymore that I know of. It is not hard to find though, any Farm and Fleet or TSC type store will have it on the shelf. I think the Advance Auto parts store in town even has it.
Talk to your local dealer, they may tell you that the low vis is a substitute for the C2.
