LS XR4040 Hydraulic oil

[catton93]

my dealer is telling me to use john deer 303 hydraulic fluid but my owner manuel calls for API GL4 or ISO/VG 46/68. Can anyone tell me if that in the same as 303

Here's the specs on JD 303

Here's a link to another thread on this. 303 is compatible for use in LS tractors but probably costs more.

TSC sells universal fluid and 303 hyd. fluid that will meet the specs for LS. The Universal will work better in colder temps than 303.
