Hi all,

My shop recently purchased an Okuma GCU 300/400 Cylindrical Grinder. This machine was probably made some time in the 70's and so the operator's manual calls out a lot of lubricants that have been discontinued. I have managed to find equivalent lubricants for most of the machine but I am hitting a wall when it comes to finding an equivalent for Turbine Oil No. 140. Can anyone point me in the right direction as far as finding an equivalent oil. Thanks!
