The Mobil DTE 10 46 hydraulic oil is the best.
Works great at temps. 30 below in my Ford 1520 deisel tractor.
My front bucket and backhoe work in these temps with ease thanks to this oil.
I highly recommend PSC and there products.They were also very helpful in Choosing the right oil for what I needed it for.
Thank you very much, will do business again.
