Hydraulic Fluid Choices

[mndave]

The Shell Rotella HD is awful in colder temps and was basically unusable in MN winters. I swtiched to full synthetic Lucas "Universal Hydraulic Fluid" and it has been outstanding so far.

Here's the Lucas fluid at a great price: Lucas Oil 10100 Lucas Universal Hydraulic Fluid | Summit Racing

Here's my thread that has some other synthetic options too: Low temperature hydraulic fluid?

I'm in the same boat as the original poster, I'm going to be doing my first service soon. My issue is I live in Central Texas where the summer gets Hot and the winters maybe down in the teens. I'm looking for a good Full Synthetic fluid that'll hold up to the High summer temperatures.

Chevron makes a full synthetic, of course Amsoil and Lucas has been mentioned, I'm running a para-synthetic Cen-Pe-Co multi purpose fluid which has worked out well for me.
