Can I use Lucas Synthetic DOT 3 Brake Fluid instead of the Subaru brand DOT 3 on a 2015 Subaru Crosstrek with 92K miles?

Looking into this a little further...

The manual says "Never use different brands of brake fluid together."

Is this just Subaru wanting me to buy their fluids only verbiage?

No, it says do a full flush of the older fluid and replace it with the new one. No mixing.
