Here is an interesting article about brake fluid, if you replace it in a regular fashion don't be too caught up with specs.
I was running Gulf R1000 (supposed same as SRF) but my local supplier is out of it so I will be trying out the cheap ATE type 200. I figured it would run cooler with the Essex bbk and if I replace it every season it will never have time to reach its wet boiling point.
