Castrol LMA (Low Moisture Absorbing) is all I use in an Spec Miata. First started using it when I worked for an English car restoration shop due to the LMA principle it helped keep brake lines from rusting on cars that where stored. The current bottle says " Castrol DOT4 brake fluid"
IMHO, no need for any of the high dollar brake fluid. Flush regularly.
