Advice on Swap to Dot 5 - New MC

And if you really want to get nuts:
When you research "When brake fluid is tested according to S6.10.3(a)When brake fluid is tested according to S6.10.3(a)"...

S6.10.3 reads:
Brake fluid is mixed with an equal volume of SAE RM-66-04 Compatibility Fluid, then tested in the same way as for water tolerance (S6.9) except that the bubble flow time is not measured. This test is an indication of the compatibility of the test fluid with other motor vehicle brake fluids at both high and low temperatures.

Compatibility Fluid?? Whassat?
