*Reserve
alkalinity (RA) is a team used to indicate the amount of alkaline inhibitors
present in an antifreeze formulation. It is incorrect to relate a high RA with
a high-quality antifreeze formulation contain many new inhibitors which give
added protection to certain metals but do not raise the RA number.
