Hi all
The Ford dot 3 brake fluid is the same as the old part # c6az 19542 ab. It is ford spec# esa-m6c25-a. Same dry boiling point 550 & wet 284. The tall blue can you purchased is dot 4 part# ys4z 19542 aa. It is recommended for use in the Focus & other applications that dot 4 is specified.

MSRP for the dot 3 is $3.54 it is the dot 4 that is $10.31. I and RST have used the dot 3 for many years with no problem. We carry a supply with us if anyone needs any we can help you out.
