What brake fluid to use?
Es300 1997
what brake fluid is best for my car?
Im thinking of either Valvoline Brake Fluid: Dot 3 & 4; Synpower(R); 32 oz. or Prestone Brake Fluid: Dot 3; High Temp; 32 oz. from the locol auto store
Which type of fluid will damage the brake system?

ATE SuperBlue is my favorite, I have used that one you mentioned from Valvoline for a few years, also not too bad, but if you aren't going to be changing it out to often, ATE is quite nice.

Check with your owner's manual to see if DOT 4 is okay. A lot of times, the chemistry difference between the DOT 3 and DOT 4 fluids are not compatible. They may differ and the rubber lines, seals, etc in your brake system may not do well with DOT 4. Sometimes manufacturer makes DOT 4 that are specified to be compatible cars where DOT 3 is required.

the only difference with DOT 4 is higher boiling points...
DOT 5 is the only of the above listed that is not compatible... it is a silicon based fluid, whereas the others are not... (they are glycol based, and composition depends upon manufacturer, not DOT rating)
they however, should not be mixed - there is a possibility of a chemical interaction, but highly unlikely...
