STP? heavy-duty brake fluid DOT 3 is specially formulated to coax optimum performance out of disc or drum brake systems in today's cars and trucks.

Prestone? DOT 3 synthetic hi-temp brake fluid is designed to provide an extra margin of boiling point protection. The mix of polyglycol ethers ensures hot brake-system operation will not create dangerous vapor. This delivers braking power when needed by avoiding a spongy pedal. Both wet and dry boiling points exceed the minimum government standards. A comprehensive inhibitor package protects vital brake system metals.
