One of our MidState Club members ordered some Castrol fluid for his clutch and brake system, and noticed a new bottle advertising a new formula. After contacting Castrol the response below is what he received. It's interesting info for anyone who gets the new bottle. The bottom line is, you can still add / mix / use the GTLMA fluid on our brake system parts. Enjoy!

The product formula has not been changed; Castrol GTLMA has always been a fully synthetic brake fluid. The improved wet boiling is 329°F(169°C) GT LMA is approved for older cars that recommend compatibility with Girling Brake Systems and natural rubber seals. GT LMA combines both DOT 3 and DOT 4 performance and exceeds both specifications. Both DOT 3 and DOT 4 specifications call for glycol based brake fluid and address the fluid boiling point, pH, corrosion protection, stability, seal compatibility and anti-wear properties. The primary difference is with low temperature viscosity and the wet-dry boiling point. Compared to DOT 3, DOT 4 has a more stringent requirement for dry boiling point (446 degrees F versus 401 degrees F). DOT 3 performances requires greater fluidity or lower viscosity at low temperature. It is very important that you follow your owners manual and use only the product recommended for each specific application.
