As long as the label on the bottle says its compatible with DOT 4, then you're okay.

I must relate an experience I had with Castrol DOT 4 brake fluid.

Castrol has been my preferred brand and as AFAIK, they have never sold DOT 3 so I have always used and recommended their fluid for all of my Volvo customers because I could tell them if they bought Castrol brake fluid, they were guaranteed not to get DOT 3.

About 10 years ago, some marketing genius decided to change the name from LMA to GT and touted the fact that the fluid was now synthetic and without consulting them, we changed to a different brand.

About 3 years later, I decided to call Castrol's tech line about Zinc/Phosphorous levels in their engine oils and asked about the change in their brake fluid whilst I had them on the phone.

Their rep let me know that it was a marketing gimmick and that the glycol they have been using has been synthetically produced long before they changed the label.

I quickly switched back to Castrol.

DON'T THEY HAVE ANYTHING BETTER TO DO AND I DON'T JUST MEAN CASTROL!! IF IT AIN'T BROKE WHY FIX IT!!
