Hi. It is also called DOT 5
I use it in several of my older trucks and cars that I don't use very often. I found it easy to work with as long as you take you time bleading, NO pumping up. I even have it in a 62 C50 with a hydrovac. Gravity blead when you can work best with DOT 5. The key is dont mix with DOT 3. Start out with completely new system.
