What brake fluid can I use with Wilwood brakes?

I have a complete Wilwwod brake system on my Duster. It's a Wilwood tandem master cylinder with wildwood discs with Wilwood four piston calipers on all four corners. I had a lot of issues with faulty brake line flairing when doing the install, and wet through quite a bit of Wilwood 570 brake fluid getting all the issues taken care of. Now I'm replacing the 1" bore master cylinder with a 7/8" bore one to get more stopping power. The problem with the Wilwood fluid is they only sell it in small little bottles and it's kinda pricey. I want to switch to a commonly available fluid I can buy at any auto parts store. I did a web search and I found one soured that says the Wilwood 570 is the same as DOT 3 brake fluid. It even says it can be mixed with it. Has anyone run DOT 3 with Wilwood brakes and did it work out? If not DOT 3, then what fluid? Remember I want to stick with fluid that's commonly available, thanks.
