Hi, I assume this is a silly question but my 2008 Focus just came from service (a local garage) and they said it also needed the brake fluid replaced. When i came home i checked the invoice and it said they used DOT 5.1. But the owner's manual https://www.carmanualsonline.info/fo...-manual/25#244 says the recommended brake fluid is DOT 3. Is this a problem?

 

wtf is dot 3
