Yeah, I think the letter was dated in Aug/2013. The case I got was stamped 7/2013, so it is almost a year old. The tins are sealed, they should still be fine, right?

As far as it being important that it's blue, its not important in a technical sense. Just convenient when bleeding, even thought I don't go by the color change so much, but just by volume, its just "fun" to look at. Its one of those things that are completely unnecessary, but neat to have I suppose.

The 4.4 and the E60 need their's changed, and during a brake service, I go through 1 1/2 to 2 tins of fluid. So by the end, I'll have about 2 tins left of the stuff.

The thing I found interesting about superblue was after its service date in the 4.4... I did notice it wasn't a royal blue anymore, but a very slight creamy blue. I am assuming it is the moisture that it picked up?

Yeah, I didn't know it was always illegal. I was reading the articles around on the net and seems like it was something that went back and forth for the past 15 years or so. Just confusing how much fuss was made about it's color, when antifreeze has different colors. Just found it interesting. But at the rate I am going at with the SES light on the 4.4 and the quarks the E60 has, I'm ready to dump some Advance Auto Dot 3 BOGO $2.99 special and hope for the best. Or be prepared for multiple thousand repair bill to replace the entire system, hahaha.
