All of the documentation I've seen states just over 6 US gallons combined capacity. I guess the fill lines could take some more but . . .
On 10/16/2015, I could get no additional fluid in the tanks. I even tried again a few hours later to be sure. It was behaving the same as it did when I refilled the system on 1/24/2015. Based on my experience, I'm more apt to believe that 6 total gallons is closer to the actual capacity than the 7.5 that you have stated.
That, or I'm missing capacity and I should have been able to drive a great deal more than the 10000 miles I did between the low level warnings.
