Coolant capacity: confused?

Im doing a flush on my 08 350. Most of the sites state that the capacity is 27.5 quarts. I went to the dealer and they state 30.6 quarts. Also I see alot of people just adding 4 gallons of concentrate, what mix will I end up if I add 4 gallons?

Main system is 30.6 qts, fuel cooler is 2 qts. 4 gallons of concentrate directly in the main system will put you at a 52/48 mix. Close enough. Or do the fuel cooler and measure out to get a 50/50 mix between fuel cooler and main system. 32.6 qts total between the two. 16 qts in 4 gallons.
