We can get that required antifreeze additive for -20
o
C is 13.5L
Difference value between -30
o
C and -20
o
C is 4L
For the difference value 4L, another 50% of that is required and necessary, because of before
adding antifreeze additive, a part of coolant must be drained out, and antifreeze additive in this part
of coolant will be drained out too.
So required antifreeze additive is: 4L+50%*4L=6L.
