Thank you for the quick response, Qsilver7. Any ideal what ! means by green bottle of HT12 at left/lower in the picture? Also, looking the 2 tables, for our F15s, 1 table shows both can be used after 01.07.2018, but the other shows only blue G48 can be used in before 03.06.2018.
By compatible, definitely it means you can use either of them, but would mixing/topping them in cooling system OK like my dealer did?
Just want to get to the bottom of this, to make sure we do the right things for our Bimmers!
