Well you could be right, maybe the extra length is not that much. Pressure drop is linear dependent with the Length, but there are many other factors involved so maybe I am over concerning about the length . Core size you mean the radiator right? Well I have 13 rows, not too bad

Uf, my tack usage is similar to yours or less. My temps get easily raised to 130-135°C (even If I am rushing a bit out of the track). In my opinion, after reading a lot, this is too high temperature. Look at the pressure drop in the link above due to the thinner oil...
