Update : Coldest morning so far (-30°C). Plugged the EBH for ~3 hours. c°WT showed ?? (didn't check it before starting). I had to use my lights and defroster so FE way down... Did 6.5 LHK AVG.
On the returning trip, cold weather (c°WT showed -22°C when starting), was keeping my usual ~70 Km/h speed at 16 TPS, but instead of doing 4 LHK, I was doing 5 LHK... Anyway, did 5.9 LHK AVG...
Tank data : hit 600 km and little bit before the 1/4!
Worst day ever!!! Never drive in such conditions if you can avoid to
