AC OFF 20% of the time. This is the second best I have managed so far. Close to 1/3rd or 60% IMO
As a rought estimate, yes
I am close to about 70% of the fuel guage and done 400km. As per my old routine reserve used to hit exactly at 416 to 427. This time I am expecting around 450. Lets see. Will post when it happens. However, after several refills I have concluded that reserve lights on when around approx 6 litres is left in the tank.
HOBC's addition made a lot of difference.
Only Petrol at half mark - 250km
Petrol HOBC mix - 295km
I will be sharing the cost per litre details with everyone here soon which will show which is the cheapest ratio of mix to go for with the best mileage in the range.
