This is my latest full tank mileage travel from Ipoh-KL-Ipoh.
70% highway and 30% city drive.
This time I able to achieve 505km with 36liter of petrol. (Best record was 525km)
It is about 14km/l with 100-120kph in average on highway.
My city drive in Ipoh was bad due to many stop and go during working hours (~10km/l)
