so since the petrol is as expensive as super I refuel super. always when the tank watch is on the last stroke I refuel 14 – 15 l. the last 3 times I have used in average 9.5l to 100km with gasoline. so today I came to 8,2l with super. how much is still in the tank at the last red stroke??? 2 liters or?? because the first red 5 should be pure.
