I have a Lanos 99, when i use 90 fuel i do 200 KM for each 20 Liter in city and 300 KM on high way, when i use 92 fuel i do 150 KM for each 20 liter in city and 250 KM on high way.
Is this a normal consumption or do you think i have a problem with my car, taking in to consideration that i am always driving fast.
Thank you for your help.
