Dear Hossam,
There’s no problem and this is totally normal, especially if your car is automatic, even if it’s manual this fuel consumption is still within the reasonable range bearing in mind that the lanos is a bit above average in FC.
And as an advice there’s no need for you to use RON 92 at all in your car as the lanos works just fine with 90 and the only thing you will end up gaining is a loss of money Plus the increased fuel consumption.
Please do not hesitate to ask whatever you have in mind. :)
