fuel tank 45litre

I just joined my friends.I have 301 active 2018.I have not been able to accept my car, yet I have noticed that the fuel tank of my diesel vehicle is small.They did not want to accept it first. What can I do in this situation? Are there any other people with problems like me?

teacher, segment B is 45 liters. Design and environmental factors such as the low fuel consumption in the new generation vehicles - the increase in the number of gas stations - keeping the vehicle interior volume large have pushed the manufacturers to this situation. I used many model vehicles, megan-hyundai etc. The fuel tank of many models is 45 lt.

Thank you for your clarification. I thought it would be a problem when I wanted to sell it. It says 50 liters in the booklet. The service told me that it did not know about it.
