Hello, I have 3 tanks of diesel when I pick up the car. I drove 85 km on the trip, and I estimate that there are still 50 km left when I return the car. How much diesel should I return? In addition, how do I refuel the car here? Do I need to go buy a certain amount of diesel first before refueling? I have a sedan with three trunks, similar to the Fiat EGEA ? Turkey Q&A
