I think you're right, they give us a large reserve for a margin of safety. I was returning home from a visit to family & my fuel gage started flashing ~ 100 km from home. It was @ night with gas stations closed. I just kept driving & made it home & the next day I filled up with 31 liters. I think Mitsubishi wants to look after us & make sure we aren't on the side of the road out of gas!!!
I didn't know what to do, so I didn't do anything
