I was wondering exactly how much fuel goes in a tank before running dry. I was on the road this weekend in Croatia and when just leaving Dubrovnik the warning light came on. I had then 356 km (about 224 miles). I made it to the fuel station with 401 km (249 miles) and I managed to put 21,5 lt (5,68 US gal). Computer said 5,3 lt/100 km (44 mpg), which according to my calculation is accurate enough.
How much more fuel did I have left, considering that I always fill up to the neck? Manual states 22 lt (5,8 US gal), but once I refueled 22,3 lt (5,89 US gal).
Thanks in advance,
Martín
