Here are the first few lines:

"## Vehicle"
"Name","Description","DistUnit","FuelUnit","ConsumptionUnit"
"Honda Civic","W-84729Z","0","0","0"
"## Log"
"Data","Odo (km)","Fuel (litres)","Full","Price (optional)","l/100km (optional)","latitude (optional)","longitude (optional)","City (optional)","Notes (optional)","Missed"
"2014-04-05","81575","39.9","1","51.43","0.0","47.8042","16.237","Wiener Neustadt","","0"
"2014-03-24","80919","30.23","1","38.48","6.14","47.8042","16.237","Wiener Neustadt","","0"

After the import, both the vehicle name and the vehicle description were both set to "Honda Civic".

I forgot to add: this was with Fuelio Pro 3.5.0.
