I'm in Canada. Can I change my reporting units for US trips?

Reporting units at Fuelly are set per vehicle and can't be changed for individual fuel-ups. If you live in Canada where fuel pumps report in litres and then travel to the US where they report in gallons, you won't have any easy way to report those fuel-ups in Fuelly. Your best bet is to note the US fuel-up details and then convert the fuel volume to litres before entering at Fuelly. We have a form that can help you out.
