Jason, thanks for the comments to the EPA.
it would also help if the fuel pumps in the US displayed liters rather than the pre-metric gallon. there are probably a number of ways that consumers could be better informed about their vehicles and their fuel economy if fuel pumps simply displayed liters and price per liter.
