Great site guys! Just one point, I think the fuel cost/litre should have 3 decimal places. Here in Montreal, and the rest of Canada, fuel is sold in cents/litre, i.e. ¢79.9/litre,¢104.6/litre etc.
We round the price to two decimal places on the car profile page to conserve space, but on your fuel-up log (example), the price is to three decimal places.
Do you want to see three decimal places on your last ten fuel-ups as well?
