We store prices to three decimals, but we don't always display them at three decimals. If you go to
your fuel-up log, you should see prices to three decimals.
We'd like the ability to support multiple vehicles via SMS, but we haven't found a good way to to do it yet. The Miles Price Gallons [Note] format is very simple, and we're reluctant to tamper with that. If you have to precede [MPG] with an arbitrary number that represents the vehicle, we feel like that adds too much complexity and would lead to failed SMS messages. So it's something we're thinking about.
