Premix Controls

The UI is coming along nicely. Tapping "GAL (US)" will cycle between GAL (US), GAL (UK), and LITERS. Slider changes the fuel/oil ratio. The only real issue I have with this current UI is the mix slider metaphor vs the actual values. As you slide to the right, the number (50:1) increases, so the empty-to-full oil can icons make sense. But, technically the higher the mix number the less oil you will mix. So, 100:1 is less oil than say 32:1, but the icon shows a "fuller" oil can as you increment the number. So, do I keep it as is with the empty/full oil can meaning increase the mix number from 1:1 to 100:1 or do I change the icon to actually reflect the actual lean/rich mix ratios and amount of oil added? Seems counterintuitive.
