I’m going on a road trip and plan to get an XL fuel, with an extra can that I can add to it (yes, I know I’m asking for a heart attack). But I know that will throw off the flavoring, so I’m thinking I get Extra Sweet to balance out the extra fuel. But how sweet is extra sweet? Is it double the amount of syrup? 1.5X the amount? And if I’m adding sour, will that increase with the sweetness or do I need to get extra sour as well?

Quick question,

Are all the milks sweetened or unsweetened? Is there variety?
