Gas Savings & Budgeting
Most people can tell you their rent to the dollar and their fuel spending to the nearest shrug. That gap is the reason gas feels expensive in a way other bills don't: it arrives in $40 and $60 pieces, several times a month, and never lands as a single number you can look at.
This is the category that produces that number. The guides here work in cost per mile rather than cost per fill-up, because per-mile is the only unit that lets you compare a commute against a road trip, or one car against another, without doing mental arithmetic at the pump. Once you have it, the rest of the site gets more useful: every vehicle guide, route cost, and savings tactic is denominated in the same terms.
Start by measuring, not optimising. A month of honest tracking almost always turns up something a tactic wouldn't have caught: a second vehicle doing more miles than anyone realised, or a habit of topping up at the most expensive station on the route. Fixing that is worth more than any single fuel-saving trick, and it's the reason the guides below lead with budgeting before they get to tactics.
