- Cars designed to run on regular gas have absolutely no benefit from running on premium instead. It’s just a waste of money!
- Even cars that call for premium gas don’t really need it. These types of cars usually have a high-compression engine, and the premium gas will give some extra performance, but only in rare circumstances (like when hauling a large load up a mountain).
