I use Tier 1 (top tier) fuels only. They contain far higher amounts of deposit control additives than other gasolines.
The additives are the only difference.

From AAA:
Gasoline Octane
Some motorists are under the false impression that premium-grade gasoline gives their car more power, better fuel economy, or a longer life. Some even think they are giving their car a "treat" by filling up with an occasional tank of premium. The reality is that using premium fuel in a vehicle that was designed to run on regular is a waste of money.
Premium fuel is needed by a handful of vehicles with high-performance engines. These vehicles require premium fuel to prevent pinging and its associated loss of power. Combustion chamber deposits in some older engines may cause pinging. In many cases, the least expensive fix is to use a higher grade of gasoline rather than to have the deposits mechanically removed.
Federal regulations require that all fuels sold in the United States contain detergents to prevent the build-up of deposits in the engine's combustion chamber. Several name-brand gasoline marketers promote their own fuel additive packages that have detergents formulated to clean up deposits. With few exceptions, their premium fuel contains the same additives as their other grades of fuel, including regular. Therefore, additives marketed to remove deposits, clean fuel injectors, and improve performance are generally viewed as a waste of money.
