Gasoline, is gasoline, is gasoline BUT the additive packages and in particular the detergent additives are what can make a difference. Using low detergent fuel over the long run can and does allow a mixture of Olfins (wax) and dirt from the "Puff Back" from the last cylinder to fire when an engine stops and rocks back slightly to accumulate in the intake manifold. Not a big deal unless you are using port fuel injection (like HD). Over time the accumulation of these deposits on an injector will cause the engine to run leaner and thus start harder (particularly in cold ambient temperatures), idle rougher, hesitate off idle, and loose top end performance. Using a major name brand fuel usually guarantees sufficient detergents to keep this accumulation from forming. In the 80's the Auto Manufacturers released Technical Service Bulletins that specified only certain brands of fuel if you wanted to keep your warranty in effect for your fuel injectors. I worked for one OEM at the time and within a week or so of the TSB release almost every name plate gasoline company added a sufficient detergent load to Regular fuel to keep the problem from developing, and premium fuel usually has enough of a detergent load to s-l-o-w-l-y clean somewhat plugged injectors.
