[QUOTE="ionbeam, post: 1120423, member: 277"] The demands on fuel over the last ~20 years have changed as engines have gone from lazy carburetor, imprecisely controlled open loop systems to fuel injected, highly tuned closed loop power plants with sensors never before imagined on street engines. Along the way combustion deposits on valves and fuel injectors became significant problems in addition to the usual combustion chamber and ring deposits. This resulted in Top Tier Gasoline being formulated with detergents in all grades of gas. As time progressed some of the bigger gas companies started adding even more detergents in the higher grades.
