TOP TIER™ Fuel Standards To Target Injector Deposits

SAE International recently published an in-depth article examining how evolving fuel standards and engine technologies intersect to shape vehicle performance and efficiency. The piece explores how the growing prevalence of gasoline direct injection (GDI) engines has transformed the automotive landscape — and why inconsistent fuel additization across North America may be holding these advanced engines back from achieving their full potential.

As the article explains, a forthcoming update to the TOP TIER™ fuel program aims to address these challenges by enhancing fuel cleanliness and performance standards. In doing so, it underscores the critical connection between modern engine design, fuel quality, and long-term efficiency — offering valuable insight for both industry professionals and everyday drivers alike.
