The independent laboratory testing compared gasolines that meet TOP TIER™ standards often marketed to consumers as having enhanced, engine-cleaning detergent additives with gasoline brands that do not participate in the automaker-backed program.

Such carbon deposits are known to reduce fuel economy, increase emissions and negatively impact vehicle performance, particularly on newer vehicles.
